Third Party Software for JAI GigE Vision Cameras:

National Instruments - JAI GigE Vision cameras are compatible with NI's Vision Acquisition Software and related image processing modules, including integration with the LabVIEW graphical programming environment.

NI Machine Vision Software

National Instruments has been a leader in machine vision and image processing for nearly a decade and currently supports thousands of different cameras. To acquire, display, save, and monitor images from cameras, use NI Vision Acquisition software, which is included with all NI frame grabbers and sold separately for FireWire and Gigabit Ethernet image acquisition. To process images, NI Vision software comes in two different packages: the Vision Development Module and NI Vision Builder for Automated Inspection (AI). The Vision Development Module is a collection of hundreds of vision functions for programmers using NI LabVIEW, NI LabWindows/CVI, C/C++ or Visual Basic. Vision Builder AI is an interactive software environment for configuring, benchmarking and deploying machine vision applications without programming. Both software packages work with all NI Vision frame grabbers and the NI Compact Vision System.

## Labview error message

It looks like the NI software from 2009 was downloaded. There are 2 more recent versions. Perhaps if we use the latest software the error message will go away?

## OTR with Al

Ring actuated Irises are designed for integration into a 60 mm cage assembly, where the movement of a lever actuated iris would be hampered by the cage rods.

Price: $75.50 ## Lens Diameter: 5 cm. We can use 3 lens system to hold image directly at the sensing area of the CCD camera. Sensing are of the JAI CCD camera is 6.49(h) x 4.83 (v) mm and field of view of our interest has a diameter of 1 inch. Since OTR is placed 45 degree to vertical plane, one of the dimension of the OTR image actually is 1.796 cm. If we put this to vertical dimension of the camera and put the other dimension of image on the horizontal dimension of the camera, the magnifications we need to hold the view of our interest on the 50% of the sensing area of the camera will be: HRRL Emittance Optics Lay Out: In this telescope system magnification will be: So, we need to pick 2 lenses with optical length satisfy above ration. From the lower port of the 6-way cross the the floor is 94.6 cm. So, we have 90 cm place to place our camera system. So, I suggest we order camera with focal lens of 50 cm, 20, and 6, cm. These pieces can produce magnification that is small enough for experiment. To avoid delay of experiment due to possible miscalculation, it is prudent to order 2 more lenses. One of them should be focusing and other one should be defocusing. In that case we can extend our optics as shown in following 2 figures; Lenses for Basic Optical System Design:  Code Quantity Diameter (inches) Focal Length (cm) Coating Price for Each ($) link LB1723-A - N-BK7 Bi-Convex Lens 1 2 6 ARC: 350-700 nm 30 [5] LB1630-A - N-BK7 Bi-Convex Lens 1 2 10 ARC: 350-700 nm 29 [6] LB1909-A - N-BK7 Bi-Convex Lens 1 2 50 ARC: 350-700 nm 29 [7]

Out most ring on the target has a diameter of 27 mm.

#### Lights and Laser on

Following images are taken within distance of 45 cm (from target to CCD sensor).

Dr. Kim's suggestion:
Good Job!
If you have some free time, please would you try to improve brightness of the captured image?
As you can see, the captured rings are somewhat dark now.
If it is needed, you may install a small LED illuminator toward the screen and a light-shielding box around the cage.
The bigger lens are also helpful to improve brightness.
Sincerely yours,
Yujong Kim

## Final Test

1. When fully closed, shows 0.17-0.18 cm (1.7-1.8 mm). Slit does not close fully, there is very little gap that I couldn't measure. I estimate that is around 1 mm. So, I estimate my error on the energy slit to be 2 mm at maximum.

When switch to close, "Full clos" light is on.

2. Turn the switch to open. Then the reading is getting bigger.

3. When fully opened, the "Full open" light is on. Then we need to put turn the toggle switch to center. The reading shows 3.47 - 3.52 cm (34.7 - 35.2 mm). I measured the distance between two slits. It was 3.5 cm.

I would record my readings with 2 mm error. So, biggest gap between slits would be 3.5 +- 0.2 cm.

Need to order 2 flanges from Duniway (www.duniway.com):

1. F450-200 R

2. F458-000 N

# 3rd JLab Flag

The third Jlab flag does not have switch. We can not control remotely with electronically.

Applying pressure to upper gas inlet of the flag will push target holder into the 3-way cross. Without pressure, holder goes back.

We can control by gas pressure. If we have long enough pipe for gas, we can control it remotely.

JLab flag is missing one 458 (10 hole) flange. We need buy it, if we are using it.

From control room to the end of the 0 degree beamline, we need about 20 meters of wire.

### 2 Flags

Each Flag needs 6 wires

2 Flags at accelerator side: There is one wire with 12 small wires inside already.

### Energy Slit

Energy slit needs 11 wires: Need to get it from IAC 20 meter long wire.

### 3rd Flag

Flag at experimental side: Need wire

## Experimental Side

From Control room to the where the Annihilation target and ion pump is about 25 meter.

### HV Cable

HV Cable for Ion pump.

### Annihilation Target Flag

One Flags needs 6 wires.

# GigE Vision Camera

Prosilica GC1290 GigE Vision Camera

S/N: 02-218A-20132

MAC:000F312098

## Start Camera

Start->All Programs-> Allied Vision Technologies

For first time start "GigEIPConfig" to acquire IP addrees.

To use camera start ""GigEViewver".

## Triggering

The User Trigger pulse width should be at least three times the width of the Trigger Latency

Trigger latency: 2µs for non-isolated I/O, 10µs for isolated I/O

Trigger jitter: ±20ns for non-isolated I/O, ±0.5µs for isolated I/O

## Camera Pin Connections

### Camera In 1 and Camera In 2

Input signals allow the camera to be synchronized to an external event. The camera can be programmed to trigger on the rising edge, falling edge, both edges, or level of this signal. The camera can also be programmed to capture an image at some programmable delay time after the trigger event.

Camera In 1 is isolated and should be used in noisy environments to prevent false triggering due to ground loop noise. Camera In 2 is non-isolated and can be used when a faster trigger is required and when environmental noise is not a problem.

### Camera Out 1 and Camera Out 2

These signals only function as outputs and can be configured as follows:

Exposing ----- Corresponds to when camera is integrating light.

Trigger ----- Ready Indicates when the camera will accept a trigger signal.

Trigger ----- Input A relay of the trigger input signal used to “daisy chain” the trigger signal for multiple cameras.

Readout ----- Valid when camera is reading out data. Imaging ----- Valid when camera is exposing or reading out. Strobe ----- Programmable pulse based on one of the above events. GPO ----- User programmable binary output.

Any of the above signals can be set for active high or active low.

Camera Out 1 is isolated and should be used in noisy environments. Camera Out 2 is non- isolated and can be used when environmental noise is not a problem and when faster response is required. Camera Out 1 will require a pull up resistor of greater than 1Kohm to the user’s 5V logic supply. See Trigger Schematics in Addendum for wiring information.

### RS-232 RXD and RS-232 TXD

These signals are RS-232 compatible. These signals allow communication from the host system via the Ethernet port to a peripheral device connected to the camera. Note that these signals are not isolated and therefore careful attention should be used when designing cabling in noisy environments. Isolated Ground Isolated Ground must be connected to the user’s external circuit ground if Sync Input 1 or Sync Output 1 is to be used.

### Signal Ground

Signal Ground must be connected to the user’s external circuit ground if Camera Input 2 or Camera Output 2 is to be used or if the RS-232 port is to be used. Note that Signal Ground is common with Power Ground however it is good practice to provide a separate ground connection for power and signaling when designing the cabling.

### Video Iris

This signal can be used to drive the video input of a video iris lens. See Addendum.

### Reserved

These signals are reserved for future use and should be left disconnected.
