Revision as of 21:55, 9 December 2011

Current camera in the flag is placed in the cylindrical tube of the flag. Camera can be slided into the flag, and the distance can be controlled. Camera itself is cylindrical shaped, and placed into a cylindrical tube. The tube has 2 cm of inner diameter and 3 cm of outer diameter. Camera has 2 cm diameter.

Hardware Triggering The Camera

Pulse signal need to be send to "TTL IN 1" (pin# 6, Blue), "TTL IN 2" (pin# 7, Violet) or "TTL IN 3" (pin# 10, Pink).

At JAI Camera Control Tool, set

c) Acquisition and Trigger COntrol:
"exposure mode" -> "Pulse-width control"

e) Digital I/O:
"Line Selector" -> "Line Source" -> "Hirose TTL In 1" (or In 2 and In3, depending on wich TTL In signal is being sended.)

Third Party Software for JAI GigE Vision Cameras:

[1]

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

[2]

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?

6 Way Cross

Diameter of the window: 3 inches.

Distance from the 6-way-cross to the floor (Not from the center, but from the bottom window to the floor.): [math]37\frac{1}{4}[/math] inches = 94.615 cm.

The distance from the Center of HRRL beam pipe to the floor is: 106.3 cm

From the center of the 6-way cross to quartz window: 11.685 cm

The distance from the center of the OTR target (also the center of the 6-way cross) to the closest position we place our first lenses is 13 cm.

Edge to edge OTR cone diameter size ([math]4\theta[/math] angle, ) at this distance is 2.665 cm.

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:

[math] M = \frac{f_2}{f_1} [/math]

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;

Dear Sadiq,
The LCP01T can hold 2" lens.  The maximum thickness for the optics would be 17.8mm (the part in contact with the retaining ring).  
You can find the drawing for the part at http://www.thorlabs.com/Thorcat/21400/21473-E0W.pdf
Please let me know if you have any further questions.

Imaging System Test

Cage system were constructed, and 3 lenses with focal length of 500 mm, 100 mm, and 65 mm used to take image.

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:
Dear Sadiq,
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

Slit-Aperture vs. Potentiometer-Resistance

Slits has two side: Copper and White metal. There are resistors connected the bolts on the copper side. White metal side has smaller aperture. Thus white metal side should face up stream of the beam line, since this side define beam aperture.

Copper side - Downstream side

This copper side, this measurement is useless.

Linear Fit for Data

Data for 37.6 mm aperture was excluded from fit because it is far off from the straight line (manufacture claims biggest aperture is 35 mm, could be we are exceeded this value).

Pot resistance vs Aperture size

The fit is:

When units are mm for Slitize (S), k[math]\Omega [/math] Resistance (R)

Control Circuit

Design:

Relay

Switch

Old Power Supply: Max Current = 0.83 A: This PS does not have sufficient current supply. When we drive motor, we need current of 1 Amp. When the motor just started, current can go up as 1.7~1.8 Amp. So, we need PS with 12 VDC and Max current at lest 1.8 Amp.

Beam Pipe for Quad7

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.
