Setup for photo-reflective sensors

[Okutomi]

I prepared photo-reflective sensors (PS) and their drivier circuit which are originally designed for DPF experiment.
We use the PS for local sensors facing on the recoil mass during the assembly work.
Details:
JGW-1605845: Photo sensor assembly for VIS installation

I checked connections around PS and that output signals are obtained on the digital system.
Next time I will calibrate them and measure their noise level.

Probably you would know, you can directly see the infrared light from the LED by your cell-phone's camera, maybe (depend on an optical filter in front of the camera's sensitive part).
