1) improve set screw connection to shaft of motor. Set screw kit ordered. DONE, CWS Feb 5, 2023.
2) drill out motor mount plate to allow mounting to a tripod, with 1/4-20 hardware. DONE, EKU, Feb 6, 2023
3) test it out in lab. For Canon 6D we can take video, and use MATLAB optical flow tools to process it. Be sure to use highest resolution video capture and ALL-I compression option. See https://thepointsguy.com/news/united-pqp-deposit/ /
Lab tests:
Set up tests with an LED and a bifurcated fiber with two outputs. Tried to take videos with the spinning plexiglass at various points along the path. Notes/results/observations:
- The plexiglass changes the location of the focus enough that you have to try to refocus, but it is very hard to tell when you are in focus. Here is a video of going through focus (note that it is a normal donut without the plexiglass: IMG_1618.MOV
- There is clearly less differential motion when the plexiglass is close to the camera (IMG_1619.MOV) compared to when it is far away (IMG_1620.MOV). Currently, the images are saturated, though.
