There is a long history of using angle sensors to measure wavefront. The best example is the Shack-Hartmann sensor. Compared to other methods of wavefront sensing, angle-based approach is more broadly ...
This post is a quick look at the quite popular Rotary Angle Sensor module CJMCU-103. The CJMCU-103 rotary angle sensor/rotation sensor module is good for detecting an absolute rotation position. The ...
