Turning angle sensor based on a periodic optical raster and photodetector matrix in full-frame mode
- 36 Downloads
A new principle for the construction of an angle sensor based on a periodic optical raster and a photodetector matrix is proposed. An algorithm for determining the angular position of the axis is considered. Theoretical and experimental estimates of the error in measurements of the angle and a comparison of the estimates are presented.
