Class Information
Number: 356/152.3
Name: Optics: measuring and testing > Angle measuring or angular axial alignment > With photodetection remote from measured angle > With reflection of a unidirectional source beam from a retroreflector
Description: Subject matter including a reflective surface at a remote object from which a source beam directed along one axis reflects back to a source and photodetecting station colinearly or in parallel with respect to the source direction.
