Abstract

The designed wedge scanner has conventional raster scan pattern canceling the movement along one axis by rotating opposite direction, in which case the alignment of these two wedge scanners affects the imaging performance of the system. To align the wedge scanners more efficiently and effectively, 2nd split rays are used. The ray tracing was performed to predict the precision achievable. The sensitivity according to the movement of the scanner is dependent on the refractive index and slant angle of the wedge and was about 350 times more sensitive when the angle between two vertexes of wedge scanners reaches 1°. The goal was successfully achieved below 0.6 mm in the screen 5 m away, which is 1/4 of the alignment goal.
