Page 29: Technical Explanation
Technical explanation Distortion correction pattern Since the silicon substrate of LCOS-SLM is extremely thin compared to the glass substrate, it is difficult to maintain it in a perfect plane, and initial shape distortion of several [µm] remains. Therefore, when a plane wave is made incident to emit the plane wave, the remaining distortion of the silicon substrate, which is the mirror surface, causes wavefront distortion as shown in Fig. -
