Spatial light modulation device, optical processing device, coupling prism, and method of using the coupling prism

摘要

On the virtual reference line (9), the mirrors (3, 7) are arranged, and the reflective SLM (5) is arranged at a position shifted in the vertical direction from the virtual reference line (9). Input light input along the virtual reference line (9) is reflected by the mirror (3) and enters the reflective SLM (5). The light modulated by the reflection type SLM (5) and reflected by the element reflection surface (5c) is reflected by the mirror (7) and output as a virtual reference line (9).
