OPTICAL MODULE, OPTICAL OBSERVATION DEVICE, AND LIGHT EXPOSURE DEVICE

摘要

An optical module (1A) includes a polarization beam splitter (10) that receives input light (L1) including a p-polarization component using a light splitting surface (11), a first polarization element (20) that rotates a polarization plane of the input light (L1) transmitted through the light splitting surface (11), a first reflective SLM (30) that modulates the input light (L1) to generate first modulation light (L2), a second polarization element (40) that rotates a polarization plane of the first modulation light (L2) passing through the first polarization element (20) again and reflected by the light splitting surface (11), and a second reflective SLM (50) that modulates the first modulation light (L2) to generate second modulation light (L3). The second modulation light (L3) passes through the second polarization element (40) again, is transmitted through the light splitting surface (11), and then is output.
