Abstract-A Terahertz Spatial Light Modulator for Imaging Application
Saroj Rout, Sameer Sonkusale,
This chapter covers another case study of an all solid-state metamaterial based terahertz (THz) spatial light modulator (SLM) using the HEMT embedded metamaterial based modulator described previously. The motivation behind such a design is first introduced followed by an introduction to single-pixel imaging. Then, the design and assembly details of the spatial light modulator are discussed. The SLM is demonstrated by raster scanning a 6 × 6 image of an occluded metal object behind a thick polystyrene screen using a single-pixel THz imaging setup.
