Compressive Sensing Based Active Imaging System Using Programable Coded Mask and a Photodiode

There has been significant progress in the field of compressive sensing (CS) and its applications various fields recent years. Here, we have developed a CS-based active imaging system that does not require pixelated array detector but instead uses transmissive spatial light modulator as programmable coded mask. Single-pixel cameras (SPCs) many such terahertz (THz) infrared (IR) imaging. With an increase number pixels, detectors can become expensive, especially THz IR regimes. In this article, explored concept illumination, which could be helpful developing SPCs. The article focuses on development SPC, analysis how masks affect quality reconstructed image.
