Encoding the target optical field based on DMD, UPOLabs Single Pixel Imaging Experimental System collects encoded optical field information through a single-pixel detector. It is an excellent option to reconstruct your target scene images through different algorithms including classical correlation calculation algorithm, differential correlation algorithm, and compressed sensing algorithm. This UPOLabs Experimental System contributes to single-pixel imaging experimental teaching in universities and is suitable for scientific research work related to reconstruction algorithms.
