Other AbstractBased on compressive sensing,a new photon-counting imaging system was proposed.Using single-photon counter as the detector,this point-type detector was used to detect ultralow light and obtain the two-dimensional image while the plane-type detector was not very developed.By performing simulation on the computer,the feasibility of the system was verified.The effects of the single-photon counter′s dark count rate,quantum efficiency and measurement noise on the quality of the obtained image were discussed.And compressive sensing theory was introduced.In order to obtain a better image and faster computing speed,a new image reconstruction algorithm,SpaRSA-DWT,was proposed.The experiment results show that SpaRSA-DWT needs less measurement and iteration times compared with the typical IWT algorithm,and is more robust to noise.
