The coded photography acquires coded coupled scene information by modulating the illumination, optical path and sensors, with decoding calculation and image signal processing to achieve high-precision scene reconstruction, thereby breaking the limitations of traditional optical imaging models and physical devices, effectively improving the information transmission efficiency of the imaging system. With the continuous innovation of imaging components such as light sources, optical elements, sensors, and the emergence of new imaging methods, the coded photography technology has achieved rapid development and has a broad application prospect. In this paper, progress of the coded photography technology is reviewed, and three aspects such as illumination coding, optical path coding and sensor coding are emphatically introduced.
