Review of crosstalk between pixels in division of focal plane polarization camera
Division of focal plane polarization camera is a widely used integrated polarization imaging system. Crosstalk between pixels of the micro-polarizer arrays (MPAs) is the unique interference factor in such system, and its crosstalk light intensity varies with the polarization characteristics of the incident light, bringing errors to the measurement of the target’s polarization information. This paper reviews the development of polarization crosstalk models and summarizes all the factors affecting crosstalk identified in relevant researchs. Taking sensor parameters and optical system parameters as key factors, this paper discusses the cause-effect model of crosstalk in cameras and its relation to temporal noise. It analyzes the results of parameter changes caused by crosstalk, primarily summarizing the crosstalk’s factor correlation, experimental repeatability, error randomness and parameter calibration. Finally, this paper prospects the future development trends of crosstalk models.
