Detection Model and Correction Method for Quadrant Detector-Based Computational Ghost Imaging System

Quadrant detector (QD) is a widely adopted position sensor. By adopting ghost imaging, the four-channel outputs of the detector can be multiplexed to position and image the target simultaneously. However, the lens defocus and detector blind area distort the detected laser intensities, which would in...
