The phase height model is developed in the phase measuring profilometry, while the geometry transformation model is proposed in the structured light method and the active stereovision. However the inner connection or coherence of them has not been clearly discussed. In this paper, the gap between them is bridged. The phase height model is reasoned from the geometry transformation model, which can...
Laser sources with limited wavelengths are commonly used to calibrate the phase delays of liquid crystal variable retarders (LCVRs). However, the parameters describing the phase delays obtained in this manner in certain bands do not match the parameters in the wide-bandwidth working channel employed in polarized imaging detection systems based on LCVRs, which results in deviations in the detection...
