How image rotation in an aerial thermal-vision channel affects the interpretability of images

摘要

This paper discusses the effect of rotating the image of scenes observed in an aerial thermal-vision channel, constructed using a subarray photodetector unit operating in the time-delay and accumulation regime and microscanning over a frame. It is shown that, when an image is formed in the television standard, its interpretability is not appreciably degraded if the angular velocity does not exceed 30?deg/sec. When persistence of vision is taken into account, the interpretability is not degraded if the angular velocity does not exceed 6?deg/sec.
