Electro-optical imaging system.

摘要

An electro-optical imaging system includes a scanning head, comprising a rotating polygon mirror to sequentially image different points in the field of view on to a detector compensation for vibration in the azimuth direction, i.e. the direction in which the scanning head rotates, is provided by utilising a signal derived from a vibration sensor to alter the gating period during which the video output system from the detector is output. Compensation is also provided for vibration occurring in the vertical direction.
