PURPOSE:To provide a pixel deviation detecting device of the optical camera which can precisely detect a pixel deviation even during observation with a small number of components. CONSTITUTION:The laser light, which is emitted by a laser light emission device 5 incorporated in the tip part of an optical camera main body 2, and is irradiated on an optical system condenser lens 3A from outside the range of the angle of visual field is photodetected by laser light photodetection sensors 6A and 6B through optical system condenser lenses 3A and 3B and an optical system spectral lens 4 and converted into an electric signal consisting of the photodetection position and photodetection quantity of the laser light, so that the signal is outputted as measurement data to a photodetection data processing part 8. The photodetection data processing part 8 performs processing of the measurement data from the laser light photodetection sensors 6A and 6B to calculate the quantities of pixel deviation of observation image pickup elements 7A and 7B with deviation generated, which are caused physically linked with the laser light photodetection sensors 6A and 6B. |
