PURPOSE:To eliminate the tilt compensating prisim and thus eliminate the deflecting drift of the image pickup tube, by giving the process to the digital code received the A/D conversion and thus displaying the panoram-type infrared-ray image in an upright image. CONSTITUTION:The infrared rays are scanned by scanner 26 and then converted into the electric signals by detector 28 and through the lens system and mirror 27 each. These electric signals are then sent to A/D converter 30 via multichannel amplifier 29 to be stored in memory 31. On the other hand, the angle of rotation of the rotary optical system is detected by rotary position detector 32, and the detected output is sent to read signal generator 33. In generator 33 the reading address is changed for the contents memorized in memory 31 to give the display of an upright image. |
