ABSTRACT:
The thermal imaging device comprises an IR-transmitting scanning polygon arranged behind an objective system. The polygon rotates about two mutually perpendicular axes, i.e. about the optical axis of the device and about the axis of rotation of the scanning polygon which is perpendicular thereto. The rays which emerge from the polygon pass through a reversing optic, which also rotates about the optical axis but with half the angular frequency of the scanning polygon around this axis. Behind this a multichannel IR detector array is arranged, to which a multichannel summing amplifier is connected. The amplifier is synchronized with the frequency of the rotation of the scanning polygon about its own axis. This rotation of the scanning polygon at the same time constitutes the radial deflection frequency for displaying the image.
