VARIOSCAN high resolution is a thermographic system for the
wavelength ranges of 2 – 5 µm (Model 3022) and 8 – 12 µm (Model
3021). Thus the system covers both atmospheric windows.
The camera operates on the principle of object scanning. The object is
scanned through a two-dimensional reflecting scanner.
The horizontal scanner scans in lines, with 360 pixels each being
recorded at a frequency of 135 Hz. This scanner operates as a
resonance oscillator driven by a DC motor.
