Method for giving a depth impression in a thermal image and camera for carrying out the method

摘要

The method employs a camera with an optical system (1) forming an image on a scanner (2), which produces a periodic vertical displacement. A dichroic mirror (G) divides the luminous flux between two infrared detectors (D1,D2), working in frequency bands where the atmospheric transmission is good and poor respectively. The signals from the first detector are amplified (A1) and applied to the red and green input terminals of a colour video monitor (3). The outputs from the second detector are amplified (A2) and applied to the input to the blue terminal.
