Abstract (en)
[origin: CA3125842A1] The invention relates to an optical device for arrangement on a detector provided with an infrared sensor in order to modify the visual field of the detector, comprising two conical mirrors, the primary mirror collecting the infrared radiation coming from the sub-ceiling layer around the device for returning it onto the secondary mirror which, itself, reflects it to the sensor of the infrared detector.
