Abstract
Some embodiments are directed to a wide-field imaging system for the infrared spectral range. The system can include a vacuum chamber that is optically open for the passage of the field rays originating from the scene to be imaged, a cooled dark chamber placed inside the vacuum chamber and provided with a cold diaphragm, an infrared detector placed inside the cooled dark chamber, and a device for optically conjugating the field rays with the detector.
