Compact infrared cryogenic wafer-level camera with a wide field of view equal to 120°. Its total track length is equal to only 4 mm. It is made of two stacked microlens arrays, which are directly integrated on the infrared detector. By merging the optics with the detector, the concept is totally compatible with cryogenic constraints. For details see de la Barrière et al., pp. 1049-1060.
