Abstract (en)

[origin: WO2022038044A1] The present description relates to a system (10) for acquiring images of an object (12) comprising a stack of layers the total thickness of which is smaller than 600 µm, said stack comprising an image sensor (14) comprising a matrix array of photodetectors (16), a source (20) of an emission (RF) having a thickness smaller than 400 µm and comprising first and second opposite faces (22, 24), the second face being oriented toward the image sensor, the area density of the energy flux emitted by the source via the first face being higher than 100 μW/cm2, the ratio between the area density of the energy flux emitted by the source via the second face and the first face being lower than 0.4, the transmittance of the source to said portion of the emission being higher than 15%, and an angular filter (18) that covers the image sensor and that is interposed between the source and the image sensor.
