Abstract: The invention provides a lens-free infrared imaging device (1) intended to image a sample (2), comprising at least one light source (3, 3a, 3b) configured to emit a light according to several wavelengths of the infrared range, and at least one sensor (4) configured to detect some of the light emitted having interacted with the sample, said sensor comprising a plurality of pixels (41), the device being characterised in that the sensor (4) is configured to detect a reflective part of the light emitted. The invention also provides a method for manufacturing this device.

Abstract: The invention relates to a radiation source which comprises: a support (400) provided with a wall (410); a membrane (200) comprising two faces, the membrane (200) being adapted to emit an infrared radiation according to one and the other of its faces, and maintained in suspension with respect to the support (400), the rear face (220) in line with and at a distance D from the wall (410); electrostatic actuating means (300) adapted to vary the distance D; the membrane (200) and the means (300) being laid out such that, for each wavelength, the infrared radiation emitted by the rear face (220) is reflected by the wall (410), passes through the membrane (200) and interferes with the infrared radiation emitted by the front face (210).

Abstract: The invention relates to an infrared device comprising a resistive element suspended in a cavity formed in a main element, and capable of transmitting infrared radiation when it is fed with an electric current. In particular, the main element is at least partly covered on the outer surface thereof and/or the inner surface thereof with a reflective coating. The use of the reflective coating makes it possible to at least partly contain infrared radiation transmitted by the resistive element in the cavity.
