An infrared-detecting device, includes an infrared detector configured to emit a signal representative of the thermal radiation of a hotspot, and a light source configured to emit an incident beam, preferably in a window of UV or visible wavelength. The infrared-detecting device furthermore comprises a synchronizing device connected to the light source and to the infrared detector or to the processing module, and configured to emit a synchronization signal, the infrared detector being configured to be activated in a preset time window depending on said synchronization signal.

Infrared detection device

An optical detection device includes a light source emitting a light beam whose electromagnetic field, a means adapted to divide the beam into a first beam defining a first reference pathway and a second beam defining a second sample pathway, a modulation system frequency-shifting the electromagnetic fields of the two beams, a beam coupler adapted to collect the beams, an optical detection system adapted to detect the signal arising from the interference between the beams and coupled via the coupler, the sample being placed in the sample pathway, the optical detection system comprising an optical detector and a device adapted to measure the amplitude and the phase of the signal, an opaque screen comprising an optical aperture is placed at the level of a zone of a sample, in proximity to the sample, in the sample pathway.
