Abstract: 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.

Abstract: A method for super-resolution fluorescence microscopy includes the following steps: provoking the stochastic activation of fluorescent emitters contained in a sample to be observed, and illuminating the sample with an excitation light beam having a wavelength suitable for inducing fluorescent emission from the activated emitters; and acquiring a sequence of fluorescence images by means of an imaging system comprising a matrix image sensor; measuring arrival delays of fluorescence photons relative to the pulses of the excitation light beam, with a spatial resolution allowing each photon to be associated with a set of pixels of the matrix image sensor. A device and computer program product for the implementation of such a method are also provided.
