    Abstract: The invention relates to a photon-detection method, including a step consisting of subjecting a photodiode (PD), made of a semiconductor material, to a polarization voltage (BV) such that an avalanche breakdown can occur, when a photon penetrates into the photodiode, in an avalanche-breakdown layer (AZ) extending in the semiconductor material up to a minimum and maximum depth (Pm, PM) so as to be reachable by photons (PH, PH1) having a wavelength between a minimum and maximum wavelength (lambdam, lambdaMu), and steps of comparing the amplitude of a signal (DS), output by the photodiode, with two threshold values (V1, V2), and, if the amplitude of the signal is between the two threshold values, deducing that the photodiode has received a photon having a wavelength between two threshold wavelengths (lambdaS1, lambdaS2) that are between the minimum and maximum wavelengths.

    Abstract: The illumination system has a plurality of light emitters (R, G, B) and a light­collimator (1) for collimating light emitted by the light emitters. Light propagation in the light-collimator is based on total internal reflection (TIR) towards a light-exit window (4) of the light-collimator. At least one light sensor (8) for optical feedback is placed outside the light-collimator and is arranged to receive light emitted by the light emitters exclusively through reflection at the light-exit window of the light-collimator. Preferably, the light sensor is placed substantially coplanar with the light emitters. Preferably, a side wall (35) of the light-collimator is provided with a protruding portion (9) for guiding the light reflected at the light-exit window of the light-collimator towards the light sensor. Preferably, the illumination system is provided with a reflector (12). Preferably, the illumination system comprises a holographic diffuser (17). Accurate sensing of the color mixing of light emitted by the illumination system is obtained.
