  • Publication number: 20220146402
    Abstract: A particle detector includes at least one resonant cavity partially formed at least by a first reflector, a second reflector disposed at a distance from the first reflector and a channel located between the first and second reflectors, the channel being intended to receive at least one fluid comprising particles and to receive at least one light radiation; and at least one detection system having at least one photodetector. The particle detector is configured so that a portion of the light radiation present in the channel escapes from the cavity throughout the second reflector and reaches the detection system, thereby enabling the at least one photodetector to detect leakage of the cavity. The second reflector is a photonic crystal membranes PCM based reflector.
