    摘要： An object of the invention is an image sensor comprising a matrix of pixels, extending along a detection plane, and configured to form an image of an incident light wave propagating in a spectral band along a propagation axis, the image sensor being characterized in that it comprises a mask, formed by opaque elementary masks, extending parallel to the detection plane, between which there extend openings through which the incident light wave can propagate toward the detection plane, the matrix of pixels being divided into: open pixels extending facing the openings; masked pixels, each masked pixel being defined by a projection of an elementary mask along the axis of propagation on the matrix of pixels, each masked pixel being associated with the elementary mask facing it; the image sensor comprising, between the open pixels and the openings: a waveguide, extending facing masked pixels and open pixels; a first diffraction grating, extending facing at least one open pixel, and configured to couple part of the incident light wave into the waveguide; a second diffraction grating, extending facing a masked pixel, and configured to extract part of a guided wave propagating in the waveguide.

    摘要： Provided is a particle counter including: a light source; a light superimposition unit configured to superimpose light beams; an irradiation optical system configured to irradiate a fluid in a flow passage with one of a plurality of light beams from the light source; a detection optical system configured to make a part of scattered light beams by a particle in the fluid enter the light superimposition unit; a reference optical system configured to split another one of the plurality of light beams into a plurality of reference light beams and makes the reference light beams enter the light superimposition unit; and a counting unit configured to count the particles on the basis of detection signals corresponding to an interference light beam received by a light receiver. The interference light beam is generated by interference between the scattered light beam and one of the reference light beams at the light superimposition unit, and is received by the light receiver corresponding to the reference light beam.
