SUSPENDED PARTICLE ANALYSIS DEVICE Russian patent published in 2022 - IPC G01N15/02 

FIELD: measuring technology.

SUBSTANCE: invention relates to measurement techniques, in particular to the analysis of suspended particles. The suspended particle analysis device contains a light source, a lens focusing a light beam into the particle flow region, a series of lenses and mirrors located in the path of the light beam, forming four holographic images of particles on a matrix of charge-coupled devices of a video camera, which are fed to a personal computer for processing, characterized in that a laser is used as a light source in the device, also the device additionally contains two separating prisms, three lenses and two mirrors, while lenses and mirrors, located in the path of the light beam, are installed so that the axis of the light beam at the output is directed to the region of the particle flow, and the lenses do not lie on the same axis, but at the same time pass through the counting region of the beam, where they intersect at a point in the plane of registration of the matrix of devices with a charge-coupled digital video camera.

EFFECT: increase in the information content of measurements for particles of complex shapes.
