OPTICAL SECTIONING OF SAMPLE AND DETECTION OF PARTICLES IN SAMPLE Russian patent published in 2014 - IPC G02B21/36 

FIELD: physics, optics.

SUBSTANCE: invention relates to an apparatus, a method and a system for analysing a nonhomogeneous liquid sample, which includes obtaining a plurality of images of said sample arranged relative to a sample device. The disclosed apparatus comprises at least a first optical detection assembly having an optical axis and at least one translation unit arranged to move the sample device and the first optical detection assembly relative to each other. The movement of the sample device and the first optical detection assembly relative to each other is along a scanning path, which forms an angle θ with the optical axis, wherein θ ranges from about 60 degrees to about 89.5 degrees. The disclosed method of analysing a nonhomogeneous liquid sample includes obtaining a plurality of images of said sample and comprises steps of arranging a sample relative to the sample device; arranging the sample device relative to said apparatus; moving the sample device and the first detection assembly relative to each other on the scanning length, wherein the movement includes movement in the direction along the first scanning path which forms an angle θ with the optical axis, where θ ranges from about 60 degrees to about 89.5 degrees, wherein electromagnetic waves are transmitted from an image illumination device through an imaging region in the direction of an imaging device and a plurality of images are obtained.

EFFECT: technical result of the disclosed group of inventions is illumination of a sample to transmit electromagnetic waves through an imaging region in a sample device to an imaging device to improve the device for obtaining a plurality of images of a nonhomogeneous sample.
