摘要
Measurement device and methods for the detection and/or analysis of fluid-borne particles. The measurement device comprises a means for producing a flow of fluid along a fluid flow path, a laser positioned for emitting a beam of laser light in a measurement volume of the fluid flow path; a lens set for collecting laser light scattered in the measurement volume by fluid-borne particles contained in the flow of fluid; a multipixel photo-detector positioned for detecting scattered laser light collected by the lens set. The lens set is configured for focusing the scattered light in a line being perpendicular to a flow direction (y) of the flow of fluid and at a focal distance of the lens set. The multipixel photodetector is positioned at a distance from the focal distance of the lens set and oriented with its longitudinal axis parallel to the line.
