ABSTRACT:
Disclosed is an optical flow system wherein individual particles, which are sequentially suspended in a fluid flow, are irradiated at a detection zone with an excitation source to generate radiation signals, which in turn are dispersed by a concave reflection grating for subsequent detection and measurement. The radiation signals which are not dispersed from the grating but are reflected from the grating, are further reflected by a conjugate mirror to form a projected image of the detection zone suitable for viewing with a screen or eyepiece.
