ABSTRACT:
A particle image analyzing apparatus including, a flow cell for enclosing a solution containing a particle to be analyzed in a sheathed flow to form the solution into a sample solution flow, an irradiation optical system for emitting light to irradiate the sample solution flow, a one dimension image sensor for receiving the light transmitted through the particle to scan the particle and output an image signal, an optical deflection device, including a variable deflection angle, for deflecting the transmitted light introduced to the image sensor, a controller for controlling the deflection angle of the optical deflection device such that the image sensor optically tracks the particle, and a signal processor for processing the output image signal of the image sensor to analyze the particle.
