Abstract:
1. An optical measurement apparatus for measuring an optical information of a sample by irradiating a single mode light to the sample dispersed in a liquid, which comprises: a light source portion that irradiates the irradiating light to the liquid; a light receiving portion that receives the optical information of the sample including the irradiating light transmitted through the liquid to generate a receiving light signal, under a condition in which the liquid is irradiated by the irradiating light of the light source portion in a state that a relative position of the sample to the irradiating light varies at constant speed; a measurement portion that measures attenuation and amplification of intensity of the receiving light signal according to the sample; and a control portion that analyzes at least one of a size, shape and internal structure of the sample from the measured signal.
