ABSTRACT:
In order to measure the antigen-antibody reaction, a linearly polarized laser light beam is divided into first and second light beams and the first light beam is made incident upon a cell containing a reaction liquid including particles. The second light beam is phase-modulated by an optical phase-modulator with a phase-modulating angular frequency .omega..sup.0. A phase-modulated light beam emanating from the phase-modulator is made incident upon a photodetector together with light scattered by agglutinated particles via an analyzer having a polarization plane perpendicular to that of the linearly polarized light beam. An output signal of the photodetector is synchronously detected with a reference signal having a frequency of m.omega..sub.0 /2.pi., where m is a natural number.
