Abstract

A method based on the use of autodyne detection effects in a semiconductor laser is proposed to analyze the dynamic state of biological specimens. The advantages of this method compared with conventional photoelectric methods are demonstrated. Results are presented of the use of the proposed method to investigate the heart beat frequency and amplitude of Daphnia as a function of the degree of toxicity of the aqueous medium.
