Abstract
A method based on the use of autodyne detection effects in a semicondu ctor laser is proposed to analyze the dynamic state of biological spec imens. The advantages of this method compared with conventional photoe lectric methods are demonstrated. Results are presented of the use of the proposed method to investigate the heart beat frequency and amplit ude of Daphnia as a function of the degree of toxicity of the aqueous medium.
