BIOLOGICAL LIGHT MEASURING INSTRUMENT AND BIOLOGICAL LOAD REACTION MEASURING INSTRUMENT

摘要

PROBLEM TO BE SOLVED: To perform accurate measurment by suppressing a decrease in reaction or an increase in reaction caused by the habituation to the stimulation of a subject.;SOLUTION: A control part 8 receives whether a period for applying load to a subject 20 or a period not applying load to the subject 20 is set to a random period or a fixed period, from a user through an input/output part 12 to register the same in a task table 11 as a measuring parameter. According to the measuring parameter registered in the task table 11, the period setting the random period is determined at random and load is applied to the subject from the stimulation device 21 to control a light source part 1, a locking amplifying module 6 and an A/D converter 7. The intensity of biological transmitted light of the subject 20 is measured and the measuring result is stored in a recording part 9. An analyzing part 10 analyzes the intensity of biological transmitted light stored in the recording part 9 and the analysis result is displayed on the input/output part 12.;COPYRIGHT: (C)2004,JPO
