A New Technique for Measuring Scotopic Critical Flicker Frequency to Indicate Psychophysiological Stress

摘要

The technique for measuring scotopic critical flicker frequency (SCFF) that has been described in this report was used primarily to study the effects of a simulated lunar magnetic environment on human subjects; no changes in SCFF occurred that could be attributed to the magnetic environment. The large volume of data accumulated clearly shows that SCFF can be measured with good reproducibility by this method.
