title: Modified-triggered photocounting and its application to optical superheterodyne spectrum analysis.
abstract: The characteristics of the modified-triggered photocounting rate of photoelectric pulses, counted up and down at a certain frequency after a pulse has occurred, were studied. It was found that the counting rate is equal to the magnitude of photocurrent passed through a narrowband filter whose middle frequency is the up-down counting rate. From this result, a new spectroscopic method is proposed employing the photocounting technique.
