発明の名称 (英語) PHOTODETECTION DEVICE, PHOTODETECTION METHOD AND PROGRAM 新技術説明会
発明の概要(英語) Provided are: a photodetection device capable of establishing a phase-sensitive detection mechanism using electric processing, and quickly detecting faint light at a high degree of sensitivity by using a simple configuration; a photodetection method; and a program. This photodetection device includes: a light source unit for generating first pulsed light; a filter unit for allowing second pulsed light constituting a part of a frequency spectrum exhibited by the first pulsed light to pass therethrough, and reflecting third pulsed light constituting another part of the frequency spectrum exhibited by the first pulsed light; a phase modulation unit for phase-modulating the second pulsed light using a plurality of phases; a multiplexing unit for creating fourth pulsed light by multiplexing the third pulsed light and the second pulsed light which was phase-modulated by the phase modulation unit; and a detection unit for spectrally dispersing and detecting scattered light produced by irradiation of a target object by the fourth pulsed light. Furthermore, the photodetection device extracts the frequency spectrum of scattered light which is scattered on the basis of the second pulsed light which was phase-modulated by the phase modulation unit, from the frequency spectrum of the scattered light detected by the detection unit, by synchronization with the phase modulation by the phase modulation unit using a prescribed computation processing.
