Title:
光学測定装置及び光学測定方法
Document Type and Number:
Japanese Patent JP7021288
Kind Code:
B2
Abstract:
An optical measurement device includes a light detection element for detecting detection light including fluorescence generated from an immuno-chromatography test piece irradiated with excitation light and scattered light caused by the excitation light and having a phase equivalent to that of the excitation light, and a cancel circuit for processing a detection signal corresponding to the detection light. The cancel circuit removes a signal component corresponding to the scattered light from the detection signal on the basis of a phase difference between the fluorescence and the scattered light.
