摘要

Problem to be solved: to grasp the distribution of the quantum efficiency at a predetermined surface of the sample, and to analyze the property of the sample in detail.A method of obtaining a quantum efficiency distribution on a predetermined surface of a sampleThe excited light belonging to the first wavelength region is irradiated on the reference material (standard white plate).By a photographing apparatus (camera module) having at least a first channel corresponding to at least a first wavelength region and a second channel corresponding to a second wavelength regionThe irradiation luminance value of the first channel of each pixel taken by the reference material and the irradiation luminance value of the second channel are obtained.The surface of the sample is irradiated with excitation light.By the photographing deviceThe measured luminance value of each channel of each pixel photographed with a predetermined plane is obtained.The absorption luminance value is calculated from the difference between the first and second channels.The fluorescence intensity value is calculated from the difference between the illumination luminance value of the second channel and the measured luminance value of the second channel.Calculates the quantum efficiency of each pixelThe quantum efficiency distribution at the predetermined surface of the sample is obtained.Diagram
