Abstract
An excitation light source emits excitation light to a target sample. An image sensor includes pixels arranged one-dimensionally or two-dimensionally, and receives measurement light from the sample according to the excitation light. A polarization selector arranged between the sample and image sensor includes pixels arranged one-dimensionally or two-dimensionally. Each pixel receives a corresponding portion of the measurement light, selects light having a polarization direction that corresponds to a driving signal applied to the pixels, and supplies this light to the image sensor. A measurement control unit supplies the cyclic driving signal having a first period T, and acquires data I, I, I, and Ifrom each pixel of the image sensor for each exposure time segment T=T/4 obtained by dividing the first period Tby 4.
