Claim:
1. A light polarization analyzer comprising: an excitation light source that emits an excitation light polarized in a predetermined direction to a sample to be measured; an image sensor comprising a plurality of pixels arranged in a one-dimensional manner or otherwise a two-dimensional manner so as to receive a measurement light generated from the sample in response to the excitation light; a polarization selector that is arranged between the sample and the image sensor, that comprises a plurality of pixels arranged in a one-dimensional manner or otherwise a two-dimensional manner, and that is configured such that each pixel receives a corresponding portion of the measurement light, selects the measurement light having a polarization direction that corresponds to a driving signal applied to the pixel, and supplies the selected measurement light to the image sensor; and a measurement control unit that supplies the driving signal configured as a cyclic signal having a first period T wherein the light polarization analyzer measures a polarization state of a corresponding portion of the measurement light for each pixel based on the corresponding data I
