Abstract
An optical measurement system capable of suppressing noise and realizing more accurate measurement is provided. The optical measurement system includes a light source, an image sensor, and an optical system including a beam splitter that divides light from the light source into first light and second light. The optical system can configure a first optical system that records with the image sensor, a first hologram resulting from modulation of first light with second light while there is no sample, the second light being diverging light, and a second optical system that records with the image sensor, a second hologram resulting from modulation with second light, of light obtained by illumination of a sample with first light. The second optical system includes a restriction mechanism that restricts spread of the light obtained by illumination of the sample with first light to be kept within a predetermined range.
