Abstract
A system includes a light source configured to emit pulsed laser light, and a photodetection unit including a plurality of photoelectric conversion units arranged in a two-dimensional plane, wherein an emission timing of the light source and a detection timing of the photodetection unit are controlled by a timing control unit, wherein the photodetection unit detects scattered light on the two-dimensional plane, of the pulsed laser light emitted from the light source and entering an object, and wherein change of a refractive index of the object is estimated from change of light speed of the scattered light.
