Light detection device

Abstract

The present technology relates to a light detection device capable of receiving light from an object to be measured without interference. The light detection device includes a Peltier element configured of a P-type semiconductor and an N-type semiconductor disposed between a first substrate and a second substrate, and a light receiving part configured to receive light from the object having been subjected to temperature modulation by the Peltier element, in which the first substrate is provided on the object side, the second substrate is provided on the light receiving part side, and at least parts of the first substrate and the second substrate are configured to transmit light from the object. The present technology can be applied to, for example, a detection device that detects a predetermined material by receiving and analyzing light from an object to be measured.
