LIGHT CONDENSING UNIT, LIGHT CONDENSATION METHOD, AND OPTICAL DETECTION SYSTEM

摘要

Provided is a light condensing unit including a reflection member having a hollow dome shape a side wall of which is curved to be extended from a top portion toward a bottom portion, the reflection member having a mirror-finished inner surface, and a plurality of light irradiation members arranged around an outer wall of the reflection member and configured to irradiate an irradiation region of the top portion with light through a first opening portion formed in the outer wall. The reflection member includes a second opening portion formed in the irradiation region of the top portion, and a third opening portion formed in the bottom portion to face a light receiving lens of a light receiving unit, the light receiving unit being configured to perform a predetermined process on received light.
