IMAGING DEVICE, BIOMETRIC AUTHENTICATION DEVICE, AND SEMICONDUCTOR LASER
Document Type and Number:
WIPO Patent Application WO/2017/086033
Kind Code:
A1
Abstract:
Provided is an imaging device whereby imaging accuracy can be improved while cost and device size are suppressed. An imaging device (1) that comprises: a light source (2) that is a semiconductor laser that emits infrared light on an imaging target (5); a polarizing filter (3) that blocks light reflected from the surface of the imaging target (5) and transmits light reflected from the inside of the imaging target (5); and an imaging element (4) that receives the light that has been transmitted through the polarizing filter (3) and captures an image of the imaging target (5).
