Title:
測距システム、及び、受光モジュール、並びに、バンドパスフィルタの製造方法
Document Type and Number:
Japanese Patent JP7229988
Kind Code:
B2
Abstract:
A distance measuring system includes a light source unit that emits infrared light toward a target object, a light receiving unit that receives the infrared light from the target object, and an arithmetic processing unit that obtains information regarding a distance to the target object on the basis of data from the light receiving unit, in which an optical member including a bandpass filter that is selectively transparent to infrared light in a predetermined wavelength range is arranged on a light receiving surface side of the light receiving unit, and the bandpass filter has a concave-shaped light incident surface.
