Abstract
An artifact caused by secondary reflection is reduced. An imaging device according to an embodiment includes: a diffuser (110) that converts incident light into scattered light whose diameter is expanded in accordance with a propagation distance and outputs the scattered light; and a light receiver (132) that converts light diffused by the diffuser into an electric signal.
Claims15
An imaging device, comprising:
- a housing that includes:
- a light receiver;
- and
- a diffuser configured to:
- convert incident light into scattered light, wherein a diameter of the scattered light is expanded based on in a propagation distance of the scattered light,
- the diffuser is closer to a light reception surface of the light receiver than a surface of an inner wall of the housing, and
- the propagation distance corresponds to a distance travelled by the scattered light;
- and
- output the scattered light, wherein the light receiver is configured to convert the scattered light into an electric signal.
