Abstract
Provided is a sensor device including: a sensor unit that emits light and receives light reflected by an object; and a reflection mirror that is a columnar reflection mirror having a reflection surface on a side face and is configured to be rotated on an axis of the reflection mirror as a rotation axis, in which at least a part of the reflection surface forms a logarithmic spiral having the center at the rotation axis in a cross section perpendicular to the rotation axis, and when light emitted from the sensor unit and reflected by the reflection surface moves in parallel in response to rotation of the reflection mirror, the light reflected by the reflection surface is swept.
