## Abstract

Provided is a simulator device allowing simplification and cost minimization. A simulator device that generates and emits, to a LiDAR shining a laser light at a plurality of scanning locations, a false light corresponding to said laser light, and comprises: a light focusing unit that focuses the laser light shined at the plurality of scanning locations; and a simulator that, in accordance with the laser light focused by the light focusing unit, generates the false light resembling scattered light that is produced in a prescribed location, and emits the false light to the LiDAR via the light focusing unit.

## Claims

### Claim 1

A simulator device for use with a LiDAR that illuminates a plurality of scanning positions with laser light, the simulator device generating false light corresponding to the laser light and emitting the false light to the LiDAR, the simulator device comprising:
condenser units configured to collect the laser light emitted to the plurality of scanning positions; and
a simulator configured to generate, in correspondence with the laser light collected by the condenser units, the false light simulating scattered light produced in a given position, and to emit the false light to the LiDAR through the condenser units,
wherein the simulator includes
one light source that generates the false light,
one reflecting mirror that reflects the false light generated by the light source onto the condenser units,
a mirror drive unit that rotates the reflecting mirror, and
a controller that controls an operation of the light source and an operation of the mirror drive unit so that the false light enters the condenser units.

### Claim 2 (depends on 1)

The simulator device according to claim 1, further comprising optical members configured to diverge the false light,
wherein the simulator emits the diverged false light to the LiDAR through the condenser units.

### Claim 3 (depends on 1)

The simulator device according to claim 1, further comprising a light absorbing material configured to absorb the laser light at scanning positions where the laser light is not scattered.
