Abstract
Transmitter that includes a light source, a spatial light modulator including a modulation part that modulates illumination light emitted from the light source, a first mirror that is arranged on a first optical path of the modulated light modulated by the modulation part and reflects the modulated light toward a first projection range, and a second mirror that is arranged on a second optical path of the modulated light modulated by the modulation part and reflects the modulated light toward a second projection range around the first projection range. The first mirror and the second mirror are disposed at positions deviated from an optical path of unnecessary light included in the modulated light.

A transmitter comprising:
- a light source;
- a spatial light modulator including a modulation part that modulates illumination light emitted from the light source;
- a first mirror that is disposed on a first optical path of modulated light modulated by the modulation part and reflects the modulated light toward a first projection range;
- and
- a second mirror that is disposed on a second optical path of the modulated light modulated by the modulation part and reflects the modulated light toward a second projection range around the first projection range, wherein
- the first mirror and the second mirror are disposed at positions deviated from an optical path of unnecessary light included in the modulated light.
