Infrared projector
First Claim
1. An infrared projector for projecting a two-dimensional infrared radiation distribution pattern, the infrared projector comprising:
- a micromirror device as an optical modulator for changing the direction of reflection by providing a plurality of mirrors and changing the direction of each of the plurality of mirrors independently;
a controller for controlling the direction of each mirror of the micromirror device;
an infrared light source for irradiating the micromirror device with infrared light; and
an infrared wavelength selection means for adjustably selecting the wavelength of infrared radiation incident on the micromirror device;
the controller also controlling the infrared wavelength selection means such that the infrared radiation incident on the micromirror device has a desired wavelength characteristic.

Abstract
To provide an infrared projector in which it is not necessary to develop arrayed elements radiating infrared radiation, a high temporal resolution and a high spatial resolution are made available, the simulation of a high-temperature body is made possible, the wavelength and luminance characteristics are controlled, a high contrast and a high simulation accuracy are made available, and so on. A micromirror device (6) as an optical modulator for changing the direction of reflection by providing a plurality of mirrors and changing the direction of each of the plurality of mirrors independently, a controller (7) for controlling the direction of each mirror of the micromirror device, and infrared light sources (8, 9, and 10) for irradiating the micromirror device with infrared light are provided.
