Abstract
This apparatus includes a laser light source S2 which irradiates a spatial light modulator (SLM) 11 with a laser beam LR. Individual optical systems are arranged such that the laser beam reflected by the SLM 11 irradiates a region to be treated. When this configuration is used, the laser beam reflectivity can be made much higher than when a transmitting device is used. This allows high-efficiency laser beam irradiation. A predetermined pattern is written in the SLM 11, and this predetermined pattern is preferably a hologram pattern.
Claims7
A laser therapeutic apparatus for irradiating a region to be treated with a laser beam, comprising:
- a reflecting spatial light modulator which displays a predetermined pattern;
- a laser light source which irradiates said spatial light modulator with a laser beam;
- and
- an optical system so positioned that the laser beam reflected by said spatial light modulator irradiates the region to be treated.
