20100295836 | PHASE MODULATING APPARATUS AND PHASE MODULATING METHOD - The present invention relates to a phase modulating apparatus capable of highly accurately and easily correcting the phase modulation characteristic of a reflective electric address spatial light modulator even when a condition of input light is changed. In the LCOS phase modulating apparatus, an input unit inputs the condition of the input light, and a processing unit sets an input value for each pixel. A correction value deriving unit determines a correction condition according to the condition of the input light. A control input value converting unit converts the input value set for each pixel into a corrected input value based on the correction condition. An LUT processing unit converts the corrected input value into a voltage value, and drives each pixel by using a drive voltage equivalent to the converted voltage value. | 11-25-2010 |

20130286453 | LASER EMITTING APPARATUS USING A BASIC HOLOGRAM AND A FOCUSING HOLOGRAM - A laser processing apparatus including a laser light source, a phase modulation type spatial light modulator, a driving unit, a control unit, and an imaging optical system. A storage unit that is included in the driving unit stores a plurality of basic holograms corresponding to a plurality of basic processing patterns and a focusing hologram corresponding to a Fresnel lens pattern. The control unit arranges in parallel two or more basic holograms selected from the plurality of basic holograms stored in the storage unit, overlaps the focusing hologram with each of the basic holograms arranged in parallel to form the whole hologram, and presents the formed whole hologram to the spatial light modulator. | 10-31-2013 |
