| 摘要 |
The present invention relates to a spatial optical modulator, more specifically to a temperature adaptive optical modulator using a heater. The spatial optical modulator according to an aspect of the present invention includes a substrate; a structure layer, a center part of the structure layer being located at a predetermined distance from the substrate; driving means, located on the center part of the structure layer and allowing the center part of the structure layer to move upward and downward; an upper reflection layer, located in an upper part of the center part of the structure layer and reflecting and diffracting an incident beam of light; a lower reflection layer, located on the substrate and reflecting and diffracting the incident beam of light by a stepped portion formed between the upper reflection layer and the lower reflection layer, below the structure layer; and a heater, located in an upper part of the structure layer and/or at a side part of the driving means and generating heat by a predetermined voltage.
