Title: LIGHT CONTROL DEVICE FOR INFRARED REGION AND VISIBLE REGION
Abstract:
The present invention provides a light control device whereby light in the infrared region and light in the visible region at the time of incidence thereof can be emitted each with different polarization on a detection side thereof, and light quantity of the light can be controlled by the polarization thereof. Specifically, the present invention provides a light control device including at least one polarizing plate having polarization performance for light in the infrared region, at least one polarizing plate having polarization performance for light in the visible region, and a medium having a phase or a medium capable of phase control, the light control device converting incident light in the infrared region and incident light in the visible region each into different polarized light and thereby controlling transmitted light in the infrared region and transmitted light in the visible region.
