摘要： A Fresnel lens collimates a light modulated by an image signal and outputs a collimated light. A diffusion member diffuses the collimated light and outputs a diffused light. A driver continually moves the Fresnel lens or the diffusion member on a predetermined trajectory within a plane parallel with a screen. A spring member couples the Fresnel lens or the diffusion member with a casing, including a first deformation plane flexible in a first direction within the plane, and a second deformation plane flexible in a second direction substantially perpendicular to the first direction within the plane, while it is not flexible in a direction perpendicular to the plane.

摘要： An image display projector is provided so as to reduce scintillation. The image display projector comprises: an optical engine for emitting light according to an inputted imaging signal; a Fresnel lens disposed to receive the light emitted from the optical engine, for emitting the incident light as collimated one; a diffusion member, placed in front of the Fresnel lens in the light-traveling direction, for diffusing the collimated light emitted from the Fresnel lens; and a drive unit for moving either the Fresnel lens or the diffusion member, along a predetermined track (orbit), in a plane parallel to either the plane from which the collimated light or the diffused light is emitted. And then, the moving velocity of either the Fresnel lens or the diffusion member is at any moment larger than zero in any direction within the parallel plane.

摘要： A light diffusion element includes a light diffusion layer that contains at least two types of liquid crystal molecules each having a different light scattering characteristic defined by a voltage and a refractive index. A pair of electrodes sandwiches the light diffusion layer, an applying unit generates and applies a variable voltage to the pair of electrodes, and a voltage changing unit varies the voltage generated by the applying unit. The voltage changing unit varies the voltage such that each of the refractive indexes of the liquid crystal molecules in the light diffusion layer changes temporally.
