Active energy ray-curable composition and lens sheet

A random polarized light from a light source (305) can be changed into a linear polarized light by using a polarization beam splitter (303), a transmitting means (304) for rotating a plane of polarization at 90.degree., reflectors (308) and a first prism formed plate (302). Further, a beam width of the linear polarized light thus obtained can be reduced by using a reflecting surface (307) and a second prism formed plate (301).

Polarization forming optical device

An optical imaging device for projecting an image in a strip area, comprising a reflecting plate having a plurality of pairs of reflecting surfaces arranged on a flat surface and forming an array in a first direction parallel to a long direction of a strip image, and at least one cylindrical focusing lens or mirror having a focusing power directed only to a second direction perpendicular to the first direction. The pair of reflecting surfaces is composed of two flat surfaces which cross at about a .pi./2 radian, and the crossing line of two adjacent reflecting surfaces is perpendicular to the first direction. The reflecting plate projects the image component in parallel to the first direction and the cylindrical focusing lens or mirror projects an image component perpendicular to the first direction. The resolving power in the first direction of the obtained image is determined by the pitch length of the pair of reflecting surfaces.

Optical imaging device

An optical device for forming a linear polarized light by dividing a light beam from a light source into two linear polarized light components, and rotating a plane of polarization of one of the light components at 90.degree. to follow joining of both the light components. Further, a polarization beam splitter for dividing a light beam into two linear polarized light components is employed in such an optical device.
