摘要： A hologram polarized light separator which does not generate heat when absorbing an unnecessary polarized component, does not degrade, has a high degree of separation, is lightweight, and allows a system to be of a small scale. Incident natural light (I) incident normally on the surface of a hologram (1) is separated into a first linearly polarized light (E1) traveling without being diffracted and a second linearly polarized light (E2) polarized perpendicularly to the direction of polarization of the first linearly polarized light (E1). The first linearly polarized light (E1) passes through a substrate glass (2) as it is; the second linearly polarized light (E2) undergoes internal total reflection at the glass-air boundary line and cannot go out to the output side of the separator. Therefore, the separator can allow only one of the polarized components of the incident natural light to travel in a predetermined direction. A liquid crystal projection display comprising the separator is also disclosed.

摘要： A polarized-light converting elemental device which can produce an accurately unidirectionally and circularly polarized light with a minimized loss of light and a projection-type display device using said unidirectionally-polarized-light converting elemental device are provided. A polarized-light converting elemental device comprises a mirror glass portion consisting of an array of mirror glass blocks each having a first reflecting optical element and a second reflecting optical element and a cholesteric-liquid-crystal glass portion including a cholesteric liquid crystal layer for reflecting either clockwise circularly polarized component or anticlockwise circularly polarized component and transmitting the other. Natural light from the left side is split into two directions by the first reflecting optical element. Light reflected from the cholesteric liquid crystal is reflected by the second reflecting optical element to alter its rotation direction and then transmitted through the cholesteric liquid crystal. The construction of the element can obtain outgoing light beams having the same rotation direction and propagate in two departing directions. A projection-type display device using the unidirectionally polarized light producing element is also provided (not shown).

摘要： A polarisation conversion system has a polarisation splitting element (16) for directing light having a first polarisation in a first direction and for directing light having a second polarisation different from the first polarisation in a second direction different from the first direction; and one or more polarisation conversion elements (19a,19b) for converting light having the first and second polarisations to light having a substantially common output polarisation. The polarisation separation element comprises a first array of prisms (20) having a wedge-shaped cross-section, and a second array of prisms (21) also having a wedge-shaped cross section. One of the prism arrays is an array of birefringent prisms. The polarisation conversion system may be used in a projection display system. An optical element comprises a substrate having a first lens array 17 on one surface and a second lens array 18 on the other surface of the substrate.

摘要： PROBLEM TO BE SOLVED: To provide an illumination device constituted so that the utlizing efficiency of light is enhanced and a bright projection screen is obtained by converting luminous flux shaped like a lamp reflector to the shape distribution of a rectangular display body by simple constitution and making it incident on the display body. SOLUTION: This device is constituted by being provided with a quadriangular pyramid type lens 3 having a rhombus-shaped bottom surface converting the luminous flux emitted from a lamp 1 and condensed by a reflector 2 to the shape distribution of the rectangular display body 4. The rhombus of the bottom surface of the lens 3 is formed so as to obtain the length ratio of a diogonal is the ratio of width: length = (b) : (a) when the side length ratio of the outside shape of the objective display body is the ratio of width : length = (a) : (b).
