Abstract: A brightness enhancement article for conditioning luminance from a light source (18) in a viewing direction is provided. A prism surface side (44) collects light from the light providing surface (14), where, in one embodiment, the prism surface side (44) has a series of substantially parallel grooves (30) forming a series of longitudinal trapezoidal prism elements (38). Each trapezoidal prism element (38) has a face plane (46) disposed toward the light source (18) and first and second legs (34,36) extending back from said face plane (46), respectively, forming first and second base angles ? with the face plane (46), where both first and second base angles ? satisfy: 90 degrees<base angle ?<120 degrees.

Abstract: An apparatus for printing images including an illumination optics (75) that provides uniform area light is disclosed. A prism (370) is located at a first position and receives the uniform area light and refracts the light. A first reflective LCD modulator (90) modulates the refracted light on a site by site basis and reflects the first modulated light to a second position on a media plane. A motor (441) rotates the prism (370) around an axis parallel to the illumination optics to a third position. A second reflective LCD modulator (95) modulates the refracted light on a site by site basis and reflects the second modulated light to a fourth position on the media plane.

Abstract: An apparatus for printing images including illumination optics (75) that provides uniform area light is disclosed. A mirror (440) receives the uniform area light and redirects the light. A first reflective LCD modulator (90) modulates the redirected light on a site by site basis and reflects the first modulated light to a media plane. A motor (441) moves the mirror on a line parallel to the illumination optics. The mirror redirects the light to a second reflective LCD modulator (95). The second reflective LCD modulator modulates the redirected light on a site by site basis and reflects the second modulated light to the media plane.

Abstract: An apparatus for printing images including an illumination optics (75) that provides uniform area light is disclosed. A polarizing beamsplitter (80) receives the uniform area light and redirects a first polarization state of the light to a first reflective LCD modulator (90) which modulates the first polarized light on a site by site basis and reflects the first modulator light through the polarizing beamsplitter (80). A parallel plate tilted at a first angle spatially displaces the first modulated light along a first line normal to the polarizing beamsplitter (80). A print lens assembly (110) images the first modulated light to a first position on a media plane to print a first image. The parallel plate is moved to a second position (250) and a new image is printed.

Abstract: An apparatus for printing high resolution images on a photosensitive media (140) includes an array of LEDs (12) for forming a light beam uniformizing optics (45) and a condensor lens (70) which transforms the light beam to a telecentric beam. A polarizing beamsplitter (80) splits said telecentric beam into a first polarized beam and a second polarized beam and directs the first polarized beam to a first reflective LCD modulator (90) and directs the second polarized beam to a second reflective LCD modulator (95). The first reflective LCD modulator (90) rotates a first polarization state of the first polarized beam on a site by site basis to produce a first modulated polarized beam and reflects the first modulated polarized beam, in response to a first image data signal, through the polarizing beamsplitter (80).
