Title:
プログラム可能なレーザー照明標示装置
Document Type and Number:
Japanese Patent JP2007506156
Kind Code:
A
Abstract:
A self-contained sign, illuminated by laser or other source of substantially parallel beams, presenting intensely lighted and vividly colored displays, is programmable to display one or more user designed images through controlled deflection of projected beams. The sign comprises a backlit illuminated apparatus of low depth to display dimension ratio, astigmatically correcting distortion of the projected dot resulting from oblique projection angles, such correction occurring in the projected beam's light path prior to controlled beam deflection. Embodiments further normalize obliquely incident light by employing a transmissive refractive right angle structure. Distortion of a projected image is minimized by appropriate pre- or post-processing of display data. Embodiments enable animation of images and are adaptable to networked control.
