    摘要: An image projection system projects an image on a projection screen having a phosphor for converting incident violet light into green light which, together with red and blue light, creates the image in full color. The screen includes an apertured mask having apertures filled with the phosphor, or a phosphor plate in contact with the mask and having lenslets extending through and past the apertures.

    摘要: A miniaturized electro-optical, retro-reflective scanning module. The module has a base, a first circuit board, and a second circuit board mounted substantially orthogonal to the first circuit board. The base supports a light emitter for producing a scanning beam and optical elements for directing and collecting light energy. The emitted beam reflects off a fold mirror onto a reflector mounted on a drive for oscillation. The oscillating reflector, in turn, redirects the beam onto an indicia being read. The reflected light is reflected off the oscillating reflector and directed to the collection mirror before reaching a detector. The detector included in the module senses light reflected from an indicia scanned by the beam. The reflector is driven by an electro-magnetiz driven system, including a flexure and an actuation arm.
