TLDR
In a multifaceted mirror scanner, a mirror attached to a carrier that is precisely positioned receives energy from a collimated beam of light and reflects this energy toward a predetermined target point.Abstract:
In a multifaceted mirror scanner, a mirror attached to a carrier that is precisely positioned receives energy from a collimated beam of light and reflects this energy toward a predetermined target point. The carrier is then deformed, such as by making a dimple near an edge where the mirror should be raised slightly, to deflect the beam so that the reflected image is precisely oriented on the target point.read more

Real-time ultra-high resolution image projection display using laser-addressed liquid crystal light valve
John A. Trias,John Marez +1 more
TL;DR: In this article, a high intensity projection light beam is reflected from the liquid crystal via a polarizing biprism and is modulated by the bi-refringent liquid crystal so that a corresponding image is displayed on the screen.
Patent
Adaptive resonant positioner having random access capability
TL;DR: In this paper, a positioning system including a sensor, a drive control and an actuator is presented, where the sensor senses a mirror 64 position and provides actual position signals to drive controller 54, which responsively adapts and applies drive currents to actuator 56.
Patent
Facet angle corrector for multi-faceted optical scanner
TL;DR: In this article, a multi-faceted rotating optical scanning system with facet angle corrector is proposed for reducing banding in images produced therewith, where the corrector consists of a corrector plate supporting a plurality of transparent discs, each one being positioned in advance of a different facet of a scanner.

Lithographic mask structure and device for positioning the same
Shibata Hirofumi,Yasuaki Fukuda +1 more
TL;DR: In this paper, a mask structure and a mask positioning device, adapted to execute accurate and quick positioning of a mask having a generally ring-like shape, are disclosed, which includes a supporting frame of a general ring-shaped shape and at least one flat surface formed by a mirror surface at a peripheral part of the supporting frame.
Patent
Light beam generation, and focusing and redirecting device
TL;DR: In this paper, an improved light beam generation and focusing device has been constructed and arranged to sequentially direct the at least one beam of light to at least two spaced locations on the surface plane.
