Example Application of Scanning Mirrors,Micromachining technology can enable a new generation of portable projection-video displays that are lower in weight, power consumption, and cost than displays that are available today. Emerging micromachined projection video display technologies fall into three general categories:shrill 发表于 2025-3-23 16:57:25
Surface-Micromachined Mirrors,e free-standing mechanical structures. Surface micromachined devices were made in the late 1960’s by Nathanson , and the foundations for the polysilicon surface-micromachining process were laid by Muller and Howe in 1982 . Steps in the fabrication process include, but are not limited to:确定无疑 发表于 2025-3-23 19:30:46
Introduction,ions, information display, and metrology. The advances in optical science at the beginning of the 20. century laid the foundation for the understanding of optical particle and wave properties, and in the 1950’s the invention of the laser allowed, for the first time, practical commercial and industri只有 发表于 2025-3-24 00:33:02
Scanning Mirrors,statically. Resonant scanning — moving the mirror sinusoidally at its resonant frequency — is useful in such applications as line-scanning for barcode readers, raster-scanned video displays, and laser printers. Steady-state beam steering — moving the mirror from one static position to another — is u使乳化 发表于 2025-3-24 05:07:14

Staggered Torsional Electrostatic Combdrive (STEC) Micromirror, the Bosch process (65]. This process enables etching of trenches in silicon with aspect ratios up to 100:1. This deep-trench-etching process provides a hybrid between surface micromachining, as described in Chapter 3, and traditional bulk micromachining, where wet chemical etching is used to make santidepressant 发表于 2025-3-24 13:37:53
Conclusions,on, and reliability. These mirrors can offer significant advantages over macro-scale mirrors, but the fundamental limitations of scanning mirrors have not been widely discussed. In this dissertation we have derived the range of performance, in terms of resonant frequency and optical resolution, thatDUST 发表于 2025-3-24 15:49:30
