摘要： A MEMS oscillating laser scanning unit (LSU) composed of a MEMS Control Module, a Pre-scan Module and a Post-scan Module is disclosed. The MEMS Control Module consists of a laser source and a MEMS oscillating mirror. The laser source and the MEMS oscillating mirror both are aligned with the same side, opposite to target surface so that laser beam emits from the side of the target surface, reverses by a reflection mirror of the Pre-scan Module and then moves along a plane formed by a central axis as well as an oscillatory rotary axis of the MEMS oscillating mirror, enters center of the MEMS oscillatory mirror. Thus, scanning spots on the target surface are all symmetrical to the central axis. Thus effective area of the MEMS oscillating mirror is reduced and further reduce the cost as well as improve scanning efficiency. Moreover, design of the fθ Lens is simpler and the volume of the LSU is reduced.

摘要： A laser scanning unit mainly includes a semiconductor laser, a collimator, a micro electronic mechanic system (MEMS) oscillatory mirror, and an fθ lens or an f sin θ lens. The MEMS oscillatory mirror is disposed between the collimator and the fθ lens to replace a conventional rotary polygonal mirror for controlling a direction in which laser beams are projected from the oscillatory mirror to the fθ lens. With the MEMS oscillatory mirror, the cylindrical lens may be omitted from the laser scanning unit and noises produced by the polygonal mirror rotating at high speed may be avoided. Moreover, the MEMS oscillatory mirror allows bi-directional scanning to therefore enable increased scanning frequency, simplified structure, and improved scanning efficiency.
摘要翻译：激光扫描单元主要包括半导体激光器，准直仪，微电子机械系统（MEMS）振荡镜，以及ftheta透镜或fsinθ透镜。 MEMS振荡镜设置在准直器和透镜之间以替代传统的旋转多面镜，用于控制激光束从振荡镜投射到透镜的方向。利用MEMS振荡镜，可以从激光扫描单元中省略柱面透镜，并且可以避免由高速旋转的多面镜产生的噪声。此外，MEMS振荡镜允许双向扫描，因此能够增加扫描频率，简化结构，提高扫描效率。

摘要： An in-line laser scanning unit (LSU) with multiple light beams is disclosed. The LSU includes a minimized in-line mirror set composed by a plurality of vertically stacked Micro Electronic Mechanical System (MEMS) oscillatory mirrors and a linear corresponding scanning lens set formed by a plurality of F-Sin θ lens stacked vertically so as to correct the variation of reflective angle of the oscillatory mirror that is sinusoidal in time. Thus the scanning speed of multiple laser beams on the image plane is constant. Therefore, the volume of color printers is effectively reduced and the scanning efficiency is improved when the LSU in accordance with the present invention is applied to the optical engines of color printers.

摘要： A lens displacement mechanism using shaped memory alloy (SMA) applied to an auto-focusing lens module is disclosed. The lens displacement mechanism comprising at least one SMA wire. Two opposite ends of the SMA wire are fixed and a longitudinal mid-point of an intermediate movable portion between the two opposite ends is tightened and is fixed on a corresponding hook disposed on an outer edge of the lens so that the intermediate movable portion is tightened between the two opposite ends. When the SMA wire is heated, the intermediate movable portion contracts to pull the hook of the lens for driving the lens to move and slide along with an optical axis so as to achieve auto-focus control. The present lens displacement mechanism is simple in structure and reflow process. Therefore, the present displacement mechanism is suitable to be used in portable camera or mobile phone or PDA, which needs to be small and have easily mass production by SMT.
