摘要	An adaptive alignment technique provides precise control and active positioning in two-dimensions of sub-millimeter-sized objects such as, a spherical microlens (1) through the application of electrophoretic forces in a microfluidic well (2). A microfluidic well (2) and electrodes (3) can be addressed to position or align the spherical microlens (1) to a corresponding beam source . The motion of the microlens is preferably controlled using CMOS compatible voltages that are preferably applied to opposite electrodes (3) in the microfluidic well (2). By applying voltages to opposed electrode pairs, movement of spherical microlenses with sizes ranging from,0.87 microns to 40 microns in directions parallel to the electrode surface is realized. Optical alignment of the spherical or ball microlens preferably accomplished by use of feedback from a photodetector serves to position the microlens for maximum efficiency. Microlenses or other elements may thus be aligned to optical fibers, VCSELs, LEDs, photodetectors, etc.
其他摘要	自适应对准技术通过在微流体孔（2）中施加电泳力，在亚毫米尺寸的物体（例如球形微透镜（1））的二维中提供精确控制和主动定位。可以寻址微流体阱（2）和电极（3）以将球形微透镜（1）定位或对准到相应的光束源。微透镜的运动优选地使用CMOS兼容电压来控制，所述CMOS兼容电压优选地施加到微流体阱（2）中的相对电极（3）。通过向相对的电极对施加电压，实现了在平行于电极表面的方向上尺寸范围为0.87微米至40微米的球形微透镜的移动。球形或球形微透镜的光学对准优选地通过使用来自光电探测器的反馈来实现，用于定位微透镜以获得最大效率。因此，微透镜或其他元件可以与光纤，VCSEL，LED，光电探测器等对准。
