摘要

多边形扫描仪在光栅扫描成像方面具有最快的线速率。然而，由于光学不变性的原因，行速率与每行可分辨点数之间需要权衡。在此，我们介绍一种能在不牺牲速度的情况下增加镜像扫描仪每行可分辨点数的装置。我们首先从理论上模拟了该装置对多边形扫描仪每行可分辨点数的影响，然后用简化的面系统和使用多边形扫描仪的透射显微镜对该装置进行了实验测试。我们证明，在不降低空间分辨率的情况下，视场提高了 1.7 倍。

Improving the scan throughput of polygon scanners.

Polygon scanners allow for some of the fastest available line rates for raster scanning imaging. Due to the optical invariant, however, there is a trade-off between the line rate and the number of resolvable points per line. Here, we describe a device that can increase the number of resolvable points per line of mirror-based scanners without sacrificing speed. We first theoretically model the effect of the device on the number of resolvable points per line of a polygon scanner, and then experimentally test this device with both a simplified facet system and a transmission microscope using a polygon scanner. We demonstrate an improvement in the field of view by 1.7 times without a reduction in spatial resolution.
