    • The invention uses optics and precision mechanisms to quantitatively assess the performance of medical endoscopes. By viewing standardized optical targets under well-controlled conditions, the optical quality of endoscopes can be easily determined in much the same fashion as getting one's eyes tested at the optometrist. The actual design, however, is much more complicated than your optometrist's eye chart and different types of endoscopes from different manufacturers require customization of the target geometry, the viewing distance, and the viewing angle. Also, there are several optical characteristics beyond image sharpness that need to be assessed, requiring other unique test geometries, including contrast, distortion, and vignetting. Clinically significant measurements are performed with simplicity and cost-effectiveness through the use of relatively inexpensive optical components and an embedded processor and graphical display system.
    • 本发明使用光学和精密机构来定量评估医用内窥镜的性能。 通过在良好控制的条件下观察标准化的光学目标,可以以与验光师测试眼睛大致相同的方式容易地确定内窥镜的光学质量。 然而,实际设计比您的验光师眼图复杂得多,不同制造商的不同类型的内窥镜需要定制目标几何,观看距离和视角。 此外,除了图像清晰度之外,还需要对其进行评估,需要其他独特的测试几何,包括对比度,失真和渐晕等几种光学特性。 通过使用相对便宜的光学元件和嵌入式处理器和图形显示系统,以简单和成本效益来进行临床重要的测量。
