摘要

摘要自由曲面在光学元件和系统中的应用越来越广泛。因此,需要适当的测量技术来测量这些自由曲面进行验证。这项任务对大多数测量技术来说仍然是一个挑战。在本文中,我们提出了一种基于实验光线追踪的光学和其他镜面自由曲面的测量技术。该技术能够同时测量形状和中空间频率偏差。重点将放在传感技术和测量不确定度的设置。在描述测量技术的同时,给出了基于仿真的不同不确定度影响的估计。根据不确定度的影响对实验测量的结果进行评价。给出了一种评价的比较方法。

Characterization of specular freeform surfaces from reflected ray directions using experimental ray tracing
Abstract. The applications of freeform surfaces in optical components and systems are increasing more and more. Therefore, appropriate measurement techniques are needed to measure these freeform surfaces for verification. This task is still a challenge for most measurement techniques. In this paper, we propose a measurement technique for optical and other specular freeform surfaces based on experimental ray tracing. This technique is able to measure form and mid-spatial-frequency deviations simultaneously. The focus will be set on the sensing technique and the measurement uncertainties in the setup. As the measurement technique is described, an estimation of the influence of different uncertainties based on simulations is given. The result from an experimental measurement is evaluated in relation to the influence of the uncertainties. A comparison measurement for evaluation is given.

期刊介绍: Journal of Sensors and Sensor Systems (JSSS) is an international open-access journal dedicated to science, application, and advancement of sensors and sensors as part of measurement systems. The emphasis is on sensor principles and phenomena, measuring systems, sensor technologies, and applications. The goal of JSSS is to provide a platform for scientists and professionals in academia – as well as for developers, engineers, and users – to discuss new developments and advancements in sensors and sensor systems.
