ITF仪器传递函数-它是什么，为什么它是重要的(ITF Instrument Transfer Function - What it is and why it is important)
很多年来，大家一直关注于光学元件表面的形状误差，但随着对光学系统性能需求的增加，控制中频特征（MSF）也变得同样重要。对于一些极高性能应用，需要严格控制MSF特性以减少光散射并提高光学效率。在校正形状误差方面非常有效的小工具确定性抛光技术也会将不期望得到的中频特征赋予光学表面。根据表面特性的频率和斜率，传统的干涉仪系统-非常适合测量表面形状-由于分辨率有限，无法测量和量化较高频率的表面特性。分辨率的缺失意味着更高的频率细节被过滤（见右图），并且在测量结果中可能根本不显示。这是仪器传输函数（ITF）的所在。激光干涉仪系统由于其自身的设计（光学设计，相机，波长）会衰减和过滤部分表面信息，决定了该系统的ITF （测量光学表面的空间频谱的能力）。Verifire HDX激光干涉仪系统具有高分辨率3.4k x 3.4k传感器和优化的光学设计，具有比任何商业上可获得的干涉仪系统更高的ITF，使其成为可靠测量和量化光学表面中频特性的宝贵工具。这为光学设计师们提供了一种新能力，可以自信地指定光学表面到更高精度，并定义ITF测试要求来达到系统性能目标。For many years the focus has been on shape errors on the surface of optical components, but as the demand for optical system performance has increased, controlling the medium frequency characteristic (MSF) has become just as important. For some very high performance applications, tight control of MSF characteristics is required to minimize light scattering and improve optical efficiency.Gadget deterministic polishing techniques, which are very effective in correcting shape errors, can also impart undesired MSF characteristics to optical surfaces. Depending on the frequency and slope of the surface features, conventional interferometer systems-which are well suited to measuring surface shape-are unable to measure and quantify surface features at higher frequencies due to limited resolution. The lack of resolution means that higher frequency details are filtered (see right) and may not show up at all in the measurement results.This is where the instrument transfer function (ITF) comes in. A laser interferometer system, due to its own design (optical design, camera, wavelength) attenuates and filters some of the surface information, determining the system's ITF (the ability to measure the spatial spectrum of an optical surface.) The Verifire HDX laser interferometer system, with its high resolution 3.4k x 3.4k sensor and optimized optical design, has a higher ITF than any commercially available interferometer system, making it an excellent choice as an interferometer system. higher ITF than any commercially available interferometer system, making it an invaluable tool for reliably measuring and quantifying the IF characteristics of optical surfaces. This provides optical designers with a new ability to confidently specify optical surfaces to higher precision and define ITF test requirements to meet system performance goals.
