Air flow turbulence orthogonality and surface error estimation in large aperture optical testing

Haixiang Hu et al.

Summary: With the development of large-scale SiC materials and CCOS, MRF processing technology, optical manufacturing has entered the era of giant mirrors. Surface testing technology, as the basis of all optical processing, is facing challenges of high efficiency, high precision, and high accuracy. In this study, a method to estimate the actual surface error from individual measurements was proposed and validated through experiments.

The instrument transfer function for optical measurements of surface topography

Peter J. de Groot

Summary: The Instrument Transfer Function (ITF) quantifies height response as a function of the lateral spatial frequency content of the surface for optical measurements of areal surface topography. This paper provides a comprehensive review of ITF, including standardized definitions, prediction methods, common uses, limitations, and evaluation techniques.
