Since an imperfection can occur anywhere over the surface of a component of any size or even within an assembled system, measurement cannot take place until it has been found and located in the measurement area. Inspectors often prefer to retain insp

Although the microscope image comparator was designed for quantifying the severity of surface imperfections, its ability to measure luminosity values of any image and compare values with images of similar objects suggests there may be other uses for

The most economical way to inspect optical components for imperfections has been found to be by using the eye to collect the low-angle light they scatter. Attempts to automate this process have so far not succeeded due to considerations of sensitivit

The publication of a new ISO standard and the increasing need to tolerance the surface quality of laser components has created renewed interest in defining surface imperfection parameters. Assessment of the performance of conventional subjective meth

The functional and perceived quality of an optical component depend on both the global and localized nature of its surfaces. While small departures in specification of surface form, roughness, and waviness occur as global errors, extending over the w
