A Straightness Error Compensation System for Topography Measurement Based on Thin Film Interferometry

Straightness error compensation is a critical process for high-accuracy topography measurement. In this paper, a straightness measurement system was presented based on the principle of fringe interferometry. This system consisted of a moving optical flat and a stationary prism placed close to each o...
