Abstract
Wavelength measurement is a critical topic in many applications. Stationary interferometers, such as Fizeau and Murty, can be successfully used, considering the proportionality between the wavelength and the fringe spacing in the interference pattern.In this work we present a 1D algorithm for the calculation of the fringe spacing and error sources. The final accuracy that can be achieved is also assessed. The experimental data are taken from fringe pattern recorded with a Murty interferometer.
