Asymmetrical fringe broadening in a Lummer-Gehrcke interferometer.
This paper analyzes the effects of random surface irregularities on the intensity distribution of a Lummer-Gehrcke plate interferometer. These surface defects are distributed asymmetrically about the plane of the L-G plate and are usually caused by scratches during its use. Calculations have been conducted for typical values of parameters, and results of some specific examples have been presented graphically.
