Precise testing of asymmetric wavefronts with an inverting interferometer.
The procedure is described for increasing the precision of the method of testing the asymmetrical aberrations with an inverting confocal Fabry-Perot interferometer. The appropriate choice of the registration plane of the interference pattern and subtraction of respective wavefronts (obtained with a changed sign of asymmetrical wave aberrations) make possible testing of aberrations with a sensitivity of the order of lambda/50. The experimental results are discussed. The use of the method proposed to control the centering quality of the optical systems or elements is described.
