Paper Abstract

In this paper we show that interferometric systems with phase-conjugate mirrors (PCMs) the quantitative determination of the quality of optical elements (lenses, mirrors) and the measurement of optical wavefronts is possible with the same accuracy as with classical interferometric systems. With a view to a quantitative analysis we especially discuss the problem of applying an appropriate phase-shifting mechanism in an interferometer with a self- pumped phase conjugating mirror (SPPCM). Furthermore, we carried out first measurements of the accuracy of a Twyman-Green interferometer (TGIF) with SPPCM.
