Tn. Bezmenova et al., CONSTRUCTION AND TESTING OF HIGH-SPEED LATERAL SHEARING INTERFEROMETERS BASED ON THE IT-183 AND IT-228 INSTRUMENTS, Soviet journal of optical technology, 60(5), 1993, pp. 346-348
This paper shows that the IT-183 and IT-228 lateral-shearing mirror in
terferometers, operating with low-coherence light sources, have seriou
s limitations in terms of speed and sensitivity. A modernization of th
ese instruments has been carried out in order to eliminate these restr
ictions. Laboratory and full-scale tests of the modernized interferome
ters have shown that their speed and sensitivity were increased by one
and by two orders of magnitude, respectively, compared with the origi
nal instruments.
