Vp. Ivanchenkov et Dy. Stepanov, WORKING OUT THE DETAILS OF COMPLEX WAVE-FIELDS BY TUNABLE NARROW-BANDOPTICAL FILTERING IN TERMS OF APPARENT VELOCITY, Journal of optical technology, 63(10), 1996, pp. 780-785
Based on an analysis of the two-dimensional spectrum of a wave field r
ecorded on an optical transparency, a tunable narrow-band filter has b
een synthesized that makes it possible with high resolution to disting
uish the recorded waves in terms of apparent velocity in the zone wher
e they interfere. An estimate is given of the efficiency of the propos
ed method for working out the details of wave fields. (C) 1996 The Opt
