Av. Lukin et al., MONITORING OF THE PHASE-RELIEF STRUCTURE OF DIFFRACTION OPTICAL-ELEMENTS WHILE IT IS FORMING, Soviet journal of optical technology, 60(9), 1993, pp. 620-622
The construction principles of equipment for monitoring the phase-reli
ef structure of diffraction optical elements while it is forming are d
escribed. The methodological bases for using the equipment, the result
s of tests of an operating prototype, and the optical characteristics
of phase-relief gratings obtained on different photographic materials
are presented.
