Holographic Optical Components Based on Photorefractive Crystals and Glasses: Comparative Analysis and Development Prospects

“…2. Holographic prisms based on multiplex Bragg gratings (more than 20 gratings recorded in a unit volume) for calibration of high-precision angle devices (jointly with Concern CSRI Elektropribor) [30].…”

Tunable two-beam interferometer with exact fixation of the interference pattern on a stationary photosensitive sample

“…Two-beam interferometers for recording holographic gratings are widely in demand in various fields of holography and photonics. For example, when studying the properties of photopolymer materials and holograms recorded in them [1,2], when creating holographic prisms in photorefractive materials by recording superimposed gratings [3], when recording arrays of Bragg gratings in optical fibers (FBG) as sensors of the physical state of the fiber [4] or inclined FBG [5] and in other applications, the tuning of the lattice period is important. In these cases, each tuning is carried out by changing the angle of convergence of the interfering beams (hereinafter partial beams -PBs), for which the alignment of the mirrors directing these beams to the photosensitive object (PSO) is performed, and the position of this object is corrected.…”
