photorefractive splicing device with double phase

Practical Uses and Applications of Electro
The phase modulator is the simplest electro-optic modulator.Here, an electric field is applied along one of the crystal's principal axes. 3 Light polarized along any other principal axis experiences an index of refraction change, hence an optical path length change, that is proportional to the applied electric field.

Selective Erasure of Holograms in Photorefractive and
A selective erasure/update method of multiplexed photorefractive and photopolymer holograms by use of the double Mach–Zehnder (DMZ) interferometric arrangement is proposed. The DMZ arrangement is used as the optical phase-control device for holographic recording/erasure/update operations, which can produce a pair of $pi$-phase-shifted interference patterns with a simple optical setup.

The spatial spectrum of angular phase matching for photorefractive devices that use orthogonally polarized reading and writing beams may be enhanced if the images are recorded at angles where the ordinary and extraordinary cross sections of the index ellipsoid have equal curvatures. Applications include holographic storage, phased-array radar processors, and achromatic photorefractive devices

We report on the operation of the double phase-conjugate mirror (DPCM). Two inputs to opposite sides of a photorefractive barium titanate crystal, which may carry different spatial images, are shown to pump the same four-wave mixing process mutually and are self-refracted without any external or internal crystal surface. This results in the phase-conjugate reproduction of the two images

The photorefractive properties of Sn2P2S6 crystals doped with Te and Sb in the near-infrared wavelength range up to 1064 nm are reported. The main photorefractive parameters, i.e., two-wave mixing gain, effective electro-optic coefficient, diffusion length, concentration of traps, and response time, are compared with conventional nominally pure Sn2P2S6. Te-doped Sn2P2S6 shows the fastest

LASIK
LASIK or Lasik (laser-assisted in situ keratomileusis), commonly referred to as laser eye surgery or laser vision correction, is a type of refractive surgery for the correction of myopia, hyperopia, and astigmatism. LASIK surgery is performed by an ophthalmologist who uses a laser or microkeratome to reshape the eye's cornea in order to improve visual acuity.

Conjugated Phase
The key element is a photorefractive BaTi0 3 phase conjugator that, at the same time, provides retroreflected phase conjugation, gain and thresholding. Due to the combined effect of gain and thresholding, only those signals strongly correlated with the partial object beam are emphasized.
