A novel method is presented to determine the optical scattering length in scintillator crystals by directly measuring the scattered light power. It enables to eliminate the large uncertainties in deriving scattering lengths from the measured transmit

Principal refractive indices of the biaxial cerium-doped LuxY2−xSiO5 (LYSO) crystal were determined with high accuracy at seven different wavelengths between 400 and 700 nm using the classical minimum angle of deviation method. The reliability of t

Crosstalk related raw signal-to-noise ratio (SNR) and bit error rate (BER) of high density bitwise microholographic data storage is investigated by numerical modeling. Scattering and diffraction of light is calculated in non-paraxial scalar approxima

Photoinduced anisotropy in azobenzene side-chain polymers are characterized in two ways, by numerical solution of the proper rate-equations and by approximate analytical expression. Feasibility of these methods was investigated by comparison with res

The saturation behavior of diffraction efficiency has been experimentally studied and theoretically modeled in azobenzene polyesters by recording polarization gratings with two beams of orthogonal circular polarization. The model is an extension of t

The temporal evolution of photoinduced birefringence is investigated on the basis of a model proposed by Pedersen and co-workers. This model is extended for the case of elliptically polarized light, and used to describe the erasure of photoinduced bi

In the recent years new digital photon counter devices (also known as silicon photomultipliers, SiPMs) were designed and manufactured to be used specifically in positron emission tomography (PET) scanners. These finely pixelated devices opened new op

We propose a simple and robust method for the recovery of phase data pages. We provide experimental proof of the concept and investigate its applicability to optical encryption and encrypted holographic storage. Finally we discuss a possible compact
