The goal of our project is to develop a rewritable holographic memory card system based on thin film polymer media. The data is stored in form of polarization Fourier holograms that present high efficiency even for thin material. The present communic

Phase-mostly modulation mode of a Sony LCX016AL-6 liquid crystal display has been found for appropriate elliptical polarization states of the input and output light with calculation using Jones matrices. Phase delay measurement with an accuracy of 2

Polarization holographic read/write and read only demonstrator systems have been developed using ~2 µm thick azobenzene polyester on a card form media. The thin-film holographic system has practical advantages, e.g. high diffraction efficiency, no c

We present the improved demonstrator of our rewritable holographic memory card system. High density optical storage is realized in a non-commercial optical set-up. Fourier transformed recording is used in a polarization holographic arrangement realiz

Optical storage properties of thin azobenzene side-chain polyester films were examined by polarization holographic measurements. The new amorphous polyester film is the candidate material for the purpose of rewritable holographic memory system. Tempo

We are developing a holographic memory card drive using thin polymer storage layer on credit card sized plastic carriers. The main features of the card are high storage density, re- writability and resistance to harsh environment (e.g. electromagneti

We introduce a new physical model for description of thin polarization holograms recorded and reconstructed with complex reference beams. Next we apply this model for two fundamentally different arrangements supposed to be used in a data storage syst

We developed a standard credit card-shaped general-purpose data carrier, a reflective Holographic Memory Card (HMC), and the appropriate equipment for its handling. Data recording and retrieval are accomplished by polarisation Fourier holography usin

In most optical storage methods data bits are stored in the form of microscopic pixels on the surface of an appropriate storage material. Some currently developed techniques apply parallel data processing by multiple data bit access simultaneously. S
