Photoresists. These are used in holography because they can be employed to map holographic exposures into surface relief. This property is utilised in the production of embossing masters, reflection and transmission gratings and in computer generated holograms. 

We have evaluated three different techniques to generate QSAR models, namely Comparative Molecular Field Analysis (CoMFA), Comprehensive Descriptors for Structural and Statistical Analysis (CODESSA), and Hologram QSAR (HQSAR). More specifically they were evaluated for their utility (predictivity, speed, accuracy, and reproducibility) to predict ER binding activity quantitatively (Tong et al., 1998 Shi et al., 2001). Common to the three QSAR methods is the... 

Measurements and information. The above-desoribed instrument can form images at 82 and 164 MHz with a signal bandwidth around 5 MHz. In order not to narrow such a bandwidth, the maximum number of lines or aros used must not exoeed 16. The microscope currently uses various oomputer-generated holograms to tailor the optical distribution on the sample surfaoe and is being converted to use an SLM. The stand-off distance from the optios to the sample is around 50 mm, whioh is determined by the need to resolve the SAWs at 164 MHz. 

Uniform preillumination is discussed in the literature in two different time regimes. Fast diffraction response is obtained from materials which are illuminated uniformly and intensely for a few seconds before a second writing beam is used to pattern the intensity in the material and begin hologram formation. This maximizes the mobile hole density in the material at the time of hologram formation and helps to reach the charge generation limit of Eq. (1).
