Sensitivity variation in two-center holographic recording.
An experimental study of variation of sensitivity with recording and sensitizing intensities in two-center recording is presented. The experimental results are in good agreement with the theoretical predictions. It is shown experimentally, for what is to our knowledge the first time, that the sensitivity is a function of the ratio of recording to sensitizing intensities and not the absolute int...
متن کاملSensitivity improvement in two-center holographic recording.
Persistent holograms are recorded with green light in LiNbO(3) crystals doped with Mn and Fe. The recording sensitivity is 20 times better than that obtained by recording with red light. Partial loss of persistence is caused by using green light for recording.
متن کاملLaryngeal High-Speed Videoendoscopy: Sensitivity of Objective Parameters towards Recording Frame Rate
The current use of laryngeal high-speed videoendoscopy in clinic settings involves subjective visual assessment of vocal fold vibratory characteristics. However, objective quantification of vocal fold vibrations for evidence-based diagnosis and therapy is desired, and objective parameters assessing laryngeal dynamics have therefore been suggested. This study investigated the sensitivity of the ...
متن کاملHigh Density Pcm Magnetic Tape Recording
The Bell & Howell Enhanced-NRZ recording reproducing technique for bit packing densities up to 40,000 per track inch is described in this paper. Utilization of the pulse code modulation format of Enhanced-NRZ achieves this high density with a bit error rate of one in ten million. Bell & Howell’s standard VR-3700B instrumentation tape recorder and wideband instrumentation recording tape are used...
متن کاملA simple high-speed recording colorimeter system.
The rapid and continuous increase in microbiological assays requested of the routine clinical laboratory has created physical problems by the sheer number of tubes involved. One of the major difficulties is associated with the reading of large numbers of cultures with conventional instruments. In those assays where it is the rate of growth that is being measured, eg, Lactobacillus casei folate ...
