Electron-optical image converters (EOIC) have been known to be useful in recording and investigating high-speed processes, nuclear physics experiments, automatic environmental control, medicine etc. In this paper the cathode ray tubes with the cathodoluminescent screen having a sufficiently high level of the radiation temporal coherence (particularly on the basis of rare-earth phosphors) are proposed to be utilized as devices for the dynamic data input into the holographic correlator for realization of TV signal recognition in real time. This approach allows combining both the radiation source and the spatial light modulator functions in one compact device.
This paper presents comparative analysis of electronics and different types of optical links for transmissions of results of measurements from a `hot' zone. This problem is important in high energy physics experiments with accelerators and in experiments with nuclear reactors. It is generally preferable to use an optical fiber link before the electronic link. We compare parameters of optical links with light emission diode and with semiconductor laser, with external and with internal modulation, for analogical and for digital signals. The specified demands are conditioned by bandwidth more than 108 Hz and distance less than 102 m. The design and results of measurements of the technical parameters of the optical links with light emission diode and with low-threshold semiconductor Ga-As microlaser are shown. The program of the radiation resistance testing of this equipment in framework of the `ENTOREL' project is also discussed.
The education system in USSR in opposite of USA education system have general goal to give young man the concrete speciality. Nevertheless in the last years this system is being changed and physical education become more broad and humanitarian.
A new concept of wideband spectrum analyzer taking into account
the influence of technical parameters of two-dimensional raster
scanning system on the analysis accuracy is described. The principal
parameters 1imiting the dynamic range of analyzer are determined. The
problems of the semiconductor lasers using as input modulator are
considered.
