Laser Gyroscope Is 50 Years Old. Part II Optical gyroscopes still retain leading positions in the navigation systems and tactical targeting systems market. If in the low accuracy sensors market sector dominate MEMS sensors due to their low price and compactability, in the strategic navigation systems laser gyroscopes percent is large in spite of fiber-optic and micromechanical gyroscopes active competition. The article brings of an overview of laser gyroscopes market state.

Cooled Monolithic Arrays of Infra-Red Band. Batch Production Use Currently, for the operation within the range of 1.5–5.5 µm cooled photon detector arrays are widely used. In IR micro-photoelectronic technologies two types of photodetecting arrays are used: monolithic and hybrid. The results of environmental tests products afford ground for chossing the monolithic designs.

Using Si PM in the Sphinx Station UHE Neutrinos Detector Si PM new generation permits to achieve a high quality analog signal. Cosmic rays induced pulses can be simply distinguished by a Si PM. That’s why Si PM are used for ultrahigh energy cosmic rays registration.
