DEVICE MEASURING PHYSICAL PARAMETERS, PREDOMINANTLY TEMPERATURE Russian patent published in 2002 - IPC

FIELD: measurement of temperature and displacement of object. SUBSTANCE: device incorporates several fiber-optical paths including two light guides, sensitive optical element placed between their butts, electron unit processing electric signals that has computer. Sensitive element contacts object under control and changes its spectral transparency under effect of measured parameters. Input sections of fiber-optical paths are installed in opposition to common radiation source and output sections of fiber-optical paths are placed opposite to common radiation detector. EFFECT: possibility to control parameters of object in several points simultaneously with use of single optical system. 6 cl, 8 dwg
