DIAGNOSTIC MEASUREMENT SYSTEM Russian patent published in 2004 - IPC

FIELD: measurement technology. SUBSTANCE: diagnostic measurement system incorporates optical circuit with laser radiator, light-reflecting film, unit of optical prisms with photodetector ensuring heterodyning of reflected radiation and electric circuit converting optical radiation to measured information electric signals containing analog-to-digital converter and device recording and processing measured signals. Light-reflecting film includes embedded elements of spherical form and secures adaptive diagram of reflection, film is applied to vibrating surface of object which condition is diagnosed. Laser radiator, unit of prisms and light-reflecting film are positioned on one straight line. EFFECT: potential for detection of static changes and measurement of dynamic deformations, simplified design and enhanced functional reliability of diagnostic measurement system.3 cl, 1 dwg
