LASER INTERFEROMETRIC FORCE CONVERTER ( VARIANTS ) Russian patent published in 1999 - IPC

FIELD: measurement of forces with use of laser interferometric principles. SUBSTANCE: laser interferometric force converter for measurement of unidirectional load is manufactured from one piece of material to minimize hysteresis and includes ground end made fast to fixed reference plane and metric end to apply load. Converter has basic flexural members separating its ground and metric ends, flexural amplification members, bracket of reflectors and backward reflectors, one of them being mounted on metric end and second one - on ground end of converter. Assemblage of mirrors for turn of beams and assemblage of reflectors testing spatial displacement are attached to bracket of reflectors. In agreement with second variant of invention assemblage of mirrors for turn of beams is attached to bracket of reflectors and lever reinforcing displacement is attached to flexural members, first and second backward reflectors are secured to it. EFFECT: high degree of precision, replication and resolving power of converter. 3 cl, 10 dwg
