Abstract

Изобретение относитс  к контрольно-измерительной технике. Цель изобретени  - повышение точности за счет точечного контрол  отклонени  поверхности. Устройство состоит из оптически св занных источника 1 излучени , разделител  2 пучка и координатно-чувствительных фотоприемников 3 и 4, измерительной платформы 6 и щелевого экрана 15. При перекрытии лучей от разделител  2 щелевым экраном 15 измерительна  платформа 6 перемещаетс  по сигналам от фотоприемников 3 и 4 до устранени  перекрыти . 3 ил.This invention relates to instrumentation technology. The purpose of the invention is to improve the accuracy due to the point control of the surface deviation. The device consists of optically coupled radiation source 1, a beam separator 2 and coordinate-sensitive photodetectors 3 and 4, a measuring platform 6 and a slotted screen 15. When the beams from the separator 2 overlap with a slotted screen 15, the measuring platform 6 moves along signals from photodetectors 3 and 4 until elimination of overlap. 3 il.
