Abstract
изобретение относитс к измерительной технике. Целью изобретени вл етс ,снижение погрешности измерений и расширение области применени . Излучение источника 1 фокусируетс линзой 3 и, пройд через свето- делительный элемент , вращаемый двигателем 5 а затем через диафрагму 6, сканирует зону расположени измер емого объекта 7 и, далее пройд линзы 9 и 11 и диафрагмы 8 и 10, попадают строго в одно и то же место чувствительной площадки фотоприемника 12. Изменение тока с фотоприемника 12 и значение опорного напр жени корректирующего фотоприемника 1 вл етс информативными сигналами , по которым путем их обработки определ етс диаметр объекта 7. Положительный эффект обеспечиваетс за счет ограничени помех, возникающих при переотражении излучени от оптических деталей и св занных с неравномерностью чувствительности фотоприемника , а также за счет обработки информативных сигналов, позвол ющей определ ть положение объекта как в продольном, так и в поперечном .направлени х . 5 ил. г toThe invention relates to measurement technology. The aim of the invention is to reduce the measurement error and expand the scope. The radiation from source 1 is focused by lens 3 and, having passed through a light-transmitting element rotated by engine 5 and then through diaphragm 6, scans the location area of the measured object 7 and then passed lenses 9 and 11 and diaphragm 8 and 10, fall strictly into one the same place of the sensitive area of the photodetector 12. The change in current from the photodetector 12 and the value of the reference voltage of the corrective photodetector 1 are informative signals by which the diameter of the object 7 is determined by their processing. By limiting the interference arising from the re-reflections of radiation from optical components and associated with the uneven sensitivity of the photodetector, as well as through the processing of informative signals, allowing to determine the position of the object in both longitudinal and transverse directions. 5 il. r to
