Abstract
УСТРОЙСТВО ДЛЯ ИЗМЕРЕНИЯ НЕПРЯМОЛИНЕЙНОСТИ ПЕРЕМЕЩЕНИЙ ОБЪЕКТОВ , содержащее лазер,измерительный канал с двум фоточувствительными датчиками и оптической све то делит ель ной системой ,св занный с исследуегФом объек- том , и схему обработки сигнала, отличающеес тем, что, с целью повышени точности измерений, оно снабжено опорным каналом, идентичным измерительному, опорный и измерительный каналы установлены последовательно по ходу светового луча, схема обработки сигнала выполнена в виде трех операционных усилителей, входы двух из которых подключены соответственно к выходам фотозлектронных датчиков измерительного и опорного каналов, выходы - к входам третьего операционного усилител , а фоточувствительные датчики выполСП нены координатно чувствительными. ffrA DEVICE FOR MEASURING THE INDIRECTNESS OF OBJECT DISPLACEMENTS, containing a laser, a measuring channel with two photosensitive sensors and an optical light separating the optical system, associated with a research object, and with the aim of improving the accuracy of measurements, it equipped with a reference channel, identical to the measuring, reference and measuring channels are installed in series along the light beam, the signal processing circuit is made in the form of three operational amplifiers, the inputs of two of which are connected respectively to the outputs of the photoelectric sensors of the measuring and reference channels, the outputs are connected to the inputs of the third operational amplifier, and the photosensitive sensors have not been coordinate-sensitive. ffr
