Description
после порогового устройства 9 регистрирует целое количество периодов разности хода. В пределах периода угол измер етс по стрелочному индикатору 8. Точка начала отсчета определ етс при совмещении автоколлимационного блика от поверхности зеркала 3 с сеткой трубы 11.after the threshold device 9 registers an integer number of periods of the difference in travel. Within the period, the angle is measured by the dial indicator 8. The point of origin is determined by aligning the autocollimation highlight from the surface of mirror 3 with the grid of the pipe 11.
Предлагаемое устройство позвол ет на пор док повысить точность измерени углов по сравнению с отсчетными устройствами теодолитов в диапазоне измерени углов ±60.The proposed device allows an increase in the accuracy of angle measurement in comparison with reading devices of theodolites in the range of measuring angles of ± 60.
Точность измерений не ниже 0,01-0,1Формула изобретени /The measurement accuracy is not lower than 0.01-0.1. The formula of the invention /
Устройство дл измерени углов, содержаш ,ее укрепленные на неподвижном основании источник излучени , пол роид, фотоэлектронный регистрирующий узел и установленную с возможностью поворота пластину из двулучепреломл ющего материала, отличающеес тем, что, с целью повыщени точности измерений, на неподвижном-основании по обе стороны пластины укреплены зеркала , а совместно с пластиной укреплена зрительна труба, часть апертуры которой в исходном положении закрыта одним из зеркал.A device for measuring angles, containing it, mounted on a fixed base, a radiation source, a polaroid, a photoelectronic recording unit and a plate of birefringent material installed with the possibility of rotation, characterized in that, in order to improve the measurement accuracy, on a fixed base on both sides the plates are reinforced with mirrors, and together with the plate the visual tube is strengthened, part of the aperture of which is initially closed by one of the mirrors.
