Abstract
1. Устройство для определения измерения изменения угловой координаты объекта в плоскости, содержащее точечный источник излучения, связываемый с контролируемым объектом, установленный по ходу излучения приемный блок, включающий в себя два плоских зеркала, расположенных на одинаковом расстоянии от источника, разнесенных в плоскости контроля и ориентированных так, что их нормали лежат в плоскости контроля и образуют углы 45° с направлением на источник, а отражающие поверхности обращены одна к другой, частичнопропускающее зеркало, нормаль которого также лежит в плоскости контроля и образует с направлением на источник угол 45° и контрзеркала, обращенного зеркальной поверхностью к плоскости измерения, отличающееся тем, что из устройства исключен один из оптических смесителей, а для обеспечения устранения неоднозначности отсчета используются две рабочие зоны каждого из входных зеркал, выбранные таким образом, что расстояния между соответствующими осевыми лучами пучков, падающих на эти зоны, относятся друг к другу как иррациональное число.2. Устройство по п.1, отличающееся тем, что приемный блок выполнен в виде склейки двух призм с нанесенными на ее грани отражающими и светоделительными поверхностями в соответствии с аналогичными поверхностями устройства по п.1.1. A device for determining the measurement of changes in the angular coordinate of an object in a plane, containing a point source of radiation associated with the object being monitored, a receiving unit installed along the radiation, including two plane mirrors located at the same distance from the source, spaced in the control plane and oriented so that their normals lie in the control plane and form angles of 45 ° with the direction to the source, and the reflecting surfaces face one another, partially transmitting mirror, normal it also lies in the control plane and forms an angle of 45 ° with the direction to the source and a counter-mirror facing the measuring plane with a mirror surface, characterized in that one of the optical mixers is excluded from the device, and two working zones of each input are used to ensure counting ambiguity mirrors chosen in such a way that the distances between the corresponding axial rays of the beams incident on these zones relate to each other as an irrational number. 2. The device according to claim 1, characterized in that the receiving unit is made in the form of gluing two prisms with reflective and beam-splitting surfaces deposited on its face in accordance with similar surfaces of the device according to claim 1.
