Abstract
Изобретение относитс к области гиро- скопии и может быть использовано дл измерени угловой скорости и пространственной ориентации движущихс обьектов. Целью изобретени вл етс повышение точности измерени угловой скорости. Цель изобретени достигаетс тем, что в лазерный гироскоп введены последовательно соединенные тактовый генератор 23 и лини задержки 24, а также высокочастотный переключатель 18 и вычислительный блок 25, первый 4 и второй 5 акустооптические элементы выполнены в виде чеек Брэгга и снабжены соответственно первым 16 и вторым 17 и третьим 14 и четвертым 15 преобразовател ми ультразвука, установленными на противоположных гран х звукопроводов чеек Брэгга Ячейки 4 и 5 выполнены в виде усеченных равнобедренных призм, а угол при вершине усеченной призмы определ етс выражением у л- 2arctgn, где п - показатель преломлени материала призмы 1 з п ф-лы, 3 ил.The invention relates to the field of gyroscopy and can be used to measure the angular velocity and spatial orientation of moving objects. An object of the invention is to improve the accuracy of measuring angular velocity. The purpose of the invention is achieved by the fact that a serially connected clock generator 23 and a delay line 24, as well as a high-frequency switch 18 and a computing unit 25, the first 4 and second 5 acousto-optical elements are made in the form of Bragg cells and are equipped with the first 16 and second 17, respectively and the third 14 and fourth 15 ultrasound transducers mounted on opposite sides of the sound ducts of Bragg cells. Cells 4 and 5 are made in the form of truncated isosceles prisms, and the angle at the apex is truncated of the prism is defined by the expression for l-2arctgn, where n is the refractive index of the prism material 1 s p-3, 3 yl.
