Изобретение относитс к измерительной технике и может быть использовано дл неразрушающего контрол материалов.The invention relates to a measurement technique and can be used for non-destructive testing of materials.
Известен способ возбуждени ультразвуковых колебаний ддт неразрушающего контрол , заключающийс в том, что ультразвуковые колебани возбуждают лазерным потоком, который предварительно оптически преобразуют путем последовательно рассеивани и фокусировки р J.A known method of exciting ultrasonic vibrations from a non-destructive test of a non-destructive testing consists in that ultrasonic vibrations are excited by a laser stream, which is preliminarily optically converted by sequentially scattering and focusing p J.
Недостаток известного способа состоит в малой производительности неразрушающего контрол из-за ограниченного управлени даграммой на ,правленности возбуждаемых УЗК.The disadvantage of this method is the low productivity of non-destructive testing due to the limited control of the drum on the board of the excited ultrasonic testing.
Целью изобретени вл етс повышение производительности неразрушающего контрол .The aim of the invention is to improve the performance of non-destructive testing.
Поставленна цель достигаетс тем, что согласно способу возб 7вдени ультразвуковых колебаний дл неразрушающего контрол , заключаюп;емс вThe goal is achieved by the fact that, according to the method of excitation of ultrasonic vibrations for non-destructive testing,
том, что ультразвуковые колебани возбуждают лазерным потоком, который предварительно оптически преобразуют, оптическое преобразование лазерного йотока осуществл ют делением на несколько параллельных пучков, каждый из которых подвергают оптическому раст жению и сжатию во взаимно перпендикул рных направлени х, а затем повороту.That the ultrasonic vibrations are excited by a laser stream that is pre-optically converted, the optical conversion of the laser beam is done by dividing it into several parallel beams, each of which is subjected to optical stretching and compression in mutually perpendicular directions, and then rotating.

На чертеже представлена схема реализации изобретени .The drawing shows a scheme for implementing the invention.
На схеме показаны лазер 1, оптический делитель 2, объектив 3 состо щие из сферических линз 4 и цилиндрических линз 5, рассто ние между которыми может регулироватьс ,сканирующие устройства 6 и изделие 7.The diagram shows a laser 1, an optical divider 2, an objective 3 consisting of spherical lenses 4 and cylindrical lenses 5, the distance between which can be adjusted, scanning devices 6 and product 7.
Способ заключаетс в следующем.The method is as follows.
Световой поток от лазера 1 дел т The luminous flux from the laser 1 is divided
20 в делителе 2 на несколько параллельных пучков, каждый из которых направл ют в объективы 3 в которых пучки подвергают оптическому раст жению и20 in divider 2 into several parallel beams, each of which is directed to objectives 3 in which the beams are subjected to optical stretching and
