Abstract
Лазерный измеритель непрямолинейности, содержащий лазер, оптическую систему, создающую стабильное базовое направление путем образования кольцевой структуры лазерного луча, и измерительный блок с позиционно-чувствительным фотоприемником, подключенным к вычислительному блоку, отличающийся тем, что оптическая система состоит из двух компонентов, первым из которых является отрицательная линза, а второй выполнен в виде аксикона с двумя сферическими поверхностями с радиусами R1 и R2, при этом , а в качестве фотоприемника установлена цифровая телекамера с возможностью регулирования коэффициента преобразования оптических сигналов в электрические, а вычислительный блок реализующий алгоритм приема сигналов выделенного кадра телекамеры и измеряющий координаты точки изображения с максимальной яркостью с последующим усреднением результатов измерений, выполнен с возможностью корректировки параметров телекамеры. A laser linearity meter comprising a laser, an optical system that creates a stable base direction by forming a ring structure of the laser beam, and a measuring unit with a position-sensitive photodetector connected to a computing unit, characterized in that the optical system consists of two components, the first of which is a negative lens, and the second is made in the form of an axicon with two spherical surfaces with radii R1 and R2, while, as a photodetector, a digital camera with adjustable conversion gain of the optical signals into electrical signals, and a computing unit implementing an algorithm of reception signals selected camera frame, and measures the coordinates of the image with the maximum luminance and averaging the measurement results is arranged to adjust the camera parameters.
