Title: Measuring device for refraction extent
Inventor: KOBAYAKAWA YOSHI
IPC: G01M11/02
Filed: 1983-03-28
Abstract: PURPOSE:To solve a secondary curve equation, specify an ellipse connecting coordinates of five points, and calculate the extent of refraction in a longitudinal direction, by irradiating different positions of an optical element to be measured with at least five light beams, and photodetecting beams passed through it by optical position detecting element in two dimensions. CONSTITUTION:Five light beams 5a-5e are refracted through the optical element 1 to be measured to strike the two-dimensional optical position detecting element (cylindrical spherical lens in general) 3 such as a CCD through a photodetecting lens 2. When the optical element 1 to be measured is seen in the direction of the optical axis 4, the light beams 5a-5e are parallel to the optical axis 4. When the optical element 1 to be measured is a cylindrical spherical surface lens, the light beams 5a-5e are on the circumference of the ellipse. Then, a general secondary curve equation is solved from light beam positions to find the ellipse, obtaining the refractive value of the cylindrical spherical surface lens. The position of the center point 6 of the ellipse shows the degree of eccentricity to the optical axis 4 of the cylindrical spherical surface lens to obtain alignment information. Consequently, the extent of refraction in each longitude direction is calculated.
