The distance from the mirror's vertex to the center of curvature is called the radius of curvature, R. The focal length is half the radius of curvature and is as {eq}f=\frac{R}{2} {/eq}, where f is the focal length, and R is the radius of curvature. Convex and Concave Mirrors...
A procedure for the measurement of focal length and radius of curvature of a lens using coherent gradient sensing system and Fourier transform fringe analysis technique has been demonstrated. Light from the laser illuminates the specimen and the wavefront emerging from the specimen is tested using ...
