Paper Abstract

Laser-aided spherometer is a novel designation for a flexible and high performance instrument to the measurement of curvature radii of spherical surfaces. Combining the well established technique of Laser interferometer for linear displacement measurement with the principle of a classical spherometer frame, an accuracy of one order of a magnitude better than current type of precision interferometers is reached. This stays as the first mark on the development of an all-optical high precision spherometer.
