Title: Detecting method for position of focal point
Inventor: HOSOE HIDE
IPC: G01M11/02
Filed: 1990-07-03
Abstract: PURPOSE:To detect a focal point of a luminous flux with high accuracy by sampling a plurality of wave front aberrations obtained by changing the defocus amount, with weighting the aberrations in accordance with the size of the level, and detecting the focal point based on the sampling values. CONSTITUTION:While a Fizeau interferometer is moved around a vertex reflecting position, wave front aberrations are obtained form the Fizeau fringes at a plurality of moving points, namely, for a plurality of the defocus amount. A deviation from the ground line of the curved fringe is obtained at each point, and a standard deviation Wvms is obtained from the deviation. Among a plurality of wave aberrations, those not larger than a predetermined level are removed, and only the aberrations exceeding the predetermined level are sampled. More specifically, the minimum value Wmin of the wave front aberrations W is obtained on the basis of the interference fringes, and then only those exceeding 2<1/2> Wmin are sampled. In this manner, an approximate curve is obtained according to the method of least squares on the basis of the plurality of sampling values of the wave front aberrations exceeding 2<1/2> Wmin. The defocus amount corresponding to the minimum value of the approximate curve is detected as a focal point of the generated luminous flux.
