Abstract

PURPOSE: To detect the shape of light beam by the distribution of outputs of solid image pickup elements by applying the light beam to the elements array in which plural elements are arranged with a pitch sufficiently less than the diameter of measured part of the light beam.
CONSTITUTION: The solid image pickup elements array A consists of multiple elements i that are arranged in a row. The elements are made of photodiodes and charge bond elements and are arranged with a minute pitch sufficiently less than the diameter of light beam B. The distribution of outputs of respective elements can be obtained to know the sectional shape of beam B.
