Abstract

PURPOSE:To detect an abnormal pattern of a reticle by a method wherein video- signals obtained by photographing the reticle are made binary, and compared with design pattern information dot-converted, the movement of a base and photographing are synchronized, and errors are automatically compensated. CONSTITUTION:The reticle 2 on an X-Y base 10 is irradiated by means of a light source 11, the light is projected to a solid photographing element 3a of a picture input portion 3, and a picture of x coordinates of the reticle is photographed. The positional slippage of the reticle is read from the quantity of movement in the both coordinate axis direction of the base 10 by means of a laser measuring portion 16 operated by instructions from a central arithmetic unit 15, and the positioning of fixed coordinates and continuous feed to designated coordinates are controlled 17 by the base feed information of the arithmetic unit 15. The quantity of slippage is made binary 4 through a compensation controlling portion 18 and a series-parallel converting transferring portion 20, the scanning of the sensor 3a is controlled 3b, and errors being accompanied by travelling of the base are compensated. Design pattern information dot-converted and the signals of the picture input portion 3 are read by means of the arithmetic unit 15 from a buffer memory 21, and compared, and an abnormal pattern is detected.
