Abstract

PURPOSE: To make inspecting work rapid without using large memory by a method wherein comparison is made between the first sweeped signal which is gained basing on the standard pattern data and the second sweeped signal which is gained by sweeping inspected pattern.
CONSTITUTION: Illumination is made from the light source 2 to the reverse face of the inspected pattern 1 suhc as a reticle and the light receiver 4 receives transmitted surface light through the optical sweeper 3. At this process the optical sweeper 3 sweeps all surface of the pattern 1 referring the position of the moving stage of pattern 1, and the light signal is input to the lighr receiver 4 sequentially. The sweeped signal P which is obtained by the light receiver 4 converting the light signal into the electric signal is injected differential comparator 6 through the amplifier 5. On the another part comparator 6 receives sweeped signal D which is obtained from the pattern generator 7 refering the pattern 1. In addition to this, optical sweeper 3 is drived by the pattern generator 7 and syncronization between signal P and D is maintained. Thus by comparing two signal at differential comparator 6 the display 8 shows the result.
