Title: Device and method for inspection
Inventor: KAJIYAMA KOICHI
IPC: G01B11/30
Filed: 1994-11-11
Abstract: PURPOSE: To provide a device and a method for inspection by which the defect in a specific area can be selectively and preferentially detected by selecting and designating an area to be inspected. CONSTITUTION: The output waveform SI of a sensor is compared with a fixed reference level Th and a binarized pulse train P1 is formed. Then another binarized pulse train P2 is formed by delaying the pulse train P1 by one cycle and the AND of the pulse train P2 with the pulse train P1 is computed. As a result, random components are eliminated from signals and a pulse train which only corresponds to a cyclic pattern on an object to be inspected can be obtained. In addition, when a pulse having the fixed time width corresponding to the width of an area to be inspected on the object is formed by triggering the pulse train and the pulse is outputted, the pulse can be used as a signal for selecting the area to be inspected. Therefore, only defects to be detected can be selectively detected.
