Filed: 1996-06-26
Abstract: PROBLEM TO BE SOLVED: To perform a more precise detection without erroneously detecting an extremely thin irregularity as defect by extracting a defect candidate from the luminance change of an image data, and judging whether it is a defect or not from two images processed in time series. SOLUTION: A prescribed brightness pattern is projected on a surface 1a to be inspected by a lighting means 2, its image is taken by an image pickup means 3, and the brightness pattern is converted into an image data of electric signal. An image processing means 4 extracts, from the image data, only a high frequency component of spatial frequency components, or a component which is a luminance changed part and has a level of a prescribed value or more as defect candidate. A tracking processing means 5 executes a prescribed processing by the means 4 every optional time while moving the surface 1a to be inspected, or at least either one of the means 2 and the means 3. It is judged whether the resulting two continued images processed in time series are fitted to a prescribed comparing condition or not, and the fitted defect candidate is judged as defect.

Patent JP-S6143819-A (JP)
Title: Phase comparator
Inventor: ITO TAKASHI
IPC: H03L7/08
Filed: 1984-08-07
Abstract: PURPOSE:To eliminate the fluctuation of a phase difference depending on the circuit state by generating a pulse whose pulse width is proportional between the phase difference of the 1st binary signal and the 2nd binary signal and in synchronizing with the 1st binary signal and generating a voltage signal proportional to the phase difference. CONSTITUTION:When the phase of a signal NRZ is advanced, the pulse width of a pulse P1 is large, and a voltage VPE of a signal PE rises. When the phase is retarded conversely, the pulse width of the pulse P1 is narrowered and the VPE falls down. A pulse with a prescribed pulse width synchronously with the pulse P1 is formed like a pulse P2 and the pulse P2 is added to the pulse P1 to eliminate a frequency component appearing in a smoothed voltage. Thus, even if a frequency fluctuation is caused in the pulse P1, the voltage of the signal PE is not fluctuated and an always accurate phase difference is detected.

A transmitted wave reflected from the reflecting plate 9 and transmitted again through the specimen 1 and a reflected wave not transmitted through the specimen 1 but reflected therefrom are received by the probe 8. Out of the reflected waves received, subsequently, a transmitted reflection echo of the transmitted wave transmitted twice through the specimen 1 through the intermediary of the reflecting plate 9 and a flaw echo of a reflected wave reflected from a flaw in the specimen 1 are taken separately from each other. By using the transmitted reflection echo and the flaw echo thus taken out, the flaw and the depth position of the flaw can be detected simultaneously.
