Title: Surface-defect inspecting apparatus
Inventor: SUZUKI MOTOYUKI
IPC: G01N21/88
Filed: 1990-11-30
Abstract: PURPOSE:To make it possible to detect the presence or absence of a defect on a surface to be inspected accurately even for a work wherein the surface to be inspected is not flat by judging the presence or absence of the defect on the surface to be inspected of the work based on the detected amount of light. CONSTITUTION:The light is emitted from a laser 30 on a surface to be inspected S through a beam expander 31. The reflected light from the surface to be inspected S is cast on an electronic array shutter 34 through a Fourier transformation lens 32 and a half mirror 33. Then, the shutter 34 forms a space frequency mask based on the surface to be inspected S of a master work. Therefore, with respect to the normal work without a defect on the surface to be inspected S, the light does not reach an optical sensor 35. It is judged that there is no defect with a judging part 42 based on the fact. With respect to the work having the defect, the light reaches the optical sensor 35, and the judging part 42 judges the presence or absence of the defect in correspondence with the degree. In this way, the defect can be detected highly accurately even for the work wherein the shape of the surface to be inspected S is not flat and the reflectivity of the surface is partially changed.

Filed: 1988-12-28
Abstract: PURPOSE:To improve reliability by providing a first light-sensing means which senses light in a wavelength band of resonance radiation selectively and a second light-sensing means which senses light in two wavelength bands on the longer and shorter wavelength sides than said wavelength band selectively. CONSTITUTION:Light of 4.4mum or around is sensed selectively in a first light- sensing means, while light of 3.0mum and 6.0mum or around are sensed selectively in a second light-sensing means. Concretely, infrared light transmitted through an interference filter 51 of 4.4mum and an interference filter 55 of 3.0mum and 6.0mum is converted photoelectrically by sensors 52 and 56 and amplified by amplifiers 53 and 57 respectively and then inputted to a comparator 54. When the light-sensing intensity by the first light-sensing means is larger than the light-sensing intensity by the second light-sensing means, the light sensed is determined to be of a flame. According to this constitution, it is possible to increase reliability and to reduce the cost.

Abstract: PURPOSE:To measure even particle size distribution of a relatively large particle with high accuracy and high sensitivity, by a method wherein a ring detector is divided into two sections and both sections are combined in a shifted state so that the photodetectors on one side covers the gaps on the other side each other.

This ring tester 5 is divided and the divided sections are shifted so that the gaps G on the other side are overlapped with the photodiodes P each other. By this constitution, the light scattering to each gap part G on the other side is also detected by each photodiode P on one side and the number of measuring points increase. Further, since the gaps capable of removing the effect due to cross talk are provided and it is unnecessary to extremely reduce the width of each photodetector to a degree difficult to mount a lead wire, the number of photodetectors capable of being arranged can be substantially increased.

Filed: 1989-12-27
Abstract: PURPOSE: To transmit as much illumination light as possible without being limited by the size of a light source, by disposing in position two concave mirrors each having a specific shape. CONSTITUTION: Light from a light source 10 is reflected by a first concave mirror 20 and a second concave mirror 30, and transmitted to an input aperture 42 of a non-imaging reflector 40. The light source 10 is disposed near the center of curvature of the first concave mirror 20, and forms a second image 32 at the input aperture 42 by the reflection of both the first concave mirror 20 and the second concave mirror 30. The light source 10 forms a third image 33 near the image 32 by the reflection of the second concave mirror 30 only. Because spherical mirrors with centers of curvature displaced or elliptic mirrors are used as the first and second concave mirrors, most of the light from the light source 10 is efficiently transmitted to the input opening 42. If the first concave mirror 20 adjoins the input aperture 42, the size of the light source 10 is not thereby limited.
