Title: Method and apparatus for detecting pit in sheet-like object
Inventor: FUSE MASAKI
IPC: G01B11/22
Filed: 1995-12-21
Abstract: PROBLEM TO BE SOLVED: To accurately detect only a pit by measuring a length, a width and an area of an image of the pit, expanding the image, recognizing as one pit even when the image suddenly moves in a widthwise direction, and changing failure judgement items in accordance with measuring values. SOLUTION: A sheet-like object 2 to be inspected is transferred on a plurality of rotating rollers 1, with a light cast onto a surface of true object from an illumination device 3. A specular reflection light. is detected by a line sensor 4. An output signal of the sensor is processed at a differentiation circuit 5, A/D converted and binarized at an image-processing circuit 6 to a run length code for the compressing purpose of data. A host computer 7, with expanding the run length code, carries out coupling of a plurality of lines. As a result, a length-width ratio of a region probably including a pit is detected while a transferring direction of the object 2 is set as a longitudinal direction. If the ratio is not larger than a predetermined value, the presence/absence of the pit is judged with the use of an area of the region.  If the ratio exceeds the predetermined value, the presence/absence is judged with the use of the width of the region.

Title: Optical low-pass filter and image pickup device
Inventor: ONISHI IKUO
IPC: G02B27/46
Filed: 1991-12-09
Abstract: PURPOSE:To prevent deterioration of picture quality by suppressing ring-like flares which appear on an optical low pass filter formed with a diffraction grating on the surface of a light transmitting substrate. CONSTITUTION:Thickness (t) of the substrate of the optical low pass filter 2 is determined to satisfy the relation of formula when the grating formed surface 2a of the filter 2 is arranged facing the side of a solid state image pickup element 4. In formula, (n) is the refractive index of the substrate and (x) is the longitudinal length of the pickup surface of the solid state pickup element 4. Thereby, radius of the ring-like flare increases to be larger than the area of the pickup surface, so that no ring-like flare appears on the plane, or even if the ring appears, its intensity is decreased and the ring is less observed.

Title: Optical waveguide device for surface illumination
Inventor: FURUKAWA MASAAKI
IPC: G09F13/00
Filed: 1991-12-09
Abstract: PURPOSE:To uniformalize the brightness of the surface of a liquid crystal display device, etc., and to maintain high brightness as well with the optical waveguide device for illuminating this surface. CONSTITUTION:Plural planar optical waveguide layers 5a, 5b, 5c... successively having refractive indices N1>N2>...>NK>>NL, are laminated on a low- refractive index layer (N1) or high-reflectivity layer 4. The light of a light source 2 is made incident on this device from the light incident end face 7a thereof and a light diffusion layer 3 of refractive indices NH>N1 is brightened by the light emitted from the light exit end face 7b of a flat surface. The light propagating in the underlying long planar optical waveguide layer 5a weakens but the light of the adjacent planar optical waveguide layer 5b is propagated by total reflection between the overlying planar optical waveguide layer 5c and the low-refractive index layer or the high-reflectivity layer 4. This light is made incident on the planar optical waveguide layer 5a and makes interference to compensate the deficiency of the light quantity thereof and, therefore, the brightness of the surface is uniformalized. Since the layers are so constituted as not to generate a light loss in the optical path, the high-brightness illumination is assured.
