Publication number: 20070146689Abstract: In an measuring method for optical transfer function of the invention, irradiating-light from a light source (31) scans an element to be measured within an image sensor of an imaging camera constituted by integrating an imaging optical system and the image sensor. The element to be measured converts sequentially the irradiating-light into an electrical signal and outputs the electrical signal. Further, based on the outputted electrical signal, point spread function data is generated, and subjected to Fourier transform to calculate an optical transfer function. Accordingly, a method is provided for measuring an optical transfer function for properly restoring image degradation due to factors including the position of the imaging optical system within the imaging camera and inter-element cross talk.Type: ApplicationFiled: January 13, 2005Publication date: June 28, 2007Applicant: MATSUSHITA ELECTRIC INDUSTRIAL CO., LTD.Inventors: Nobuhiro Araki, Katsunori Waragai

Patent number: 6597451Abstract: In a spectrographic type spectrometry measuring apparatus employing a concave holographic diffraction grating or a replica thereof, a small-size and light-weight spectrometry measuring apparatus having a high reliability with a spectrum position does not move in a photo detector plane in spite of an occurrence of a temperature change. This measuring apparatus is composed of a light-condensing device, a concave holographic diffraction grating or a replica thereof, and a telecentric correction lens for condensing a diffracted light from the diffraction grating telecentrically on the spectrum condensing plane. In this constitution, the spectral ray enters vertically to the spectrum focusing plane, and if the photo detector is moved in the optical axis direction due to a temperature change, the spectrum is not moved on the photo detector surface, and it is not necessary to calibrate an optical element due to an ambient temperature change.Type: GrantFiled: October 12, 2000Date of Patent: July 22, 2003Assignee: Matsushita Electric Industrial Co., Ltd.Inventor: Nobuhiro Araki

Patent number: 4771157Abstract: An electrical discharge machining apparatus for forming minute holes in a workpiece has a machining electrode supported in V-shaped grooves for forming a minute hole through an electrical discharge between the machining electrode and the workpiece. The machining electrode is movable toward and away from the workpiece. The workpiece is movable between a position below the machining electrode and a position below a microscope disposed in conjugate relation to the machining electrode. After a position to be machined has been set by the positioning means, the workpiece is moved to the position below the machining electrode for electrical discharge machining. The machining electrode is subjected to little displacement while it is being rotated, and the position to be machined can be determined with high accuracy.
