摘要： In a CCD solid state image sensing device in which a photosensitive section is constructed by a photodiode formed by a PN junction between a first P-type well region and an N-type impurity diffusion region formed on an N-type silicon substrate, the N-type impurity diffusion region is formed by the ion implantation of single substance of arsenic (As). According to this CCD solid state image sensing device, a bright flaw on an image sensing screen, which is one of the defects encountered with an image sensing screen, can be reduced. Also, the n-type impurity diffusion region constructing the PN junction can be reduced in size and the CCD solid state image sensing device itself can be made compact in size. Further, a method of manufacturing a CCD solid state image sensing device also is provided.

摘要： A range finder includes an improved module structure, that facilitates injecting a transparent filler uniformly into the entire light guide spaces neither leaving any unfilled region nor impairing the characteristics thereof. A channel of flow (or U-groove) is formed across a partition wall, connecting light guide spaces arranged side by side. This feature allows smooth flow of transparent filler into the range finder module without an unfilled region and consequently no overflow of the transparent filler onto outer wall of the plastic module and onto terminal portion of the lead frame. Another feature of this invention is the presence of shield walls along the channel of flow protruding from the side walls of the channel of flow in an inter-digitated fashion, to prevent the stray light from one light guide space entering the other light guide space through the channel of flow.

摘要： The range finder measures the distance to the object based on the principle of triangulation, and includes a pair of lenses; a lens supporting frame; a CCD supporting plate; CCD packages supported by the plate; and temperature sensors. One sensor is positioned on the frame between the lenses, and the other is positioned on the plate between the CCD packages. Each CCD package includes a CCD chip located at a focal plane of the lens, a casing and a transparent plate. The lenses, frame, casing and transparent plates are made of the same plastic material so that the thermal expansion of the entire range finder caused by the temperature change may not affect to the distance measurement. Bonding ribs connected to the transparent plate are located near an image ray hole to face each other and on the line perpendicular to the optical axis of the CCD chip and the plane containing the optical axes of the CCD chips. Therefore, the thermal deformation of the transparent plate in the base line direction of the range finder may not affect significantly. The range finder of the invention can reduce the distance measurement error caused by nonuniform thermal deformations of the parts.

摘要： A distance-measuring apparatus is formed of a photographic device formed of a pair of image-forming lenses and photosensor arrays for taking images of an object through the image-forming lenses, and a calculating device electrically connected to the photosensor arrays for calculating a distance to an object to be measured by two images of the object taken by the photographic device based on a triangulation principle. The calculating device calculates the distance to the object by an amount of shift determined based on an inter-optical-axis distance of the pair of image-forming lenses and photographed images of a reference object having a pattern of a periodic structure repeated at an interval same as the inter-optical-axis distance; a difference in offsets of image-forming positions on the photosensor arrays caused by a medium located between the apparatus and the measured object, with the difference being detected based on the amount of the shift; and an amount of shift detected when the distance to the measured object is measured.

摘要： A method of the invention corrects a detection error, caused by an assembly error, in a distance or a distance-related index detected from an image captured in the visual field of an image detection module including an optical device and a pair of image sensing devices, each including a plurality of image sensors. In the method, the visual field is divided into windows disposed in a two-dimensional matrix format in order to detect the distance or a parallax for a pair of images in each window; the characteristics of an error is expressed in a detected value caused by an angle error in the assembly of the image detection module, as a quadratic polynomial for two angle variables indicating the position of the window within the visual field; parallax for a plurality of windows is detected after a test sample image has been provided to the module; the coefficient value for each term in the polynomial is determined based on the results of the detection, and these values are stored in a storage device; and, when using the image detection module to detect actual distances, the detected value for each window is corrected by adding to it the value of the polynomial to which the stored values of the coefficients and the values of the variables indicating the position of the window are applied.

摘要： Apparatus and a method for producing Fourier spectra for a test object utilizing a plurality of laser interference signals each having a period corresponding to a wavelength of a laser beam and being out of phase by 1/n of the wavelength of the laser beam, n being a positive integer above 1. An infrared interference signal representing the test object after the test object is irradiated with an infrared light beam is sampled at a time interval corresponding to 1/n of the wavelength of the at least one laser interference signal and n sets of sampled data corresponding to the infrared interference signal are produced. Each set of sampled data is Fourier-transformed independently from the other to generate a Fourier spectrum corresponding to each set. All of the independently generated Fourier spectra are later combined to produce a Fourier spectrum corresponding to the infrared interference signal.
