    摘要: A device for modulating the intensity of light rays generated from a gas laser in which an input modulating signal is supplied to a switching element included in a modulating current supply source connected across a gas laser discharge tube to control the discharge current and hence modulate the laser light output. The gas laser discharge tube is eventually subjected to the influence of a magnetic field so as to stabilize the laser light output and modulating characteristic.

    摘要: In order to effect an automatic focus control in an image pick-up apparatus, a photography lens for forming an image of the object onto a two-dimensional solid state image sensing device is arranged in a fixed position, while the two-dimensional solid state image sensing device is arranged movably in the optical axis direction of the photography lens, and the image sensing device is moved in accordance with a focusing error signal detected by a focusing condition detecting circuit having an additional light receiving element mounted on the same substrate as the image sensor but discrete from and operating independently of the image sensor.

    摘要: An information reading apparatus for reading information includes a board having a plane optical waveguide and a light source on the board. Light beam emitted from the source is conducted by a first optical system to a predetermined direction through the waveguide. Part of the light beam is deffracted toward a second optical system by a surface elastic wave region formed in the waveguide. The second optical system conducts the light beam to an information recording region of a card through the waveguide and leads reflected light beam from the information recording region to a photodetector. The light beam not diffracted by the elastic wave region is conducted to a third optical system formed in the waveguide. The system conducts the light beam to a synchronizing signal recording region of the card and leads reflected light beam from the synchronizing signal recording region to a photodetector.

    摘要: An intelligent copier for readily performing image enlargement, reduction, synthesis, and editing. In the intelligent copier, an SIT (Static Induction Transistor) image sensor in which a plurality of SIT image cells are arranged two-dimensionally pixel by pixel in the same substrate is used as an image sensor for picking-up the image of a document. It is not necessary to use an expensive mass storage memory for storing the image information, because the SIT image sensor can perform a nondestructive readout, so that the copier can be made small in size and inexpensive in cost.

    摘要: In a chemical analyzing apparatus of a colorimetric type in which a light flux transmitted through a test liquid is made incident upon a light receiving element through an optical filter having a predetermined transmission spectrum range and a measurement signal is obtained by processing a photoelectrically converted signal, a plurality of optical filters having different transmission spectrum ranges and arranged side by side and a solid state image sensor having a plurality of light receiving elements each having a photoelectric converting element and a static induction transistor are arranged one upon the other. An analytical result is obtained by calculating output signals selectively derived from light receiving elements which are arranged behind a particular optical filter having a transmission spectrum range related to a wavelength determined by a test item to be studied. Since use is made of a static induction transistor, it is not necessary to change the optical filters mechanically and is possible to read out the necessary output signals having high S/N selectively in a prompt manner, while the levels of output signals can be monitored.

    摘要: In a single-lens reflex camera having an objective lens, a focusing screen and a view finder, a photodetector array is arranged to receive a central part of an object image formed by the objective lens and a focusing condition of the objective lens is detected by calculating an evaluation function from image signals supplied from the photodetectors. A presetting dial for selecting given photodetectors whose image signals are used for detecting the focusing condition is provided at such a position that a part of the dial is exposed to the outside through an opening formed in a rear wall of a camera body at a position underneath a film winding lever. A light emitting diode array is provided on the focusing screen so as to be seen by a user through the view finder. Only desired light emitting diodes are lighted on under the control of a signal supplied by the dial to indicate the region of the photodetector array which is used for detecting the focusing condition.

    摘要: A method of detecting a focus condition of an imaging optical system such as a camera, a microscope, a high density optical recording and reproducing apparatus or the like is disclosed. The method comprises a step of selecting, in accordance with the state of density distribution of the optical image, between an image sharpness detection method for detecting in-focused condition by obtaining an evaluation value representing sharpness of images projected upon a photoelectric detecting means and an image lateral shift detection method for detecting in-focused condition by a positional relation between an image projected upon the photoelectric detecting means by light fluxes transmitted through a part of an exit pupil of an optical lens and an image projected upon the photoelectric detecting means by light fluxes transmitted through the other part of the exit pupil of the lens.

    摘要: In a camera, a focus condition of an objective lens system is automatically detected in accordance with a combination of two different type detection methods. A light flux emanating from the objective lens system is divided into two light fluxes by means of a prism having a half mirror and a reflecting mirror and a first light flux transmitted through the half mirror is received by a first light receiving element array via a lenticular lens array and a second light flux reflected by the half mirror and reflecting mirror successively is directly received by a second light receiving element array. The lenticular lens array is so arranged that an exit pupil of the objective lens and the first light receiving element array are conjugated with each other and thus divided images of the exit pupil are projected upon respective elements of each pair of adjacent light receiving elements. At first, illumination signals supplied from the first image receiving element array are processed to derive a first evaluation value on the basis of an image lateral shift detection to indicate roughly a focal condition of the objective lens system. After the objective lens system has driven near the best focus position, illumination signals supplied from the first and second light receiving element arrays are processed to derive a second evaluation value on the basis of an image sharpness detection to indicate finely the focal condition of the objective lens system.
