摘要： In a system for detecting defects on an optical surface, a disk to be inspected is mounted on a turntable, and is attracted on the surface of the turntable. On the disk is provided an optical head having an objective lens located at its focal point on the surface of the disk. A laser beam emitted from a laser unit is projected through the optical head onto the disk, is reflected on the disk, and is then directed through the optical head to a photo detector. The optical head is moved in the radial direction of the disk as the turntable is rotated, and the disk is helically scanned by the laser beam. Only a defect signal is extracted from an electrical signal generated from the photo detector in a defect signal generator. The defect signal is compared in a data processing unit, and is converted to defect information of different size. When it is judged that a prescribed region on the surface of the disk is scanned by a position signal from a position sensor for detecting the position of the optical head, the data processing unit generates an address, and the defect information is stored in each size in specific assigned locations of the RAM. The defect information thus stored is displayed on a CRT or is printed out by a printer.

摘要： A system for focusing an optical head onto a flat surface has a mechanism for moving the optical head in the direction of the optical axis of the head and a mechanism for moving an objective lens in the optical head in the direction of the optical axis of the lens. A laser beam projected from the objective lens of the optical head is reflected on the flat surface, is reflected on the beam splitter, and is introduced into a detector unit. The detector unit thus generates a focusing signal having a level responsive to the distance between the objective lens and the surface. The optical head is lowered by the mechanism for moving the optical head in accordance with the focusing signal when it passes a predetermined point, and is operated to locate the focal point of the objective lens on the surface. Thereafter, the mechanism for moving the optical head becomes inoperative, and the mechanism for moving the objective lens is operated. This mechanism operates in accordance with the focusing signal and locates the focal point of the objective lens always on the surface.

摘要： An apparatus for detecting optically defects in object such as original glass disc for use in manufacturing video and audio discs by projecting a laser light flux onto the object includes an objective lens for focussing the incident laser light flux onto the object as a small light spot, the laser light flux passing through the objective lens at only its central portion. When the object has no defect in the light spot area, the laser light flux is regularly reflected by the object surface, but when the object includes a defect in the light spot area, the light flux is scattered by the defect. The directly reflected and scattered light fluxes are collected by the objective lens and are then separated from each other by means of a small mirror arranged in an optical axis of the directly reflected light flux. The directly reflected and scattered light fluxes thus separated are received by first and second light detectors. A cylindrical lens is inserted between the small mirror and the first light detector having four divided light receiving regions. The objective lens is driven into an in-focussed position under the control of a focussing error signal which is derived by processing output signals from the four divided light receiving regions. A defect signal is derived by processing output signals supplied from the first and second light detectors.

摘要： An input signal containing a base line which fluctuates to a great extent is detected or restored by comparing the input signal with reference levels which are shifted in accordance with the fluctuation of base line. The input signal is sampled at a variable sampling rate and an average of sampled values for a predetermined period is derived to produce a profile signal which resembles accurately the fluctuation of the base line. The profile signal thus obtained is added to upper and lower threshold voltages to produce the reference levels which have been corrected in accordance with the fluctuation of the base line of input signal.

摘要： In order to read out information recorded on a disc rotating at a constant angular velocity by means of a pick-up head movably arranged in a disc radius direction, a head position on the disc is detected to obtain a position signal representing a distance from a disc center to the pick-up head, and then a pulse signal having a frequency corresponding to the position signal thus obtained is generated. A detection signal supplied from the pick-up head and the pulse signal are supplied to an AND gate and pulses of the gated out pulse signal are counted by a counter. The number of the counted pulses represents correctly a length of the information recorded on the disc irrespective of position of the information on the disc.
