摘要： The present invention relates to a device for measuring the reflection of a plane, specularly reflecting surface, in which a measuring beam of radiation is directed onto the surface to be measured through an optical converging lens and the radiation reflected from the surface is directed through the same lens to a radiation receiver. In such a system, preferably, the optical connections between the source of radiation and the converging lens and between the lens and the radiation receiver are established by means of a fiber-optical photoconductor or a lens and mirror systems. Such a device may be employed, for example, for measuring the reflection of thin layers deposited in a vacuum evaporator.

摘要： A method and apparatus for sampling and optically measuring a selected characteristic of flowing granular material in which an optical window located at one end of a hollow sight tube is disposed in the material stream at an angle with respect thereto. A dam is carried by the sight tube downstream of the window to retard material flow and cause material to collect on the window surface. The selected material characteristic may then be measured as a function of an optical characteristic of the material as viewed through the sight tube and window. An air nozzle is disposed adjacent the window to remove the collected material sample at the end of a measurement sequence.

摘要： The specification discloses an optical web inspection system for detecting imperfections in a web having a longitudinal axis and moving in a plane across an inspection area. Radiation means is disposed above the plane of the web and transverse to the longitudinal axis of the web for directing radiant energy on the web at the inspection area. A plurality of sensors are mounted transverse to the longitudinal axis of the web and above the inspection area for receiving reflected radiation from successive transverse portions of the web passing across the inspection area. The plurality of sensors generate electrical output signals representing the intensity of the reflected radiation from the successive transverse portions of the web. Circuitry for periodically summing the electrical output signals from selected ones of the sensors is provided to generate a summation signal representative of the sum of reflected radiation from selected discrete segments of a plurality of the transverse portions of the web. The system further includes circuitry for comparing at least one of the electrical output signals with the summation signal for determining whether an imperfection exists within the web.

摘要： A measuring system for a ring laser mirror, or the like, is provided, whereby the mirror can be quickly scanned and the backscatter levels measured and presented in the form of a map which directly indicates the spots of the mirror where acceptable backscatter levels exist. When such a spot has been identified, the system of the invention is also capable of measuring the reflectivity of the spot, which normally must be approximately 99.7% to be acceptable. The system of the invention has the capability of measuring the reflectivity of the mirror in addition to measuring the backscatter in a single set-up, and without having to manipulate the mirror.

摘要： An elongated cylinder having a hollow interior is provided with a first open end and a second closed end. Reflecting media are provided on the interior portion of the closed end and on half of the inner surface of the circumferential wall surface of the cylinder. First and second scales are provided on the other half of the wall surface, each being translucent in part so that incident light directed into the interior of the elongated cylinder will pass therethrough. The gloss of a surface may be measured by placing the closed end of the elongated cylinder on the surface and directing an incident light into the hollow interior via the first open end, and noting the reflection of the scales in the surface being measured. The glossier the surface, the more of the scales that will be reflected.

摘要： A digital reflection densitometer system comprises a power supply unit and a digital reflection densitometer instrument which is connected to the power supply unit by means of an electrical cable. The instrument is manually positionable over a surface and includes a housing which is supported on a foot. The foot is adapted for engagement with the surface and includes target apparatus for designating a predetermined area of the surface. The housing is normally pivotally separated from the foot by a spring and is manually pivotable to an operating position adjacent the foot.A plurality of lamps are mounted in the housing for illuminating the predetermined area of the surface when the housing is in the operating position. Light reflected from the predetermined area is directed through an optical system to a light sensitive apparatus comprising a planar silicon sensor. The output of the planar silicon sensor is directed through an operational amplifier and a logarithmic amplifier to a digital volt meter which actuates a digital display device mounted in the housing of the instrument to provide a visual digital readout indicative of the output of the planar silicon sensor. The instrument further includes apparatus for selectively positioning any one of a plurality of filters in the path of light passing through the optical system to the planar silicon sensor, and for simultaneously adjusting the gain of the operational amplifier and the sensitivity of the digital volt meter to compensate for differences between the filters.

摘要： The amount of water present on a lithographic printing plate during printing is determined by measuring the amount of water present on a surface which is other than that of the printing plate but which carries an amount of water related to the amount of water present on the printing plate. The surface upon which the measurement is made may be the surface of a control pad mounted on the printing roller in the gap between opposite ends of the printing plate, the surface of one of the rollers of the damp train applying water to the printing plate, or the surface of an auxiliary roller contacting one of the rollers of the damp train applying water to the printing plate. The amount of water subsequently applied to the printing plate may be regulated in dependence upon the amount of water determined as being already present on the printing plate.
