In a system of analysis of an object or a body by means of "transgraphy" i.e. of radiography by transmission, wherein a receiver transducer and a transmitter transducer are linearly and angularly synchronously displaced, the signal supplied by the receiver transducer modulates one characteristic magnitude--intensity or velocity--of the spot of an electronic tube including a charge storage and memory element, while one line scanned by said spot corresponds to a fixed position of the assembly of t...

A scanning apparatus for scanning which is used in a scanning microscope having an observation apparatus for observing a sample wherein the sample is secured in order to obtain an image of the same. The scanning apparatus includes a moving apparatus for moving at least either the sample or the observation apparatus in order to scan the sample, and a vibration attenuating element structurally provided for the moving apparatus for attenuating relative vibration between the sample and the observati...

A method and apparatus for exposing a pair of radiation sensitive surfaces to a beam of optical radiation is described. The apparatus comprises a support (20) for supporting the radiation sensitive surfaces which may be provided on opposite sides of an identification card. A laser (1) provides a laser beam which impinges on a pair of resonant scanners (10,11) which cause radiation impinging on their respective mirrors to be reflected onto opposite surfaces of the identification card. A control s...

A scanning microscope comprises a sample supporting member on which a sample is supported, a light source which produces a light beam, a light projecting optical device with which an image of the light beam is formed as a small beam spot on the sample, and a light receiving optical device with which the light radiated out of the sample is condensed and an image of the condensed light is formed as a point image. A photodetector detects the point image. A movable member supports at least part of t...

New and improved scanning device and corresponding method that include and involve a movable stage on which a specimen is positioned, irradiation means which irradiates an electron beam onto an irradiation region of the specimen, secondary beam detection means used in generating a picture of the irradiation region by detecting a secondary beam which consists of at least one of secondary electrons or reflected electrons from the irradiation region of the electron beam, an imaging electron optical...

A scanning method for optical scanning of a body includes illuminating the body by a lighting unit and a light receiver unit receives light transmitted from the lighting unit to the body and reflected by the body so that a scanning zone of a scanning unit is defined by the lighting unit and the light receiver unit. Two scanning units each having a scanning region are used, which overlap at least in part in an overlap zone, and at least when the surface of the body is in an overlap zone, the scan...

A method of scanning an information recording medium and a scanning apparatus for an information recording medium that uses the method scan for defects in respective resin layers of an information recording medium that has a plurality of resin layers and a plurality of information layers, which are separated by the respective resin layers, laminated on at least one surface of a substrate. The method includes: an image capture step of emitting scanning light toward the one surface at a predetermi...

A device for the line-by-line scanning of a drawing or pattern, the lines consisting of a plurality of dots, each having at least one of a plurality of different properties, by which signals are produced according to a selected property of the dots by a plurality of checking elements, one for each dot, and visually checking to verify the signals produced before feeding them to a programming memory.

There is disclosed apparatus for scanning a concave coded record which is adapted to be disposed in the inside of an open-ended tube. A rotor carries a source of illumination which illuminates the record. Light reflected from the record is reflected onto a mirror carried by the rotor and passes along the axis of rotation of the rotor through a suitable lens or lenses and is focused on a mask. The mask has an aperture through which light passes to a light receptor such as a photodetector. The lig...

To permit a scanning receiver to automatically or manually scan a plurality of crystals of a local oscillator, a counter receives short-duration timing pulses, with the coincidence of certain of the timing pulses and a signal derived from the squelch circuit in the automatic mode causing the counter to step from position to position, energizing a different crystal at each position, the stepping in the manual mode only occurring when a push-button switch is closed. To conserve power, indicator la...
