摘要： A camera system includes a single pixel photo-sensor disposed in or on a substrate to acquire image data. A micro-lens is adjustably positioned above the single pixel photo-sensor to focus external scene light onto the single pixel photo-sensor. An actuator is coupled to the micro-lens to adjust a position of the micro-lens relative to the single pixel photo-sensor. A controller controls the actuator to sequentially reposition the micro-lens to focus the external scene light incident from different angles onto the single pixel photo-sensor. Readout circuitry is coupled to sequentially readout the image data associated with each of the different angles from the single pixel photo-sensor.

摘要： Laser active imaging system allowing in particular to use a wide field by means of a detecting device including a linear array of N juxtaposed photodetector elements oriented along the direction of scanning and associated with a focusing lens. The receiver includes a circuitry receiving the N detected channels and is equipped with compensation circuits for the time shift exhibited by the video signals as a function of the distance so as to bring the illuminated objects back to their angular location for the display of the observed field. The processing circuits include circuits for measuring the amplitude and the Doppler shift and for identification of the distance through the rank of the detection channel.

摘要： A system for converting infrared radiation in the 8-14 micron region to a real time visual image is disclosed. A lens system focuses the image at an image plane. A plurality of mirrors are disposed between the lens system and the image plane and are rotated about an axis intersecting the optical axis at the entrance pupil. Each mirror is disposed to focus an arcuate segment of the image onto a linear array of detectors located substantially on the axis of rotation as the mirror moves through the optical field of view. The image thus scanned is reconstituted at the target of a vidicon type television camera by the same type of system having mirrors rotated in synchronism with the scanning mirrors, but utilizing light emitters rather than light detectors. The video signal from the television camera is then displayed on a conventional television display tube for visual observation.

摘要： Real-time focusing in a slide-scanning system. In an embodiment, focus points are added to an initialized focus map while acquiring a plurality of image stripes of a sample on a glass slide. For each image stripe, a plurality of frames, collectively representing the image stripe, may be acquired using both an imaging line-scan camera and a tilted focusing line-scan camera. Focus points, representing positions of best focus for trusted frames, are added to the focus map. Outlying focus points are removed from the focus map. In some cases, one or more image stripes may be reacquired. Finally, the image stripes are assembled into a composite image of the sample.

摘要： Briefly, in accordance with one or more embodiments, a closed loop feedback system for electronic beam alignment in a scanned beam display comprises a light source to emit one or more light beams, a controller to provide a control signal to drive the light source, a scanning platform to receive the one or more light beams and scan the light beams in a scanning pattern to project an image, and an alignment detector to provide a feedback signal indicative of beam position information of the light beams in the far field to the controller. An optic may be disposed in the beam path to magnify and/or to transform beam position information into the far field for the one or more alignment detectors. The controller adjusts the control signal in response to the feedback signal received from the alignment detector to maintain alignment of the light beams in a far field.

摘要： The optoelectronic rotary scanning device comprises optical receiving means, optical elements driven together in rotation by an afocal system consisting of at least two cylindrical optical elements designed to rotate about an axis perpendicular to the plane of their generator-lines, and an optical element for focusing on an array of detectors extending radially from the perpendicular axis. Videofrequency means are provided for processing the signals delivered by the detectors, the signals being multiplexed and stored sequentially in memory after transcription to cartesian coordinates. The videofrequency processing means also comprise a loop which subtracts the integrated mean value of the signals of all the detectors from each signal of each detector and a circuit for correcting thermal-drift residual voltages of the amplifying circuits of the detectors.

摘要： A display system includes a beam of light that is repetitively deflected through a scanning pattern so as to define one line of an image raster. The beam deflection is a result of diffractive interaction of the beam with a train of acoustic waves that change in frequency repetitively through a range of frequencies and which are developed by a source of signals that correspondingly changes frequency repetitively. A transducer responds to those signals to develop the acoustic waves and has an input at which a capacitive reactance is presented; the effect of that reactance is to diminish the response of the transducer to the applied signals. In order at least partially to compensate that capacitive reactance, a matching network is coupled between the source and the input and includes an element which has an adjustable reactance. This element may be a saturable reactor or the like controlled so that its reactance is varied automatically to its compensatory value at each frequency as the signals change in frequency throughout their range.
