  • Patent number: 4705401
    Abstract: The invention is a method and apparatus for automatic mensuration of three-dimensional surfaces. The surface is sensed via non-contact optical triangulation means and the optically produced image measured by electronic means. The electronic measurements are encoded as binary data and passed to a digital computer for storage, analysis and other functions. The invention is significant because of the speed and relative simplicity of the method and a provision for alleviating shadowing from large surface irregularities. The apparatus has no moving parts, excepting a mechanism to provide for movement of the apparatus relative to the surface so as to progressively view the entire surface. This invention projects two or more planes of light which intersect the surface at known angles, producing illuminated lines. Said lines are viewed by a video type camera placed at a known angle away from the planes so that displacements in the line may be sensed.

  • Patent number: 4451923
    Abstract: Herein is disclosed a method of and apparatus for measuring optical frequency variations wherein linearly-polarized incident light generated by a tunable laser or the like is delivered to a passive resonant cavity incorporating a linear polarizer such as a Brewster plate so that the reflected light acquires a frequency-dependent elliptical polarization which can be detected by a simple polarization analyzer providing a signal correlated with the frequency variation of the laser. Such signal can be utilized as a feedback error signal to stabilize the laser frequency, or to adjust the cavity resonance. If the cavity is tunable, tuning thereof will in turn provide a precision method for tuning of the laser itself.

  • Patent number: 4325257
    Abstract: The invention involves a digital synthetic-focus, acoustic imaging system which is operative in real time and includes one or more electro-acoustic transducers arranged to receive broadband pulses from a pulse generator for excitation of acoustic pulses which are directed into the region under observation. Signals reflected from an object or discontinuity in the region are received by the same transducers, and after inverse filtering and nonlinear amplification are converted to digital signals. These digital signals are stored in separate high speed random access memory units for storage, but are subsequently time-equalized through use of a programmed focus memory unit prior to delivery to a digital adder and thence through a digital-to-analog converter for ultimate intensity modulation on a raster scanned display unit which provides the real time image.
