  • Passive (cooperative) hologram radar
    Real-time read-out can also be achieved by successivelysampling the array elements and introducing their outputs into an ultrasonic cell which, by virtue of the Debye - Sears effect, can modulate (diffract) a co- herent light beam in almost the same way...
  • Time-optimal control of sampled-data systems
    Real-time read-out can also be achieved by successivelysampling the array elements and introducing their outputs into an ultrasonic cell which, by virtue of the Debye - Sears effect, can modulate (diffract) a co- herent light beam in almost the same way...
  • Handbook of Optics: Volume I - Geometrical and Physical Optics, Polarized Light, Components and Instruments, Third Edition > OPTICAL SPECTROMETERS
    The ultrasonic Debye - Sears modulator overcomes the experimental difficulties associated with both Pockel cells and Kerr cells.

    A particularly easy ultrasonic absorption experiment to understand and perform is the laser Debye - Sears technique. ...a quartz piezoelectric transducer into a 30-ml (1.83-in.3) sample cell that has entrance...
  • http://advlabs.aapt.org/advlabs/bfy/files/UltrasonicsConceptualIntroductiontotheExperiment.pdf
    The electronics box includes a built-in power supply for operating the solid-state laser needed to observe the Debye - Sears effect. A special broadband ultrasonic transducer is mounted on top of a water-filled cell .
  • A method for comparing ultrasonic velocities in solids and liquids using a spectrometer
    It is known that unlike the conditions which apply in an ordinary light grating, the diffraction pattern produced by a Debye - Sears ’ optical cell is clear and visible only when the light wave front is normal to the sound beam. This fact can be taken advantage of for the accurate determination of ultrasonic velocities. . v/ . liquids. . workshop...
  • A modified flap-type vacuum valve
    It is known that unlike the conditions which apply in an ordinary light grating, the diffraction pattern produced by a Debye - Sears ’ optical cell is clear and visible only when the light wave front is normal to the sound beam. This fact can be taken advantage of for the accurate determination of ultrasonic velocities. . v/ . liquids. . workshop...
