    摘要: In a preferred embodiment, a two-electrode discharge device, or ''''optical multipactor,'''' for modulation of high-power radiation beams, especially adapted for switching or attenuating laser beams; the device providing an inter-electrode gap with electron cloud oscillating thereacross, operating as secondary electron emission in resonance mode with the passing beam. This device is capable of providing much faster beam switching, wider modulation bandwidths and extremely low capacitance, such that its power requirements (for such modulation and switching of high-power beams) are greatly reduced, as is the likelihood of damage from the beam.

    摘要: An apparatus and method for the visual observation of a latent magnetic image recorded on a magnetic member. The apparatus comprises: a nonmagnetic vessel, positioned above the magnetic member, having a broad shallow cavity containing magnetically active particles in a fluid or a vacuum; and a magnet to produce an external magnetic field. The magnetically active particles collect on the latent magnetic image to produce a visual image. If the external magnetic field is constant, the resolution of the visual image is increased. If the magnetic field is cycled between alternating polarity and is of sufficient intensity, the image reverses and the speed with which the visual image can follow changes in the latent magnetic image is increased.

    摘要: An optical shutter in the form of an electrochemical cell responds to an intense light flash to switch from a light transmitting condition to a light scattering condition. The cell includes a pair of electrodes separated by an electrolyte, and normally provides an optical path therethrough. A fast response photoelectric detector is positioned adjacent the cell to sense any intense flash of light falling on the cell, and thereupon to trigger a capacitive discharge through the electrodes and electrolyte of the cell via a high speed switching circuit. The electrolyte decomposes in response to the passage of electric current therethrough to evolve large quantities of gaseous products which form a film of fine bubbles at the electrodes. The bubbles constitute an irregular reflecting surface effective to scatter incident light. Transparency is resumed upon clearing of the bubbles, which may be accomplished by applying supersonic vibrations to the solution, or by elapse of time.
