IPC: G01J9/04
Filed: 1979-05-10
Abstract: PURPOSE:To obtain local oscillation light and make possible always stable light heterodyne detection by branching part of the emitted light of a laser for light source and applying a suitable frequency shift to this in a laser radar. CONSTITUTION:Infrared light from a CO2 laser 15 is led to a switch 6 via splitter 5 to make CW light to pulse light which is then subjected to TEA amplification 7 and is thence radiated to the observation target. On the other hand, the branched continuous wave is led to an acousto-optic A/O modulator 9a by a mirror 8 and the light emitted by an angle of theta by the excitation of an oscillator 10 is entered to an A/O modulator 9b, by which it again receives the shift of an angle theta and is thence emitted. The shift amount of this angle 2theta results in that the conditions as the local oscillation wave of a heterodyne detector of, e.g., 100MHz in intermediate frequency are provided. This shifted light is entered together with the incident light to a detecting element 2 by way of a mirror 11 and splitter 1.

Abstract: PURPOSE:To radically curtail the delay in starting discharge, to downsize, and to have high protective ability by arranging an electrode for discharge through a dielectric so as to form a creeping discharge path and an arc discharge gap. CONSTITUTION:A dielectric 4 is put between a pair of electrodes 2, 3, at least one of which forms a creeping discharge electrode on the dielectric surface, as well as an arc discharge electrode between both of the electrodes. When a lightning surge, etc., is applied, large electrostatic field distortion is generated at a boundary of a back electrode formed by one of the electrodes arranged through the dielectric 4; at first, creeping discharge is generated along the dielectric surface at a creeping discharge path 4a of the first electrode 2 and an edge of the second electrode 3, and is moved to an arc discharge of gaps 2b, 3b between the first electrode 2 and the second electrode 3. When it becomes an arc discharge or main discharge, voltage during discharge is reduced, and the creeping discharge is stopped. The creeping discharge plays a part of a high-energy trigger in a short period of time without discharge delay.
