Claims
- 1. An acoustic pulse generator comprising an acoustically transparent housing, an aprotic liquid contained within said housing, means for effecting heat exchange with said liquid, at least two spaced electrodes contained within said liquid and each of said electrodes extending from said housing, a matching medium coupled to said housing, means for generating a spark across the spaced electrodes to produce a pressure pulse in the aprotic liquid and means for transmitting the pulse from the liquid to the matching medium.
- 2. An acoustic pulse generator as defined in claim 1 wherein the spark generating means comprises a variable voltage source capable of producing a field exceeding the breakdown field.
- 3. An acoustic pulse generator as defined in claim 1 wherein at least one wall of the housing is a flexible membrane adapted to transmit the generated pressure pulse from the aprotic liquid to the matching medium.
- 4. An acoustic pulse generator as defined in claim 1 wherein at least a portion of the housing is optically transparent and the spark generating means comprises a voltage source for establishing a field having a magnitude below the breakdown field magnitude and means for applying a controlled light pulse to the optically transparent portion of the housing.
