Abstract: Apparatus and process of laser assisted drilling includes structure and method for receiving laser energy and projecting it onto an object to produce structural changes within the object. Structure and method are also provided for mechanically abrading the structurally perturbed portions of the object. By combining laser and mechanical energy, drilling is quickly and accurately performed.

Abstract: A radar tomography method and apparatus usable in industrial applications emits a plurality of radar pulses toward an adjacent object. A transmitter provides the plurality of radar pulses to the antenna, and a receiver receives the plurality of reflected radar pulses which correspond to the emitted plurality of radar pulses reflected from internal structure within the object. Timer/gate means selects predetermined radar pulses from among the received radar pulses, the selected radar pulses corresponding to a predetermined area of interest within the object. The selected radar pulses include pulses which represent internal structure of interest and pulses which represent internal structure which is contiguous to the internal structure of interest. The selected pulses include information which discriminates the internal structure of interest from the contiguous internal structure.

Abstract: A radar tomography method and apparatus generates a plurality of radar pulses in a transmitter and projects them with an antenna toward a patient. Radar pulses reflected from the patient are picked up by the antenna and conducted to a receiver. Predetermined radar pulses are selected from among the received pulses by a timer/gate circuit connected to the receiver. The selected radar pulses correspond to a predetermined area of interest within the patient. A representation of the predetermined area within the patient may be displayed with known display apparatus. The antenna may also be moved relative to the patient, in order to produce three-dimensional information. Synchronizing the transmitter, the time/gate device, and the movement of the antenna may be effected with a synch processor, and a matrix filter may be used to focus the emitted radar pulses and to reduce noise in the return radar pulses.
