Abstract
A new ultrasonic transmission imaging apparatus is disclosed, which uses a new imaging method providing image focusing capability. The apparatus comprises an ultrasonic emitter producing substantially continuous coherent ultrasonic waves toward an object to be inspected. The apparatus further comprises an ultrasonic detectors array comprising a plurality of ultrasonic detectors receiving the object traversing ultrasonic waves to produce a plurality of series of electrical signals coming from the ultrasonic detectors, the electrical signals characterizing transmission of the ultrasonic waves through the object and being associated with series of image elements. The apparatus further comprises a signal vector components detector detecting signal vector components for each of the electrical signals. The apparatus further comprises a computer for controlling the apparatus and for receiving pairs of first and second signal vector component digital signals coming from the signal vector components detector. The computer has a memory for storing the pairs of first and second signal vector component digital signals and for storing focusing function data, which is used by the computer to pro…
