ACOUSTIC HEADLIGHT
A method for acoustic imaging includes emitting an acoustic signal. The method includes (a) emitting an acoustic signal; (b) detecting signals corresponding to reflections of the acoustic signal at an array of positions proximate a positon of the emitting; (c) adding, for a chosen distance from the...

| description | A method for acoustic imaging includes emitting an acoustic signal. The method includes (a) emitting an acoustic signal; (b) detecting signals corresponding to reflections of the acoustic signal at an array of positions proximate a positon of the emitting; (c) adding, for a chosen distance from the position of the emitting, a respective time delay to each detected signal to cause each detected signal to correspond to each of a plurality of positions in a plane transverse to a line normal to a plane of the array of positions; (d) summing the time delayed signals; (e) selecting one of the plurality of positions having a highest summed, delayed signal amplitude; and (f) assigning a pixel to the one of the plurality of positions having the highest amplitude. (b) through (f) are repeated for a plurality of different chosen distances. |
