Abstract
A scan acoustical holographic imaging apparatus is disclosed that is capable of displaying an isometric image of an object scanned with acoustical energy in which the image visually depicts surface contour information. The apparatus includes mechanisms for generating X, Y and Z electrical distance signals as an acoustical transducer is scanned in a scan plane over the object. The apparatus further includes mechanisms for generating object signals that are mixed with a holographic reference signal that may be phase shifted to produce a resultant holographic object signal which is used to modulate the brightness input of a CRT display device. The X, Y and Z electrical distance signals are transformed into an electronic isometric projection and applied to the horizontal and vertical inputs of the CRT display.
