Abstract

1446022 Ultrasonic imaging system HOLOTRON CORP 18 March 1973 9102/73 Heading H4D An ultrasonic scanning system for investigating an object includes an ultrasonic source, a point-like receiver, and an acoustic lens for directing ultrasonic waves from the object on to the receiver. The source and/or receiver is scanned in a curved path about an axis of rotation and either the axis is moved relative to the object or the radial distance of the source or receiver from the axis is changed. In the Fig. 1 holographic system reflected ultrasonic waves from an object 11 in a liquid container 19 are detected by a receiver transducer 17 on a rotating disc 21 moved at right angles to the axis of rotation. The transducer output is mixed at 23 with an electrical coherent reference signal and the resulting hologram signal modulates the brightness of either a CRT beam or a lamp 31. The CRT beam or lamp is scanned in synchronism with transducer 17 and is photographed to give a hologram which can be reconstructed by convergent laser light (Fig. 7, not shown). The rotating disc may carry one or more (in the latter case sequentially-used) transmitting and/or receiving receiving transducers instead of the single transducer shown, and may be moved parallel to (instead of at right angles to) the axis of rotation (Figs. 2 to 6, not shown). Alternatively the transducers may be mounted along a radius of the disc, on a slide which is moved radially by a cam at a selectable rate, to give a spiral scan providing selectable resolution (Fig. 9, not shown). In the Fig. 10 embodiment, for direct imaging underwater, ultrasonic energy from transmitters 193, 195 is reflected by an object field on to an acoustic lens 197 and hence directed to a scanning plane in which are arranged radially-aligned and movable receivers 185 on a rotating disc 181. The receiver outputs are displayed on a synchronously scanned CRT 191. The lens comprises a liquid-filled chamber with two flexible films as its boundary, and its focus is variable by moving the fluid to or from a supply 199. Housing 189 contains a coupling fluid. Alternatively the lens may comprise a chamber with one flexible film as its boundary, the disc 181, receivers 185 and coupling fluid being arranged within the chamber (Fig. 13, not shown). The invention is applicable also to systems in which ultrasonic energy is transmitted through, rather than reflected from, an object to be imaged.
