| 摘要 |
An ultrasonic transmitting and receiving transducer reflector assembly (10) including an ultrasonic transducer support (12) and a reflector (14) extending therefrom, the reflector (14) defining a reflective surface (16) having optical power, an ultrasonic transducer (18) producing a beam (22) which is directed onto the reflective surface (16) and providing a signal output from ultrasonic energy reflected thereonto from the reflective surface (16), the transducer (18) being mounted on a mounting surface of the support in off-axis relationship with the reflective surface (16), and a stray energy shield (24) at least partially enveloping the ultrasonic transducer (18) for limiting the angular range of ultrasonic energy which impinges on the ultrasonic transducer (18).
