ABSTRACT:
An ultrasonic detector of the present invention includes an ultrasonic transducer for detecting ultrasonic energy and generating an electrical signal having an amplitude corresponding to the detected level of the received ultrasonic energy, and a light source supported in proximity to the ultrasonic transducer for illuminating an area from which the ultrasonic transducer may detect ultrasonic energy. Preferably, the light source is a directional light source positioned such that an optical axis of a light beam emitted from the light source intersects a directional axis of the ultrasonic transducer at a predetermined distance from the ultrasonic transducer. The ultrasonic detector of the present invention also preferably includes an indicator light coupled to the ultrasonic transducer for receiving the electrical signal output from the transducer and for indicating the relative amplitude of ultrasonic energy received by the transducer.
