Abstract
A miniature rangefinder includes a housing, a micromachined ultrasonic transducer, and signal processing circuitry. The housing includes a substrate and a lid. The housing has one or more apertures and the micromachined ultrasonic transducer is mounted over an aperture. The micromachined ultrasonic transducer may function as both a transmitter and a receiver. An integrated circuit is configured to drive the transducer to transmit an acoustic signal, detect a return signal, and determine a time of flight between emitting the acoustic signal and detecting the return signal.
