Abstract: A method and apparatus for determining a thickness of an object using ultrasonic signals are disclosed. The method includes the steps of transmitting ultrasonic signals toward the object, digitizing a reflected echo sequence of the ultrasonic signals, including interpolating the echo sequence, and processing the echo sequence by detecting maximum amplitude peaks in the echo sequence and determining the object thickness based on a time duration between the maximum amplitude peaks.
