Determination of the distance to a soft sound object, whereby measurements are made at two or more different frequencies so that a material dependent phase correction can be made
Determination of the distance to a soft sound object, whereby measurements are made at two or more different frequencies so that a material dependent phase correction can be made
Method for distance measurement using ultrasound, whereby sound is reflected from or transmitted through soft sound objects. To determine a material dependent phase correction angle the ultrasound measurements are made at two or more different frequencies.
