What is ultrasonic transceiver?

In general a transciever is a device that is both a TRANSmitter and a reCEIVER. In practice an ultrasonic transceiver sends out sound waves at a frequency well above 20,000 cycles per second, and over a short distance will sense the reflections of these waves. Electronics attached to the receiver portion of the device are able to calculate the distance to the reflecting object. This device was used in the Polaroid SX70 made in the 1970s as part of the automatic focussing mechanism of the camera.
