Ultrasonics
Ultrasonics work on the principle of transmitting sonic pulses which are echoed back should a target be introduced into its' path. The integrated controller of the ultrasonic computes the distance from the echo time and the velocity of sound. The transmitted and returned signal requires a certain distance before the sensor starts to detect its target. This is called the blind region.
Ultrasonics are available in various scanning ranges and outputs:
