An ultrasound sensor for exploring an area of space and/or for contactless distance measurement has at least one ultrasound transducer (12) for sending ultrasound pulses and/or receiving the ultrasound pulse echo and a device for focusing the ultrasound pulse energy in the area of space to be explored or the ultrasound pulse echo energy on the ultrasound transducer(s). The ultrasound pulse energy focusing device has a reflector with a reflecting surface (2) made of nth order, preferably 2nd order, paraboloidal surfaces. |
