The Adafruit TMF8801 Time of Flight Sensor is a great Time of Flight distance sensor from ams Osram in the TMF series of chips. The TMF8801 in particular can do 20mm to 2.5 meters at 33 Hz update rate. The sensor contains a very tiny invisible laser source and a matching sensor. The TMF8801 can detect the 'time of flight', or how long the light has taken to bounce back to the sensor. Since it uses a very narrow light source, it is good for determining distance of only the surface directly in front of it. Unlike sonars that bounce ultrasonic waves, the 'cone' of sensing is very narrow. Unlike IR distance sensors that try to measure the amount of light bounced, the TMF is much more precise and doesn't have linearity problems or 'double imaging' where you can't tell if an object is very far or very close.
