Many (about 10 or more) years ago I have found an interesting project: a distance measurement system with a webcam and a laser pointer. It's probably long gone, but after these years, I have decided ...

Default value for maximum measurement distance is 4m, since HC-SR04 sensor can't measure reliably beyond that. However, if you are using another sensor or if you you don't care about distances larger ...

Abstract: The hand-held laser distance meter is a small, light, non-contact instrument, widely used in various measurement fields. It is based on the laser ranging theory. This paper would introduce ...

If you’ve been holding out on adding a distance-measuring device to your gear arsenal, now is the time to act, because FlightScope’s i4 Rangefinder is packed with game-enhancing features to help you ...

For decades, physicists have talked about quantum distance, a way of measuring how similar or different two quantum states are. In this strange scale, a distance of one means two quantum states are ...
