Meskernel has introduced a high-accuracy Laser Distance Sensor offering 1mm precision over a 200-meter measurement range.

Laser-plasma accelerators can accelerate particles over distances that are up to 1,000 times shorter than those required by ...

This Arduino code utilizes an ultrasonic sensor to measure distances. When an object is detected within a fix distance , the connected motors trigger a sequence: move backward, turn right, turn left, ...

sensor, which uses the out-and-return time of a laser beam to measure distance—not detect motion—with accuracy of less than a centimeter. Light did not have the delay problems of sound.

Laser optical displacement sensors measure from a relatively large distance from the object and with a very small light spot, which allows measurements of extremely small parts. The distance from the ...

This concept involves a beam produced by a laser diode reflecting off the measurement object and being directed onto the sensor’s receiving element by optics. The position of the reflected light ...

This project provides ROS drivers for Bosch Off-Highway sensor systems. (Radar Off-Highway Premium, Radar OHW, General Purpose Radar Off-Highway (GPR), Ultrasonic Sensor System OHW Entry & Premium) ...

The UK government has awarded a £180K grant to Sentinel Photonics to develop a sensor to detect and identify laser threats in civilian contexts. The original technology was created by the Dstl ...

An Arduino Uno and the relays for the laser and fans sit on the MicroSlice’s bottom platform, and two EasyDriver motor controllers sit above them on the next layer. Swing by the Instructables ...

[over9k] used his Arduino to set up a laser trip wire. The laser is mounted along side the Arduino, reflects off of a mirror, and shines on a photoresistor that interfaces via a voltage divider.
