A 250-day experiment using a ring laser achieved unprecedented accuracy in measuring Earth's axial wobble (nutation and precession), surpassing previous gyroscope and ring laser technologies by a ...

Scientists from the University of Rochester and UC Santa Barbara have built a laser so small it can sit on a penny. But don’t let its size fool you. This tiny laser could power the next generation of ...

Able to measure in two axial directions, the Microgage 2D alignment kit from Pinpoint Laser Systems is useful for precision measuring, machine alignment, calibration, and other demanding industrial ...

The novel LIDAR ("light detection and ranging") system could have applications from precision manufacturing lines on Earth to maintaining networks of satellites in perfect formation, creating a giant ...

Space. The final frontier. Unfortunately, the vast majority of us are planet-locked until further notice. If you are dedicated hobbyist astronomer, you probably already have the rough positions of the ...
