A new device called a gravity-enforced photon momentum radiometer has been developed by NIST. It consists of several key components:
1. A magnetic array that supports a diamagnetic shuttle, which levitates above the array
2. A mirror attached to the shuttle that receives laser light and moves the shuttle based on the optical force
3. A tiltable platform for the magnetic array to allow precise adjustments
4. A photogate that produces gate light blocked by a photo interrupter, providing a detector signal for the shuttle’s position relative to the platform
This device is designed to measure the optical power of laser light with high precision. The ability to track the shuttle’s position accurately indicates its potential importance in quantum standards and related technical updates.
