Meaghan's Minute: Laser Power

Today on Meaghan's Minute, brought to you by Memory Protection Devices, measuring optical power employed aiming a laser at a coated detector, measuring the detector’s temperature change, and determining the electrical power needed to generate an equivalent amount of heat. An extremely accurate method, but difficult with high-power lasers.

The National Institute of Standards and Technology, or NIST, has demonstrated a new method by reflecting the light off a mirrored scale, which behaves as a force detector.

A little odd, but a promising technique that is more simple, faster, and less costly, as, well as more portable than conventional methods used in manufacturing, the military and research.
