Inside the Head of a Systems Integrator
Somewhere, someday, someone may employ photonics to build a better mousetrap. The invention will require some sort of sensing component -- an interferometer, perhaps, or an infrared camera equipped with illumination, an image processor and pattern-recognition software to route signals via computer to a galvo-mounted laser. The laser component will require some sort of power supply, resonator or...
