  • 1. What is Stray Light - Photon Engineering

    Light-detector meaning A device used in an optical transmission system to detect an optical signal generated by a light source and propagating through a medium. A light detector essentially is an optical receiver that is paired with an optical transmitter, both of which are connected to electrically based devices or systems.

  • Smoke detectors explained - IFSEC Global

    2021-4-13 · A photoelectric detector senses sudden scattering of light when smoke enters the detector chamber, triggering the alarm. Photoelectric smoke detectors respond an average of 15 to 50 minutes faster to fire in its early, smouldering stage, before it breaks into flame, than ionisation alarms. They can be installed near kitchens.

  • High Reflectivity Mirrors | Edmund Optics

    The reflected laser light oscillates in the resonant cavity and a small amount of light is lost with each reflection. A detector placed after the second mirror measures the decreasing intensity of the reflected light. The total loss of the mirrors is determined by the decay time, or “ring down”, of the reflected light.

A laser beam driving the cavity at its resonance frequency will acquire red- and blue-shifted sidebands due to noise in the position of the mechanical oscillator. In a classical theory without noise in the electromagnetic field, the powers of these sidebands are of equal magnitude.
