Abstract
A laser safety device and method of protecting against harmful levels of radiation. The device includes a housing with first and second apertures. A photodetector generates a first signal corresponding to a level of radiation entering the housing through the first aperture. A control circuit receives the first signal and generates a drive signal based upon the level of the radiation. A reflector array which can include micro-electro-mechanical mirrors receives the drive signal and diverts a first part of the radiation away from an incident path extending from the first aperture to the second aperture. The reflector array allows a second part of the radiation to continue along the incident path at a safe level towards the second aperture. Optionally, the reflector array blocks the incident path so that substantially no radiation passes to the second aperture if unsafe levels are detected.
