Abstract
Disclosed is a hand-held optical apparatus and method for using the apparatus to activate and detect optical emissive materials as part of a safety interlock system. Typically, the hand-held optical apparatus will include one or more light sources capable of emitting at least one wavelength of light towards an optical emissive material, a light detector capable of detecting a response from the optical emissive material, and control circuitry configured to cause at least one of the one or more light sources to emit the at least one wavelength at a power density less than a predetermined threshold, receive a signal from the light detector representing a detected response, and repeat until the microprocessor determines the detected response matches an expected response.
