Photoluminescence built-in-test for optically initiated systems |
摘要 |
A built-in-test capability is provided for determining the integrity of an optical fiber connecting: (a) an optical firing unit having a primary light source emitting a first wavelength, a test light source emitting a second wavelength different from the first wavelength, a mechanism both for coupling light from the light sources to the optical fiber and also for coupling the return light to a filter/detector; and (b) an optically initiated device which is coupled to a second end of the optical fiber. The apparatus includes a photoluminescent material disposed at a junction of the optically initiated device and the optical-fiber-second-end. This photoluminescence material photoluminesces at a third wavelength (when exposed to the test light source), and the light travels through the optical fiber and, when detected indicates optical fiber continuity.
