Abstract
The Laser Line Identifier (LLI) is a real-time device which can indicate wavelengths of the laser radiations. LLI mainly consists of a beam splitter, narrow bandwidth transmission filters and detectors. The filters and the detectors form a unique pair so that a signal detected at a particular detector can only mean the radiation of a certain wavelength. The detectors are hardwired to a set of indicators such as a set of colored lights or a voice recording so that the wavelength of the radiation is clearly indicated even to a non-technical person.
