ABSTRACT

After working for a period of time, the optical performance of the ship's deck-embedded lamps may be attenuated, directly affecting the ship navigation and even helicopter’s take-off and landing, so it is necessary to measure its optical characteristics frequently. Due to the disassembling difficulty and limited space for the ship's deck-embedded lamps, the traditional optical testing methods are difficult to apply. Based on the purpose of overcoming its implementation difficulty, the optical performance testing technology of deck-embedded lamps has been studied in this paper. The scheme design and physical realization of a portable device for deck-embedded lamps’ intensity testing have been completed, including designs of mechanical structure, hardware circuit and software algorithm. The results show that the testing device can provide an environment that eliminates natural light interference, realizing the measurement, judgment and display of the optical characteristics of ship's deck-embedded lamps. The effectiveness of the device and the feasibility of the method have been verified.
