Description
Summary:碩士 === 國立中央大學 === 光電科學研究所 === 98 === As to measure the response time of the components and/or the instruments, it usually uses another instrument with much faster response time. Because of the consideration in the cost or the technique levels of the required equipments, it might be not very feasible to adopt the conventional methodology. On the other hand, the fast changing characteristics could be recovered by utilizing the detectors with slower sampling rate based on the stroboscopic methodology. On the basis of the idea of the stroboscopic concept, it is very helpful to further establish a experiment for detecting the responses of the on-off light sources. In the first part of this work, an empirical model has been established for characterizing the detectors in use. With aid of the lease square error fitting, two important parameters of the spectrometer have been explored. They are two characteristic time intervals. One is the integration time for signal detection and the other is the time duration for the data communication with other instruments. In the last part of this work, the characterized spectrometer is applied for the monitoring on the on-off light sources. Accordingly, the quicker changing behaviors of the on-off light sources are successfully recovered with the slow response detector.
