偵測元件或儀器之反應時間，經常借助於較待測元件或儀器之反應速度更快的量測儀器獲得解答，但可能礙於成本或技術門檻考量，此種方式經常並不容易取得。反之，使用較低取樣速度規格之偵測器，透過特殊的取樣方式，也是可量測得正確的結果。
基於上述之想法，本研究使用頻閃之取樣概念，建立光源切換時間之量測方法。欲使用此取樣方式，必須要先知道量測儀器之量測行為，故本研究之前半部，透過實驗和建立量測儀器之量測行為模型，將得到之實驗數據，透過最小帄方誤差曲線擬合法，可以詳細推估光譜儀的量測特徵值，其中包含積分時間與傳遞時間。在本研究後半部，便利用得知量測行為之光譜儀，藉由等時取樣的方法，經由連續量測，重組得到之數據，最終量測到較量測週期短之光源切換時間。

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.
