| 摘要 |
The invention relates to a spectrometric method and a spectrometer for analyzing optical radiation. The spectrometer comprises an optical means (G) capable of causing dispersion of an optical beam (L) to be measured when the beam strikes it, and detecting means (D1 ... DN) for detecting the intensity of several discrete wavelengths (l1 ... ln) of the dispersed optical beam. According to the invention the detecting means comprises an array of at least N detector elements (D1 ... DN) having outputs connected to connecting means (SW1 ... SWN, A1) to connect the output signals of the detecting means in N different combinations to form N different sum signals during one measuring period, where N is the number of discrete wavelengths to be analyzed. |
