specific Embodiment approach 1
[0019] Specific implementation mode 1. Combination figure 2 and image 3 Illustrate this embodiment, the realization method of the space-borne imaging spectrometer based on multi-channel EMCCD, this method is realized by the following steps:
[0020] Step 1. The optical signal enters the spectrometer optical system through the telescope optical system and then outputs it through the multi-channel EMCCD;
[0021] Firstly, it is stipulated that the sensor of the imaging spectrometer is an area sensor structure, and the number of columns is the minimum number of pixels per row of the sensor n mini According to the formula: OK; the minimum number of sensor lines of the imaging spectrometer is equal to the number of bands n of the imaging spectrometer 谱段 ; The signal output by each line of the sensor of the imaging spectrometer is read out simultaneously by m channels, and the total output channel number of the sensor of the imaging spectrometer is p 通道 By the formula m×n 谱段...
