据报道，应用于荧光和喇曼光谱学的高灵敏度ＣＣＤ阵列比现有光电二极管列阵的噪声性能高４０多倍。据Ｐａｕｌ Ｇａｌｌａｇｈｅｒ工程师说，应用于光谱学的典型光电二极管列阵在室温下噪声场大约有１５００个电子，而新型ＣＣＤ提供的噪声场仅有３５个电子．它能大大地提高
It has been reported that high-sensitivity CCD arrays for fluorescence and Raman spectroscopy are more than 40 times more noise-efficient than existing photodiode arrays. According to Paul Gallagher engineer, the typical photodiode array used in spectroscopy has a noise field of about 1500 electrons at room temperature, whereas the new CCD provides only 35 electrons. It can be greatly improved
