使用直接检测传感器的电子能量损失光谱仪
摘要：
本发明涉及一种电子能量损失光谱仪，包括一个直接检测传感器、一个高速快门及一个传感器处理器，其中所述传感器处理器用于将来自单个传感器读数的图像结合为一体并将来自所述传感器的二维图像转换为一维光谱，其中所述一维光谱输出至计算机，所述高速快门的操作与传感器成像的时间相结合；控制所述快门，从而允许减少对与单个传感器读数相应的图像的曝光。通过成像以不完全曝光的方式曝光多个图像，其中所述多个图像结合形成一个合成图像。多个图像由以不同的曝光时间曝光所述传感器形成的图像组成。
摘要（英）：

The present invention relates to an electron energy loss spectrometer comprising a direct detection sensor, a high speed shutter and a sensor processor, wherein the sensor processor is configured to combine an image from a single sensor reading into one and convert a two-dimensional image from the sensor into a one-dimensional spectrum,and the one-dimensional spectrum is output to a computer in which the operation of the high-speed shutter is combined with the time at which the sensor is imaged; the shutter is controlled so as to allow exposure to an image corresponding to a single sensor reading.Exposing a plurality of images by imaging in an incomplete exposure, wherein the plurality of images are combined to form a composite image. The plurality of images are composed of images formed by exposing the sensors at different exposure times.
