介绍了一种使用面阵彩色ＣＣＤ 摄像机和体全息光栅设计的小型光谱仪。该光谱仪使用普通模拟视频信号输出格式，经过带有视频输入接口的计算机显示卡采集信号并实现图像信号的数字化，利用面阵彩色ＣＣＤ的二维图像特点采用软件去除背景噪声，在达到使用分辨率和精度要求的前提下降低了对ＣＣＤ 器件性能的要求。从而降低了整机的造价。利用特别设计的局部缩放机构和ＣＣＤ采集的色彩信息实现了对全光谱的频段细分，在有效像素数不变的情况下提高了系统的物理分辨率。
A miniature spectrometer designed with an area array color CCD camera and volume holographic grating is introduced. The spectrometer uses common analog video signal output format, through a computer graphics card with a video input interface to capture the signal and digitize the image signal, the use of two-dimensional image features of the area array color CCD software to remove the background noise, at the use of resolution And accuracy requirements of the CCD device under the premise of reducing the performance requirements. Thus reducing the overall cost of the machine. The use of specially designed local zooming mechanism and the color information collected by the CCD realize the subdivision of the full spectrum frequency band and improve the physical resolution of the system with the same number of effective pixels.
