Research on Acquisition and Display Technology of Hyperspectral Imaging System Based on AOTF

为了提高声光可调谐滤波器(AOTF)与CMOS相机结合的新型成像光谱仪的图像采集与显示速率,提出了一种基于AOTF光谱成像的数据快捷处理技术。利用VC++编写的上位机通过USB的控制传输对光学探测接收元件MT9M001C12STM的积分时间、增益进行灵活的配置,并且实时的显示帧率,这样可以保证数据的传输速度和正确性。结果表明,该设计方法不仅可以快速准确的获取目标物进行实时的显示,而且成像质量良好。

In order to improve the speed of image acquisition and display of the new imaging spectrometer,which is based on the combination of acousto-optic tunable filter(AOTF)and CMOS camera,a fast data processing technique based on AOTF spectral imaging is proposed.By using PC based on USB and VC++,the integration time of the detector MT9M001C12STM can be controlled to configure the gain flexible and display the rate of frame in real-time,which can guarantee the data transmission speed and accuracy.The results show that this design method can not only obtain the real-time display of the target quickly and accurately,but also has good image quality.
