波长可调谐凝视型高光谱成像技术研究

Research on Wavelength-tunable Staring Hyperspectral Imager Technology

目前高光谱成像技术已经在遥感、探测等各个领域得到了广泛应用,但是在医学、材料学和微电子学等新兴学科领域,被动式成像方式自身却存在一些局限性和不适用性。探讨了一种波长可调谐的凝视型高光谱成像系统。使用波长可调谐的单色光实现了对被拍摄物体的快速光谱测量,并利用光栅作为分光元件,使该系统的兼容性和拓展性得到了极大提高。该研究对于类似成像系统的设计具有一定的参考和借鉴意义。

At present, the hyperspectral imaging technology is widely used in the fields of remote sensing and detection etc. However, in some emerging fields of medicine, material and microelectronics, the passive imaging method has its limitation and unsuitability. A wavelength-tunable staring hyperspectral imaging system is discussed. By using wavelength-tunable monochromatic light, the spectra of an object to be imaged is measured rapidly. In addition, because a grating is used as a light-splitting element, the compatibility and robustness of the system are improved greatly. This research is of reference value to the design of similar imaging systems.
