鬼成像相较于传统光学成像有着高分辨力、 抗噪声能力强等优势。而相较于单一波长鬼成像,多波长鬼成像在对待测物体空间信 息进行重构的同时,还可以重构其色彩信息。首先简要介绍了多波长鬼成像的理论基础, 随后以白光照明的多波长鬼成像为实验架构,选用哈达玛照明图样进行了多波长鬼成像的 色彩重构。并通过扩大光谱范围,即采用多个波长进行优化实验,使重构结果中的色彩明亮度得 到了改善。该研究的开展为多波长鬼成像在光谱成像方面实现应用化奠定了基础。

Compared with traditional optical imaging techniques, ghost imaging has the advantages of high resolution and strong anti-noise capability. While compared with single-wavelength ghost imaging, multi-wavelength ghost imaging can not only reconstruct the spatial information of the target object to be measured, but also reconstruct its color information. Firstly, the theoretical basis of multi-wavelength ghost imaging is briefly introduced. Then the color reconstruction of the multi-wavelength ghost imaging is carried out by using Hadamard illumination pattern with the multi-wavelength ghost imaging with white illumination as the experimental architecture. The optimization experiment of expanding the spectral range is proposed, that is, increasing types of the wavelength, which improves the color brightness of the reconstructed image experimentally. It is believed that the research is helpful for the practical applications of multi-wavelength ghost imaging in the field of spectrum imaging.
