【摘要】：针对夜天光包含的大量近红外辐射,本文从理论和实验上研究了基于近红外波段全透的红、绿、蓝滤光片的EMCCD真彩色成像方法。夜天光在近红外波段的能量均被EMCCD吸收,再结合EMCCD的电子倍增功能获得较高亮度和信噪比的红、绿、蓝分量图像,最终通过彩色融合等图像处理方法获得真彩色EMCCD图像。本文进行了全月、半月、1/4月和晴朗星光照明条件下的真彩色成像色彩仿真,在此基础上制作了彩色滤光片,测试了典型样本的光谱反射率,搭建了真彩色EMCCD实验装置并开展外场试验。工作结果表明:该方法获得了色彩丰富、空间深度感较好、信噪比较高的真彩色EMCCD图像。
[Abstract]:In view of the large amount of near-infrared radiation contained in night sky light, the EMCCD true color imaging method based on full-transparent red, green and blue filters in near infrared band is studied theoretically and experimentally in this paper. The energy of night sky light in the near infrared band is absorbed by EMCCD. The red, green and blue components of high brightness and signal-to-noise ratio (SNR) are obtained by combining the electron multiplication function of EMCCD. Finally, the true color EMCCD images are obtained by color fusion and other image processing methods. In this paper, the color simulation of true color imaging under the conditions of full month, half month, 1 / 4 month and clear starlight illumination is carried out. On this basis, the color filter is made, and the spectral reflectivity of typical samples is tested. The true color EMCCD experimental device was built and the field test was carried out. The results show that the true color EMCCD images with rich color, good spatial depth and high signal-to-noise ratio are obtained by this method.
