Method and Demonstration of True-Color Imaging by EMCCD
摘要
Abstract
In the light of a great deal of near-infrared radiation in the night sky, the true-color imaging method of EMCCD based on the red, green and blue optical filters with all fully transmitting NIR is studied through experiment and theory in this paper. EMCCD with electron multiplier function, can take full use of near infrared radiation in the night sky, and obtain the images of red, green, and blue channel with high brightness and signal-to-noise ratio. Ultimately, true-color EMCCD image can be obtained through comprehensive image processing methods including the color image fusion. This article makes color simulation under the conditions of the full-moon, half-moon, quarter-moon and bright-star night sky and carries out a series of studies on the production of color filters, the spectral reflectance measurement of samples, the construction of true-color EMCCD experimental device and the field tests. The experimental results show that based on the method in this paper, true-color EMCCD images with rich color, good spatial depth and high signal-noise ratio can be obtained successfully.关键词
