论文摘要

CMY颜色摄像机与RGB对应物的不同之处在于,它采用了青色,洋红色和黄色的减去色彩空间。 CMY摄像机在低光条件下往往比RGB摄像机的性能更好。然而,对于具有颜料和染料制成的常规CMY颜色过滤器技术的性能限制,对于具有子微米像素尺寸的下一代图像传感器的性能。这些常规的过滤器在纳米级尺寸上很难制造,因为它们使用其吸收特性减去颜色。本文介绍了CMOS兼容的纳米级厚CMY CMY颜色镶嵌物,由Al-Tio2-Al纳米棒制成,形成一个以CMYM模式排列的阵列8200万颜色的像素为4.4微米。然后将颜色镶嵌​​物集成到MT9P031单色图像传感器上,以制造CMY相机,并使用12颜色的Macbeth图表进行了颜色成像。开发的技术将在生物学和摄影中的天文学,低暴露时间成像中应用。

A CMY colour camera differs from its RGB counterpart in that it employs a subtractive colour space of cyan, magenta and yellow. CMY cameras tend to performs better than RGB cameras in low light conditions due to their much higher transmittance. However, conventional CMY colour filter technology made of pigments and dyes are limited in performance for the next generation image sensors with submicron pixel sizes. These conventional filters are difficult to fabricate at nanoscale dimensions as they use their absorption properties to subtract colours. This paper presents a CMOS compatible nanoscale thick CMY colour mosaic made of Al-TiO2-Al nanorods forming an array 0.82 million colour pixels of 4.4 micron each, arranged in a CMYM pattern. The colour mosaic was then integrated onto a MT9P031 monochrome image sensor to make a CMY camera and the colour imaging demonstrated using a 12 colour Macbeth chart. The developed technology will have applications in astronomy, low exposure time imaging in biology and photography.
