摘　　要：全光固体分幅相机技术是目前超快诊断技术领域最有前途的发展方向之一。因其在实现皮秒、亚皮秒量级时间分辨率、超高空间分辨率、拓宽探测信号波段范围、可靠性、稳定性、抗辐射抗干扰等方面拥有独特的优势,引起了人们的广泛关注。文中将波分复用以及偏振复用技术应用到全光固体分幅相机系统中,进行多分幅的方案研究,在保证皮秒量级时间分辨率的前提下,探索获得几幅到十几分幅数的分幅方案。最终,在实验上获得了空间分辨达到60 lp/mm的四分幅图像。实验结果显示,对于波分分幅的时间分辨率为1.414 ps,偏振分幅的时间分辨率为15 ps。All-optical solid framing camera technology is one of the most promising areas with the best develop-ing future in ultrafast diagnosis technology. The technology is widely paid attention due to the unique advantages oftime resolution realization at picosecond and sub- picosecond level, ultra- high spatial resolution, broadening thewaveband range of detection signals, reliability, stability, anti-jamming and anti-radiation. Wavelength division mul-tiplexing and polarization multiplexing technologies are applied to the all-optical solid framing camera system to themulti-framing schemeresearch. Under ensuring picosecond level time resolution, the framing schemes of acquiringseveral to tens of pieces of frames are explored. Four pieces of framing images with 60 lp/mm spatial resolutions areobtained through experiments. Experimental results show that time resolution of wave division framing is 1.414 psand time resolution of polarization framing is 15 ps.
