The utility model relates to a beam phase-adjusting and direction-adjusting device, which comprises a functional core with a columnar through-hole and a driving core; a liquid phase-adjustable and phase-adjustable functional cavity is formed between the functional inner core and two cover plates installed at its left and right ends, and the functional cavity is composed of a phase-adjusting cavity and a direction-adjusting cavity, where the first liquid, the second liquid and the third conductive liquid are placed, and the three conductive liquids are not compatible with each other. With different refractive index, the phase modulation cavity is made of inelastic materials; the direction modulation cavity is made of four conductive materials bonded by insulating and gluing; the driving core is provided with a driving cavity with an elastic wall, with openings at both ends connected with the phase modulation cavity through a micro-channel, and the first liquid and the second liquid are stored; the outer side of the driving core is provided with a coarse-tuning driving device and a fine-tuning driving device. The utility model combines two functions of phase modulation and direction modulation in the same device, which solves the problem of common phase of optical synthetic aperture. Because complex devices such as electrodes are not needed, the measuring and calculating process is very simple.
【技术实现步骤摘要】
一种光束调相调向装置
本技术涉及一种光束调相调向装置,属于光学综合孔径、光电信息集成器件、微流控光学分析和自适用光学
技术介绍
光学综合孔径技术是将多个小口径的光学镜面或光学系统按照一定的空间位置排列,通过光路、镜面的调整和相位匹配,使得通过各个子孔径的光束在共同焦平面上满足同相位要求,以实现光场的相干叠加,达到与之通光口径相当的单一大口径系统的衍射分辨率。目前光学综合孔径技术已经成为增大望远镜口径、提高望远镜分辨率的一种重要手段。子孔径间能否良好共相的问题制约着光学综合孔径望远镜的光学性能。实际上,共焦易于实现,难点在于共相。针对拼接型望远镜共相难的问题,文章《基于色散条纹传感技术的拼接镜共相方法》提出了一种基于色散条纹传感技术的共相误差检测方法,硕士论文《自适应光学合成孔径成像遥感器中光纤压电陶瓷移相器的研究》使用光纤压电陶瓷移相器来对相位误差进行实时测量与校正,硕士论文《光学综合孔径望远镜中电感式位移传感器的研究》使用的传感器具有一定的线性度、灵敏度和分辨率的,可用于综合孔径望远镜子孔径间位移测量系统。
