Abstract

Traditional liquid prisms face challenges in achieving large aperture and wide deflection angle. In this letter, a large aperture liquid prism with mechanical drive is proposed. Four baffle plates are used in the prism cavity to achieve rigid constraints on the movement of the deflector at the L-L interface. The proposed device achieves the deflection of one-dimensional FOV with a large aperture of 16 mm and a deflection angle of 7.4°(±3.7°). The proposed device can also realize two- dimensional scanning by stacking two identical prisms together. This work addresses key limitations of existing liquid prisms, providing new solutions for applications in optical scanning, imaging, and adaptive systems.

大口径液体棱镜，扩展偏转范围

传统的液体棱镜在实现大口径和宽偏转角度方面面临挑战。本文提出了一种机械驱动的大口径液体棱镜。在棱镜腔中使用了四个挡板，以实现对偏转板在L-L界面处运动的刚性约束。该装置实现了一维视场的偏转，孔径为16 mm，偏转角度为7.4°（±3.7°）。该装置还可以通过将两个相同的棱镜堆叠在一起来实现二维扫描。这项工作解决了现有液体棱镜的关键局限性，为光学扫描、成像和自适应系统的应用提供了新的解决方案。

期刊介绍： IEEE Photonics Technology Letters addresses all aspects of the IEEE Photonics Society Constitutional Field of Interest with emphasis on photonic/lightwave components and applications, laser physics and systems and laser/electro-optics technology. Examples of subject areas for the above areas of concentration are integrated optic and optoelectronic devices, high-power laser arrays (e.g. diode, CO2), free electron lasers, solid, state lasers, laser materials'' interactions and femtosecond laser techniques. The letters journal publishes engineering, applied physics and physics oriented papers. Emphasis is on rapid publication of timely manuscripts. A goal is to provide a focal point of quality engineering-oriented papers in the electro-optics field not found in other rapid-publication journals.
