Abstract

Abstract. Focus-tunable liquid lenses are used in various applications due to their compact size, light weight, low power consumption, and cost effectiveness. They have the potential for use in space applications, such as focus compensation, optical communications, and imaging systems. However, liquid lenses have not yet been evaluated for use in the space environment. This work focuses on characterizing operational differences of commercially available liquid lenses from Corning Varioptic and Optotune between Earth gravity, microgravity, and hypergravity environments. Results show a linear drift in the tip/tilt of 0.80 and 4.20 mrad going from 1 to 0 g for the Corning Varioptic A-39N0 lens and Optotune EL-16-40-TC-VIS lens, respectively, with lower optical aberrations in microgravity. Additionally, a significant but small increase in focal power going from 1 to 0 g by 0.02 D is observed for the Optotune lens. No significant change in focal power is observed for the Corning Varioptic lens tested in this experiment. Additionally, potential multi-beam interference is observed in defocus patterns of the Corning Varioptic lens tested during the experiment.

商用液体透镜组件在微重力环境下的光学性能

摘要。可调焦液体透镜因其体积小、重量轻、功耗低和成本效益高而被广泛应用于各种领域。它们有可能用于空间应用，如聚焦补偿、光通信和成像系统。然而，尚未对液体透镜在太空环境中的应用进行评估。这项工作的重点是鉴定康宁 Varioptic 和 Optotune 公司的市售液体透镜在地球重力、微重力和超重力环境下的运行差异。结果表明，康宁 Varioptic A-39N0 镜头和 Optotune EL-16-40-TC-VIS 镜头在微重力环境下的光学像差较低，从 1 g 到 0 g 的尖端/倾斜度线性漂移分别为 0.80 和 4.20 mrad。此外，Optotune 镜头的焦距功率从 1 g 到 0 g 显著但微小地增加了 0.02 D。本实验中测试的康宁变光透镜的焦距功率没有明显变化。此外，在实验中测试的康宁变焦镜头的散焦模式中也观察到了潜在的多光束干扰。
