Abstract We investigate the potential of using electrically tunable liquid crystal lenses (TLCLs) to record the activity of small animals in the Canadian Arctic. This suggests extreme temperature conditions that may dramatically change the TLCL’s parameters. Our analysis is performed on the example of “modal-control” TLCLs. Temperature dependences of main parameters are presented for TLCLs made with 5CB and ultra-low viscosity LCs. We finally propose an approach allowing to “athermalize” such lenses by adjusting certain control parameters, to maintain good optical performance. Other factors and limitations that affect the lens performance with temperature change are also discussed.

极端温度条件下的电可调液晶透镜

摘要 我们研究了使用电可调液晶透镜 (TLCL) 记录加拿大北极地区小动物活动的潜力。这表明极端温度条件可能会显着改变 TLCL 的参数。我们的分析是在“模态控制”TLCL 的示例上进行的。显示了由 5CB 和超低粘度 LC 制成的 TLCL 的主要参数的温度依赖性。我们最终提出了一种方法，允许通过调整某些控制参数来“无热化”此类镜头，以保持良好的光学性能。还讨论了影响镜头性能随温度变化的其他因素和限制。
