We present a comparative study of the optical and dielectric anisotropy of a laterally fluorinated liquid crystal dimer and its homologous trimer, both exhibiting two nematic phases. In the high-temperature nematic phase, both oligomers exhibit posit

In this paper, we demonstrate analog phase modulation in a transmissive configuration using the flexoelectro-optic effect in short-pitch chiral nematic liquid crystal (LC) devices. Two different modes are considered, both of which are shown to genera

Preparation for the extreme range of lunar surface temperature is essential for the success of robot and human exploration on the Moon. Much research on this topic has been carried out over recent years. Generally, these approaches can be divided int

We present dynamic time-resolved measurements of a multi-pixel analog liquid crystal phase modulator driven at a 1 kHz frame rate. A heterodyne interferometer is used to interrogate two pixels independently and simultaneously, to deconvolve phase mod

In-Situ Resource Utilization (ISRU) is a good alternative to enable sustainability in lunar exploration. Toward this objective, Space Applications Services proposed to deploy multiple robots (IBIS, MANTIS, and a mobile gantry) on the Moon for ISRU. T

Recent advances in data storage technologies, such as optical storage and DNA storage, allow data storage for timescales of millions to billions of years. Alongside these developments, initiatives such as Lunar Mission One, the Long Now Foundation an
