Large Aperture Agile Scanning Mirror

New large aperture wide beam steering device is proposed. This device is based on specific type of liquid crystal technologies and expected performance is not only wide beam steering, but also fast enough steering without using any mechanical moving parts. Unlike typical liquid crystal based technologies, this particular technology would enable polarization free beam steering. This gives more light throughput efficiency. Although most of liquid crystal technologies require single linearly polarized light switching, newly developing liquid crystal driving mode technology would enable up to 90% use of incident non-polarized light. This project includes couple of challenging technical development such as polarization-free switching, fast enough optical response (~ 1 ms) and wide enough beam steering. Fast optical response will be realized by i-CORE's specific liquid crystal material technologies, and wide beams steering will be realized by large spatial distribution of liquid crystal refractive indices in conjunction with specific integrated liquid crystal panel design such as fine pitch patterned electrode structures, and/or blazed grating structures.
