Light detection and ranging (LiDAR) sensor is widely recognized as a critical component for
accurate perception. However, there are a host of challenges that impede their performance …

Imaging systems are widely used in many fields. However, there is an inherent compromise
between field of view (FOV) and resolution. In this paper, we propose an optofluidic zoom …

Photoalignment technology enables macroscopic alignment of liquid crystalline molecules
and their aggregates in a non-contact process by irradiating photo-responsive liquid …

In this study, a highly-integrated optical module based on micro-electromechanical system
(MEMS) mirror, glass with low thermal expansion coefficient, a higher-order aspheric lens …

An accurate method to model the optical behaviour of liquid crystal (LC) devices, particularly
suited to devices where diffractive effects are present is described here. An accurate …

Telescopes play an essential important role in the fields of astronomical observation,
emergency rescue, etc. The traditional telescopes achieve zoom function through the …

We propose, optimize, fabricate and test beam-steering elements based on double-sided
liquid-crystal (LC) metasurfaces allowing for diffractive and spectral multiplexing, and thus …

In this paper, a 2D angle amplifier based on peristrophic multiplexed volume Bragg gratings
is designed and prepared, in which a calculation method is firstly proposed to optimize the …

We report refraction-type non-mechanical beam steering using a 100 μm thick swelling
liquid crystal (LC) gel film with a polymer concentration gradient, in which an electrically …

For vehicles or airborne displays, the limited space and arrangement of operating devices in
the cockpit often result in drivers having a certain off-axis viewing angle with the display …
