Abstract
Optical phased array (OPA) is a promising solid-state beam steering method. However, small scanning field of view (FOV) and grating lobes aliasing constraint its applications. Therefore, an omnidirectional all-solid-state aliasing-free scanning method which is implemented by two-dimensional liquid crystal OPA and conical mirror is presented. Experimental results demonstrate desired scanning with FOV of 360° × 1.1° and scanning error is less than 0.2° × 0.03°, without moving parts and grating lobes aliasing.
期刊介绍：
Optics and Lasers in Engineering aims at providing an international forum for the interchange of information on the development of optical techniques and laser technology in engineering. Emphasis is placed on contributions targeted at the practical use of methods and devices, the development and enhancement of solutions and new theoretical concepts for experimental methods.
Optics and Lasers in Engineering reflects the main areas in which optical methods are being used and developed for an engineering environment. Manuscripts should offer clear evidence of novelty and significance. Papers focusing on parameter optimization or computational issues are not suitable. Similarly, papers focussed on an application rather than the optical method fall outside the journal''s scope. The scope of the journal is defined to include the following:
-Optical Metrology-
Optical Methods for 3D visualization and virtual engineering-
Optical Techniques for Microsystems-
Imaging, Microscopy and Adaptive Optics-
Computational Imaging-
Laser methods in manufacturing-
Integrated optical and photonic sensors-
Optics and Photonics in Life Science-
Hyperspectral and spectroscopic methods-
Infrared and Terahertz techniques
