摘要

Abstract

Since flat optics has the feature to implement a compact system

they are widely used in various applications to replace bulky refractive optics. However

they suffer from chromatic aberrations due to dispersion

limiting their effectiveness to a narrow wavelength range. Consequently

diffractive optics has been applied for dynamic beam steering within a specific wavelength region or for static steering across multiple wavelengths. This limitation has made it challenging to implement dynamic beam steering in full-color display applications. To address this issue

we developed a multi-wavelength-based optical architecture that mitigates chromatic aberrations. This system incorporates color-selective retarders

half-wave plates

polarization plates

and beam deflectors. We experimentally demonstrated an achromatic beam deflector using a dynamic phase array in transmission mode

achieving continuous tunable beam steering over multiple wavelengths at 460

520

and 638 nm.
