In this paper, we present a novel method for the measurement and the application of compensation holograms using spatial light modulators. 1. Introduction. Spatial light modulators
In the first part of this review, we survey key developments in metalens design that address long-standing challenges in optics, including chromatic aberration, high-numerical-aperture
The spatial light modulator (SLM) Holoeye LC-R720 is based on LCoS (Liquid Crystal on Silicon) technology. Due to the induced curvatures on the silicon plate by the production process, there are

To address these issues, a holographic optical system using a spatial light modulator (SLM) is typically employed to apply compensatory phase adjustments, correcting depth-dependent
