We present a unified encoding approach for the generation and dynamic control of optical Airy beams using phase-only holography. By co-encoding a modified Airy beam Fourier spectrum together with an in situ Fresnel lens phase function into a single phase mask, the proposed method enables compact, lensless beam formation without external Fourier optics. While SLM-based implementations combining cubic and Fresnel phase profiles have been previously reported, the present work refines this strategy through an optimized 8-bit grayscale phase mapping procedure that improves phase accuracy and beam reconstruction quality. In addition to controlled spatial translation and angular steering, the method allows modulation of the beam’s effective acceleration through systematic adjustment of the cubic phase parameters, enabling dynamic reshaping of the parabolic propagation trajectory. Quantitative characterization of diffraction efficiency, beam fidelity, and background suppression confirms the improved optical performance of the proposed phase-only implementation relative to conventional phase–amplitude approaches. This digitally programmable and mechanically stable framework provides a compact and efficient platform for structured light generation and controlled beam shaping, with potential applications in optical manipulation and free-space optical communication.
