Optimizing approach of wavefront aberration in the recording of holographic lens based on spatial light modulator

A novel method is presented to optimize recording wavefront aberration of holographic lens (HL) based on spatial light modulator (SLM). According to the theory of wavefront aberration, aberration characteristics and expressions are obtained, and one-dimensional aberration curves are drawn, and optimizing approach of holographic lens based on SLM is proposed. We theoretically analyze the approach of reducing aberrations by recording the holographic lens via single exposure with a hologram loaded on the SLM. The effect which zero-order crosstalk of the SLM does to the holograms as well as the stop surface of the field of view does to the aberrations is discussed. Using the optimized hologram containing the aspheric information, we design the experiment of recording the holographic lens based on the SLM, and the result is consistent with the theoretical analysis.
