Abstract

This paper presents a method for optimizing spectral imaging based on incoherent correlation holography. By adjusting the axial position of the PZT, a series of interference patterns with varying optical path differences (OPD) is captured. Due to the limited precision of the PZT, we propose an optimization algorithm capable of accurately retrieving the intensity variation. Following the Fourier transform to the image stack, the spatial wavefront corresponding to different wavelengths can be reconstructed. We demonstrate the effectiveness of our approach through spectral reconstruction under quasimonochromatic illumination, while also highlighting the potential for multi-spectral imaging applications.
