Imaging through scattering remains a fundamental challenge in optical systems, with applications in atmospheric and astronomical imaging. We present Array Beam-Driven Computational Imaging through Thin Scattering Layer (ABD-CI-TSL), an experimental method using temporally coherent and spatially incoherent array beams to image through thin scattering layers. Object information is encoded onto the array beam, propagated through the scatterer, and recovered via deconvolution of the recorded point spread function. The method is evaluated across varying scattering conditions and axial locations. Results demonstrate that array beams preserve object spatial features under scattering, though reconstruction fidelity degrades with increasing scattering strength, highlighting ABD-CI-TSL's potential for scattering media applications.
