Combined optimization ghost imaging based on random speckle field (2403.03426v1)
Published 6 Mar 2024 in physics.optics and eess.IV
Abstract: Ghost imaging is a non local imaging technology, which can obtain target information by measuring the second-order intensity correlation between the reference light field and the target detection light field. However, the current imaging environment requires a large number of measurement data, and the imaging results also have the problems of low image resolution and long reconstruction time. Therefore, using orthogonal methods such as QR decomposition, a variety of optimization methods for speckle patterns are designed combined with Kronecker product,which can help to shorten the imaging time, improve the imaging quality and image noise resistance.
