Non-Uniform Scanning Method with Restoration Error for Laser Imager

Abstract

Laser imagers using KTN crystals require a large number of observations to obtain high-resolution images, resulting in long measurement times. In this paper, we propose a method to perform appropriate dot scanning by determining the probability density distribution of the next scan based on the results of previous scans and their restoration result. Compared to randomly scanned images with uniform weights, the proposed scanning method produces more accurate processing results.
