Introduction

The field of image acquisition has undergone significant transformation over the years, driven by advancements in technology and the increasing demand for high-quality images in various applications [1]. Image acquisition encompasses a broad range of techniques designed to capture visual information from the environment [2,3]. From traditional methods to contemporary digital approaches, these techniques serve as the foundation for countless applications in scientific research, industrial inspection, medical imaging, and remote sensing [4,5]. The continuous evolution of image acquisition technologies reflects the need for more precise, efficient, and reliable imaging solutions that cater to the complex requirements of modern society [6].

At the heart of image acquisition lies the necessity for effective illumination techniques [7]. Proper lighting was essential for obtaining clear, high-contrast images, which can significantly affect the quality of the final output [8]. Advanced illumination strategies, such as structured light and multi-spectral illumination, enhance image quality by providing optimal lighting conditions tailored to specific imaging needs [9,10]. These methods allow for improved feature extraction, enabling researchers and practitioners to capture intricate details that traditional illumination techniques miss [11]. As a result, the choice of illumination plays a pivotal role in determining the success of image acquisition across various disciplines [12].
