Two-dimensional optical scanning for large-field-of-view optical image generation applications

Abstract

Optical image generation is a very important step in many optical imaging system applications. However, current optical image generation systems (OIGS) produce a fixed simple grid image with a small field of view (FOV) because of the physical limitation of the OIGS itself. Here, we use proposed an optical image generation method using optical scanners to achieve a large FOV and images defined by the user. The combination of two scanners implements the two-dimensional optical scanning for obtaining the improvement of field-of-views (FOV) in two-dimensional (2D) directions. Here, three important findings, including scanning optical configurations, an analog-to-digital-based scanning pattern, and a scanning imaging model, of 2D optical scanning in the image generation with a large field of view are reported. The proposed method can improve the FOV with 20° in the 2D directions. These three results are very valuable references for the application of image generation. The proposed method has potential applications in multiple fields, such as camera calibration, computation imaging, and image compression.
