Abstract

FMCW LiDAR is an optical measurement technology that is drawing attention in various industries. For 3D FMCW imaging, a proper beam scanning process is required. Since conventional mechanical beam scanners have limits in automotive FMCW LiDAR, active researches on solid-state beam scanners are ongoing. Despite advantages of solid-state beam scanners, there is a disadvantage in field of view (FOV) with current solid-state scanners. In this study, we conducted studies on extending the FOV of the solid-state FMCW LiDAR system. By applying a relay optical system, we achieved an extension in FOV of our system and 3D FMCW images are obtained.
