Reporters obtained the following quote from the background information supplied by the inventors:“There are many potential applications for rapid non-contact q uantitative distance measurement/mappingin autonomous vehicles (such as self-dr iving cars), robotic vision, virtual/augmented reality displays, 3Dscanning and printing, and biomedical applications, among many others. Previous and current generationlight detection and ranging (LiDAR) systems developed for automotive sensing seek centimeter- todecimeter-scale resolution over tens to hundreds of meters range, for which pulse-echo time-of-flight imagingusing direct amplified detection is sufficient and which currently dominates the landscape. Although such systems achieve near video resolution and update rate, the direct detection approach limits the detectionsensitivity and dynamic range and thus makes these systems sensitive to low reflectance objects andbright ambient light.
