Advantages:• Full frame TOF data captured with each laser pulse• Unambiguous direct calculation of range• Blur-free images without motion distortion• Co-registration of range and intensity for each pixel• Pixels are perfectly registered within a frame• Ability to represent objects that are oblique to the
camera• Low mass• No moving parts• Low power consumption• Various lens sizes and FOV possible• Eye-Safe laser assembly
