There is a big difference in the appearance of the acquired images.
\nThe RDL lens is an ultra-wide-angle lens with a horizontal angle of view of 120\u00b0 and distortion of less than 2%, thanks to our proprietary optical design technology.<\/p>\n

General wide-angle lenses used for LiDAR, such as fisheye lenses, cause distortion as if the center of the image is stretched toward the edges, resulting in compression of the peripheral images.<\/p>\n

The projection method (f\u03b8 or ftan\u03b8) is also different as shown below.<\/p>\n
