Abstract
A panoramic imaging system for projecting a 360 degree cylindrical field of view onto a two-dimensional annular format has a panoramic imaging block with a concentric axis of symmetry, two refractive surfaces and two reflective surfaces. The first reflective surface is a concave conicoid of revolution with the conic constant in the range from -0.6 to +2.0. In an embodiment of the invention, the second refractive surface (the last in the path of rays) is flat, while the first reflective surface, the second reflective surface and the first refractive surface are all spherical.
