ABSTRACT:
The invention according to a first aspect may include an optical system. The optical system may have an axial axis. This optical system may have a number of primary mirror segments. A number of reflectors may be arranged about the axial axis. The primary mirror segments may be configured to reflect a number of principal rays along a first set of chords to corresponding reflectors. These reflectors may be configured to reflect the corresponding principal rays along a second set of chords. Both the first set of chords and the second set of chords may have an angle in excess of 45 degrees with respect to the direction of the axial axis. The invention according to a first aspect may also include a second set of reflectors. The second set of reflectors may be configured to direct the light to an image plane. Other aspects of the invention may include a method of receiving light using an optical system configured to spiral light though the system and a method of making such a system.
