ABSTRACT:
The present invention provides new projection schemes for wide angle imaging lenses rotationally symmetric about optical axis wherein the field of view of lenses and the size of image sensors are directly reflected without any reference to the effective focal length of the lenses. This invention also provides explicit examples of wide-angle lenses implementing the newly developed projection schemes. According to the present invention, by providing new projection schemes explicitly reflecting the physical quantities of direct interest to the user for industrial applicability, namely, the field of view and the image sensor size, it is possible to realize wide-angle lenses providing the most satisfactory images.
