Abstract
A system and method for designing and using freeform reflectors to collect images of a wide angle field-of-view scene is provided. A freeform reflector may enable a wide angle field-of-view to be collected in an unwarpped and unwrapped manner such that computer processing may be eliminated. Furthermore, the use of a freeform reflector allows for larger areas of an image sensor chip to be used, thereby providing higher resolution images. Because freeform reflectors may be configured to map a scene onto the image sensor chip in a scalar and mathematically correct manner, output images may be directly displayed from the image sensor chip. Wide angle field-of-view imaging systems, such as surveillance, alarm, and projector system, may utilize freeform reflectors as provided herein.
