Improved Illumination System of Laparoscope Using an Aspherical Lens Array
University of Arizona researchers have developed a more uniform illumination system for better medical images. The system directs outgoing rays from the fiber bundle to provide more uniform illumination, even with extended non-lambertian sources, allowing the full field of view to be fully observed with good detail. It is low cost and an be easily attached...

Multi-Resolution Foveated Laparoscope
Researchers at the University of Arizona have developed an optical design for laparoscopes that can obtain wide angle and high magnification images of a surgical area in real time. The two images enable seamless registration between the low and high-resolution images, providing surgeons with the best of both worlds. In addition, the innovation enables...
