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 can be easily...
