Human/insect lens adds depth to wide-angle views

Facebook X LinkedIn Email
A new lens that combines the focusing ability of the human eye with an insect’s wide-angle view could improve surgical imaging or help make a confocal microscope with no moving parts. “Our eye can change focus. An insect eye is made of many small optical components that can’t change focus but give a wide view. We can combine the two,” said Dr. Yi Zhao, associate professor of biomedical engineering and ophthalmology at The Ohio State University. “What we get is a wide-angle lens with depth of field.” Zhao’s prototype lens is made of a...Read full article

    digital camera
    A camera that converts a collected image into pixels that are black or white digital or shades of gray. The digital data may then be manipulated to enhance or otherwise modify the resulting viewed image.
    fixed focus
    Describes devices that are not provided with a means of focusing.
    optical component
    One or more optical elements – typically cemented together - in an optical system that are treated as a single group; e.g., a beamsplitter, or a cemented doublet or triplet.
