Range Finding using a Masked Annular Folded Optic Imager

Not Accessible

Your library or personal account may give you access

Abstract

High-resolution images of an unfocused laser beam were obtained by masking the aperture of an annular folded optic imager. Image processing yielded calibrated distance measurements correlated to the separation of the beam spots.
