Hemispherical Confocal Imaging
We propose a new imaging method called hemispherical confocal imaging to visualize clearly a particular depth in a 3-D scene. The key optical component is a turtleback reflector which is a specially designed polyhedral mirror. To synthesize a hemispherical aperture, we combined the turtleback reflector with a coaxial camera and projector, to create on a hemisphere many virtual cameras and proje...
متن کاملHemispherical Confocal Imaging Using Turtleback Reflector
We propose a new imaging method called hemispherical confocal imaging to clearly visualize a particular depth in a 3-D scene. The key optical component is a turtleback reflector which is a specially designed polyhedral mirror. By combining the turtleback reflector with a coaxial pair of a camera and a projector, many virtual cameras and projectors are produced on a hemisphere with uniform densi...
متن کاملA hemispherical imaging camera
Most of the existing panoramic cameras have cylindrical field of view (FOV) which has a 360 width in azimuth, but a limited height in elevation. However, a hemispherical (or near spherical) FOV is highly desirable in many applications such as robot navigation and surveillance. This paper presents a planarmirror-based panoramic camera (HEM) which is capable of acquiring nearly hemispherical FOV ...
متن کاملCombining Confocal Imaging and Descattering
In translucent objects, light paths are affected by multiple scattering, which is polluting any observation. Confocal imaging reduces the influence of such global illumination effects by carefully focusing illumination and viewing rays from a large aperture to a specific location within the object volume. The selected light paths still contain some global scattering contributions, though. Desca...
متن کاملHigh-speed multispectral confocal imaging
A new approach for generating high-speed multispectral images has been developed. The central concept is that spectra can be acquired for each pixel in a confocal spatial scan by using a fast spectrometer based on optical fiber delay lines. This concept merges fast spectroscopy with standard spatial scanning to create datacubes in real time. The spectrometer is based on a serial array of reflec...
