An in vivo imaging device having an illumination system that creates a virtual source within a tissue region of a subject in a non-invasive manner. The illumination system transforms a maximum amount of illumination energy from a light source into a high contrast illumination pattern. The illumination pattern is projected onto the object plane in a manner that maximizes the depth to which clear images of sub-surface features can be obtained. The high intensity portion of the illumination pattern is directed onto the object plane outside the field of view of an image capturing device that detects the image. In this configuration, scattered light from within the tissue region interacts with the object being imaged. This illumination technique provides for a high contrast image of sub-surface phenomena such as vein structure, blood flow within veins, gland structure, etc.
An apparatus for detecting optical characteristics of a sub-surface object located in the region of an object plane, comprising:
A spectral imaging apparatus for non-invasive, in vivo imaging of a subject's tissue and blood, comprising:
A method for creating a source of illumination in a sub-surface region of an object that contains an area of interest, wherein the area of interest is illuminated from all directions about an object plane wherein the object is located, wherein an image of the area of interest is detected by an image capturing device, comprising the steps of:
A spectral imaging apparatus for non-invasive, in vivo imaging of mammalian tissue and blood in a living body, comprising:
