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.

L'invention concerne un dispositif d'imagerie in vivo comprenant un système d'illumination qui produit une source virtuelle à l'intérieur d'une région des tissus d'un sujet, selon un mode non invasif. Ce système d'illumination transforme une quantité maximale d'énergie lumineuse provenant d'une source lumineuse en un motif d'illumination à contraste élevé. On projette ce motif lumineux sur un plan objet de manière à agrandir la profondeur permettant de réaliser des images sub-superficielles nettes. La portion haute intensité du motif lumineux est dirigée sur le plan objet situé hors du champ du dispositif de saisie d'image qui détecte l'image. Dans cette configuration, la lumière diffusée depuis l'intérieur de la région des tissus interagit avec l'objet visualisé. Cette technique d'illumination permet d'obtenir une image à contraste élevé de phénomènes sub-superficiels tels que la structure veineuse, le flux sanguin dans les veines, la structure glandulaire etc.
