Abstract

One or more techniques and/or systems are disclosed for effectively illuminating a target. The target may be in a confined field of view area. Such systems may mitigate shadows and lack of light homogeneity at surgical procedure settings, research sites, or other localized areas where humans may operate in a confined field of view area. One or more lighting modules can be disposed in a target area, for illumination of one or more illumination target locations in the confined field of view. An object detection component can detect an object or desired target in the target field of view location, and provide data indicative of the detected object/target to an illumination module adjustment component. Based on the data indicative of the detected object/target, the illumination module adjustment component can provide data indicative of an illumination adjustment to the first illumination module to provide desired illumination.
