    摘要： An imaging system illuminates an object with infrared light to enhance visibility of buried structure beneath the surface of the object, and projects a visible light image of the buried structure onto the surface of the object. The system may include an infrared light source for generating the infrared light and a structure for diffusing the infrared light. The diffusing structure may include one or more layers of diffusing material for diffusing the light. The system further includes a video imaging device for receiving the infrared light reflected from the object and for generating a video image of the buried structure based on the reflected infrared light. The buried structure may be a subcutaneous blood vessel. A calibration procedure is described as well as embodiments for ensuring that the object is maintained in focus at the correct distance.
