Abstract
Systems and methods provide for illuminating a subject using a light pipe that transmits light from a source. A method includes providing a light pipe, the light pipe defining an inner lumen through which the image sensor views the subject; providing a light source in alignment with a proximal portion of the light pipe; and using the light source, projecting a light into the light pipe and through the light pipe, the light pipe including a distal portion for providing a high-angle bright field illumination pattern on the subject with a first portion of the light and for reflecting a second portion of the light for providing a low-angle dark field illumination pattern on the subject.
