摘要:
A method and apparatus for optically recording dual images of the same body wherein a first image is reflected directly into a camera through a light discriminating filter, and a second image of the body is reflected into the camera through an optical path defined by an arrangement of reflective surfaces having a second light discriminating filter in the path such that the two images may be discriminated after recording.
