DUAL PRISM AND DUAL CAMERA USING THE SAME

摘要

PURPOSE: A dual prism and a dual camera using the same are provided to simultaneously image the same object on CCD by applying the dual prism of the simple structure to the dual camera and using two CCD. CONSTITUTION: A dual prism includes a first prism and a second prism. The first prism(3) includes an incident side(3a) and a first output side(3b). The second prism(5) includes a second output side(5a). The first prism includes a slope side having a predetermined gradient to the incident side. The second prism includes a slope side having a predetermined gradient to the second output side. The slope side of the first prism is opposite to the slope side of the second prism. The slope sides of the first prism and the second prism are used as branch sides. An angle between the incident side and the branch side is less than 45 degrees.
