Abstract
PURPOSE: To obtain orthographic images by providing a paraboloid of revolution reflector behind the sutter device.
CONSTITUTION: It is assumed that one of the shutter means of a shutter device S opens and a light transmission portion or opening S0 is formed. The ray q1 parallel to the optical axis l out of the light at the point P1 on an object N passes through the sutter device S, is reflected by a reflector M and reaches a photosensitive element U. However, the ray q1 which is not parallel does not reach the element U because the other shutter means are not open. If it is assumed that the ray q2 of the point p2 on the object N passes through the opening S0, this ray q2 does not reach the photosensitive element U because it is not parallel to the optical axis l. Namely, only the parallel ray at one point P1 on the object N is captured by the photosensitive element.
