Image generator and projector
First Claim
1. A generator for generating a target image for testing sensing apparatus comprising:
- an aperture stop located adjacent to the sensing apparatus under test,a spherical mirror having a concave side facing the aperture stop,an object disposed between the spherical mirror and the aperture stop, wherein;
a center point of the object is located at a focal point of the spherical mirror, anda longitudinal optical axis passes through the aperture stop, the spherical mirror and the object, andillumination of the object generates the target image, which is then reflected from the spherical mirror toward the aperture stop, for testing the sensing apparatus.

Abstract
A generator and projector system for providing a test target for testing sensing apparatus includes an aperture stop located adjacent to the sensing apparatus. Also included are a spherical mirror having a concave side facing the aperture stop and an object disposed between the spherical mirror and the aperture stop. The object includes various test targets for testing the sensing apparatus. A longitudinal optical axis passes through the aperture stop, the spherical mirror and the object. Illumination of the object generates the test target, which is then reflected from the spherical mirror toward the aperture stop, for testing the sensing apparatus.

9. A test set for testing multiple sensing devices, in which the sensing devices include multiple entrance pupils arranged across a large area for viewing a target image,
the test set comprising: -
a housing including an aperture stop, a spherical mirror and an object, the aperture stop having a diameter sufficiently large to view the multiple entrance pupils, and the aperture stop arranged to face and surround the entrance pupils, the spherical mirror having a concave side facing the aperture stop, the object disposed between the spherical mirror and the aperture stop, wherein a longitudinal optical axis passes through the aperture stop, the spherical mirror and the object, and an illumination device for illuminating the object, wherein illumination of the object generates the target image, which is then reflected from the spherical mirror toward the aperture stop, and collimated for viewing by the sensing devices. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. An image projector comprising:
-
a housing including; a spherical mirror, an aperture stop; and a focal area for the spherical mirror, the focal area located between the aperture stop and the spherical mirror, wherein the focal area includes a plate having multiple perforations for allowing the light to reflect toward the aperture stop; and a light for illuminating the focal area, wherein when the light illuminates the focal area, the spherical mirror is configured to reflect the focal area toward the aperture stop. - View Dependent Claims (17, 18, 19, 20)
