发明名称 TEST OBJECT USED FOR PROJECTING A SET OF MARKS TO INFINITY
摘要 The collimated test object according to the invention is used for projecting to infinity a set of marks, the positions of which are very accurately known so as to be able to verify the alignment et/or the distortion of optical equipment such as sensors or collimated screens. This test object comprises a plurality of microcollimated sets each comprising a light source, an elementary test object comprising a mark illuminated by said source as well as a collimation lens for projecting said mark to infinity. With this solution, one gets free of aberration problems to which are subject convention test objects of large dimensions.
