摘要： A method of focusing a telecentric imaging system (30), particularly as a part of a measuring machine (10) includes measuring an image of a feature (25) of an object (24) through the telecentric imaging system (30) in a telecentric operating mode and measuring an image of the feature (25) of the object (24) through the telecentric imaging system (30) in a non- telecentric operating mode. A value is acquired characterizing a function by which the size of the imaged feature varies in the non-telecentric mode with the relative displacement of the object (24) through the depth of field (D). The measures of the image of the feature (25) of the object (24) in the telecentric and non-telecentric modes are related to each other and to the acquired value as an estimate of a relative displacement of the object (24) from the best focus position.

摘要： A video measurement system includes an imaging system, a reticle projector for projecting an image of a reticle through the imaging system onto the test object, and a camera for capturing images of the test object together with the reticle image projected onto the test object through the imaging system. A selective reflector reflects the reticle image into the camera from a position along the imaging system in advance of the test object. A mode selector is operable in a first mode for directing the reticle image to the test object and from the test object to the camera and is operable in a second mode for directing the reticle image to the selective reflector and from the selective reflector to the camera.

摘要： An optical inspection system for capturing images of backlit test objects at two or more aperture settings includes a telecentric imaging system having a first setting associated with a first size aperture stop and a second setting associated with a second larger size aperture stop. An illumination system includes a substage illuminator incorporating (a) a first set of one or more light sources surrounded by a first barrier that defines a first size aperture stop and (b) a second set of one or more light sources located beyond the first barrier and surrounded by a second barrier that defines a second larger size aperture stop. The respective first and second size aperture stops of the illumination system image to the respective first and second size aperture stops of the telecentric imaging system at the respective first and second settings.
