Abstract
A laser tracker includes a first optical system located on a structure and that launches a beam from the structure. The laser tracker also includes a locator camera having a second optical system that includes a lens having a center and a clear aperture through which light may pass. The clear aperture has a clear aperture diameter. The second optical system includes a light source that illuminates a retroreflector, receives light reflected back from the retroreflector and forms an image on a photosensitive array that is converted to a digital data set from which the angular direction of the targets can be determined.
