ABSTRACT:
A display analyzer analyzes an image from a unit (10) under test. The analyzer has a carriage (18, 20) for adjustably supporting a detection device (16). The carriage has at least two degrees of freedom. The detection device has a given field of view and can produce a viewing signal responsive to the image size and brightness within the field of view. This viewing signal is produced with a predetermined characteristic in response to the appearance of a given image at the center of said field of view. The display analyzer also has an analyzing device (50) for producing a carriage adjustment signal. The carriage is operable to move in response to this adjustment signal. The analyzing device is operable to produce information in response to the production of the viewing signal.
