1. Apparatus for use with a system which includes a detector array operable to produce a first signal containing information indicative of the characteristics of a remote object and to produce a second signal containing information indicative of the range to the remote object comprising:
- radiation emitting means operable in a first condition to transmit radiation to the remote object so as to substantially uniformly illuminate the remote object, the remote object reflecting at least a portion of the radiation to the detector array for use thereby in producing the first signal and in a second condition to transmit radiation to the remote object so as to provide a non-uniform pattern of illumination on the remote object, the remote object reflecting at least a portion of the radiation to the detector array for use thereby in producing a second signal.

Abstract
Apparatus for illuminating a remote object first with uniform intensity and second with a pattern so the detector array may view the object to determine its characteristics and view the pattern to determine the range to the object.

9. Apparatus for use with character recognition and range finding equipment which comprises an array of radiation sensitive detectors positioned to receive radiation along a first path from a remote object and operable to produce a first output containing information relative to the character of the remote object and a second output containing information relative to the range to the remote object comprising:
-
radiation emitting means having first and second conditions, in the first condition said emitting means transmits radiation to the remote object so that the radiation from the remote object to the detector array may be used to produce the first output and, in the second condition, said emitting means transmits radiation so as to illuminate the remote object in a non-uniform pattern so that the radiation from the remote object to the detector array may be used to produce the second output; and control means connected to said emitting means and operable to change said emitting means from the first condition to the second condition. - View Dependent Claims (10, 11, 12, 13, 14, 15)
