Abstract
Abstract THE INVENTION CONTEMPLATES COORDINATED OPTICAL AND ECHO-RANGING RANGE FINDERS ON THE SAME DIRECTIONAL ALIGNMENT WHEREBY ECHO-RANGE DATA MAY BE AVAILABLE TO IMPROVE THE RANGE SETTING OF THE OPTICAL RANGE FINDER, FOR HIGH-QUALITY RANGING IN THE PRESENCE OF MASKING OBJECTS. CONVERSELY, THE IMPROVED RESOLUTION ACHEIVED BY VISUAL RANGING CAN BE UTILIZED TO UPGRADE THE SELECTION OF THE PARTICULAR ECHO (AMONG A SPREAD OF MASKING ECHOES) FOR WHICH A RANGE DETERMINATION IS TO BE MEASURED BY THE ECHO-RANGING FINDER. VARIOUS SPECIFIC COORDINATING RELATIONSHIPS ARE DESCRIBED FOR THE TWO RANGE FINDERS.
