Abstract
A photoelectric docking device for remotely positioning a first member relative to a second member, having a point light source coupled to the first member, which is directed to focus a narrow beam of light on a photosensor fixedly connected to the second member. The photosensor is responsive to the reception of light from the point light source on the first member to provide electrical outputs representative of the relative position of the point source with respect to the photosensor in three-dimensional space. The electrical outputs of the photosensor are then displaced as a three-dimensional pictorial representation of the relative position of the first and second members. Means are further provided for identifying when the first and second members are in intimate contact.
