Abstract:
1. A method for detecting, and determining the direction of, an incident beam of light; said method comprising the steps of: receiving the incident beam of light on a multiple-sector-cell detector; operating the multiple-sector-cell detector to determine that a first sector of the multiple sectors has received the incident beam of light; first deflecting the incident beam of light by a first measured amount, along the multiple-sector-cell detector, to reach a boundary between the first sector and another sector of the multiple sectors; wherein the first deflecting the incident beam of light is performed along a track that is generally normal to the boundary between the first sector and the another sector of the multiple sectors; and second deflecting the incident beam of light by a second measured amount, along the boundary, to reach a central position of the multiple-sector-cell detector.
