<p>Throughput between two objects (12, 13) of light or another physical quantity (14) having a substantially unimodal throughput profile in terms of relative orientation of said objects, is maximized. To this end, the physical quantity is initially transmitted between the objects at other than optimum throughput in the substantially unimodal throughput profile, and relative movement in loops (16, 41) in the substantially unimodal throughput profile is imposed on the objects. Throughput intensities are detected at different specific points (31-39) along the loops, and detected throughput intensities are arranged at corresponding different specific points in an array, from which the relative orientation of the objects at which a maximum throughput (Imax) has occurred is identified. A discrepancy may be displayed (128) or the objects are moved unto that optimum relative orientation. The process may be reiterated until maximum throughput (Imax)max has been achieved, at least within an acceptable tolerance.</p> |
