Abstract
A system for displaying information concerning position of a light beam comprises a detector generating a first signal indicating position of the beam along a first dimension, and a second signal indicating position of the beam along a second dimension. A crossed dot bar graph display is coupled to receive the first and second signals. The crossed dot bar graph display includes a first linear array of indicators (LEDs) for indicating position along the first dimension, and a second linear array of indicators for indicating position along the second dimension. The first and second linear arrays intersect at a center indicator. One dot is displayed in the first array showing deviation in the first dimension. One dot is displayed in the second display showing deviation in the second dimension. When both dimensions are aligned to the center indicator, only the center indicator is activated. The system can be expanded to any number of dimensions.
