Modeling a Sensor to Improve Its Efficacy

Figure 4

Four additional symmetry-breaking albedo patterns were employed. In all cases, the sensor was placed in the orientation at the center of the pattern, indicated by . In the two lower patterns, the center of the white square was shifted diagonally from the center by 4 mm as indicated by the coordinates (white text) of the corner. The recorded intensity levels are displayed in the white albedo area.
