Abstract
An optical sensing assembly includes a scale, a sensor, and a light source. The scale includes first and second pattern areas. The first pattern area includes first patterns periodically arranged in first and second directions. The second pattern area includes second patterns periodically arranged in the first and second directions. The sensor is configured to move relative to the scale in the first direction and includes first, second, third, and fourth sensing areas. The first and third sensing areas are configured to sense changes of the first pattern area in the first and second directions respectively. The second and fourth sensing areas are configured to sense changes of the second pattern area in the first and second directions respectively. The light source is configured to emit light toward the scale.
