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