摘要： A method, medium, and system generating and/or implementing a line profile to compensate for displacement differences in an optical modulator. In the method, a test chart made up of a predetermined number of patches that are arranged at regular gray scale intervals is designed. The designed test chart is displayed using a one-dimensional optical modulator, and the displayed test chart is captured using a camera, thereby acquiring a two-dimensional image. Thereafter, the two-dimensional image is divided into a plurality of regions, and the average value of intensity of light is calculated for each horizontal line of the regions. Finally, a line profile is generated and/or implemented for respective horizontal lines using the calculated average values.
