Problems solved by technology

However, due to small misalignments in the optics that occur during the manufacture and processing of the light modulator, there are displacement differences between the gratings that make up the one-dimensional array, resulting in a horizontal dislocation when the image is projected vertically onto the display.

Embodiment Construction

[0030] Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like numerals refer to like parts throughout. The embodiments are described below in order to explain the present invention by referring to the figures.

[0031] Fig. 1 shows a display device / system using a light modulator according to an embodiment of the present invention.

[0032] Referring to FIG. 1 , as an example, a display system may include a laser diode 110 , a light modulator 120 and a light scanner 130 .

[0033] The laser diode 110 is a widely used device in the fields of optical communication, optical storage, and optical information processing. The laser diode 110 includes a p-n junction, and excites a region adjacent to the p-n junction, thereby generating a laser beam. Then, the laser beam generated by the laser diode 110 may be input to the light modulator 120 to perform modulation by applying an input v...

Abstract

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.

Description

[0001] This application claims priority from Korean Patent Application No. 10-2006-0051589 filed with the Korean Intellectual Property Office on Jun. 8, 2006, which is hereby incorporated by reference in its entirety. technical field [0002] One or more embodiments of the present invention relate to techniques for compensating displacement differences in optical modulators, and more particularly, the present invention relates to a method for generating and / or implementing a line profile ( line profile) methods, media and systems. Background technique [0003] In general, optical signal processing has the advantages of high-speed processing, parallel processing, and massive information processing, making it different from existing digital processing that cannot handle large amounts of data or perform real-time data processing. Conduct research into the design and fabrication of binary phase filters, optical logic gates, optical amplifiers, image processing techniques, optica...
