Solution Overview
Problem
Current imaging systems, particularly those for holographic displays, face limitations in miniaturization, intensity, resolution, and color due to reliance on electrically addressed inputs, and existing optically addressed systems incorporate electrical components that restrict scale and quality.
Innovation Solution
An exclusively optically addressed projection system using an electro-optical device to generate write beams with different phase values, interacting with a plasma or solid-state device to produce holographic images, where information is inputted and outputted entirely optically, without electrical components, allowing for independent control of write beams and coherent read beams to generate holographic images with multiple colors.

Engineering Contradiction Analysis
1Length of moving object
If electrically addressed inputs are used in imaging systems, then practical limitations relative to scale are realized, but miniaturization of imaging systems is restricted
Solution Approach 1:
The patent replaces electrically addressed inputs with optically addressed inputs. The spatial light modulator is controlled by optical fields rather than electrical signals, eliminating the need for electrical connections and components at the modulator level. This substitution enables miniaturization by removing electrical infrastructure while maintaining spatial light modulation capability through all-optical control mechanisms.
Solution Approach 2:
The patent extracts and removes electrical components from the imaging system by implementing exclusive optical addressing. The spatial light modulator operates without electrical inputs, extracting the electrical control layer and replacing it with optical control. This extraction eliminates the scale limitations imposed by electrical components while preserving the essential light modulation function.
2Manufacturing precision
If optically addressed systems with electrical components are used, then imaging functionality is achieved, but scale and quality restrictions are imposed
Solution Approach 1:
The patent substitutes electrical control mechanisms with optical control mechanisms. The spatial light modulator is addressed exclusively by optical fields, replacing electrical addressing with optical field modulation. This substitution improves image quality by eliminating electrical interference and component limitations while maintaining precise spatial control through optical means.
Solution Approach 2:
The optically addressed spatial light modulator operates autonomously using only optical inputs. The device self-modulates light based on optical addressing patterns without requiring electrical intermediaries. This self-service operation eliminates electrical component dependencies, improving both image quality and system scalability.
3Adaptability or versatility
If electrical components are incorporated in optically addressed systems, then addressing functionality is provided, but restrictions on overall imaging system scale and quality are placed
Solution Approach 1:
The patent extracts electrical components from the addressing system, implementing exclusive optical addressing. The spatial light modulator receives only optical inputs, with electrical components completely removed from the addressing pathway. This extraction enables unrestricted system scaling while maintaining high-quality imaging performance.
Solution Approach 2:
The optically addressed spatial light modulator serves multiple functions through a single optical input interface. It performs spatial modulation, phase control, and amplitude control exclusively through optical means, eliminating the need for separate electrical control systems. This universality improves scalability by providing a unified optical interface that can be scaled without electrical infrastructure constraints.
