Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing holographic projector systems face inefficiencies in providing a high-speed stream of pixel position values for spatial light modulators, leading to potential bottlenecks in operation and reduced performance in applications like head-up displays.
Innovation Solution
A logic circuit utilizing a single unity addition module combined with multiple pipeline modules is used to generate a high-speed stream of pixel position values, effectively scaling up the operational rate by the number of pipeline modules, which are assigned unique sequential identity values to produce a sequential stream of multi-bit binary outputs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single unity addition module is used to generate pixel position values, then device complexity is reduced, but the operational speed is insufficient to meet the demands of spatial light modulators
Solution Approach 1:
The pixel position value generation process is segmented into multiple pipeline modules (first pipeline module, second pipeline module, etc.), each handling a portion of the sequential values. This allows parallel processing of different segments while using a single unity addition module, thereby maintaining low device complexity while improving generation speed to meet spatial light modulator demands.
2Productivity
If multiple pipeline modules are added to increase operational rate, then pixel position value generation speed is improved, but device complexity increases
Solution Approach 1:
Multiple pipeline modules are designed with identical structural configurations, each capable of performing the same function of generating and outputting sequential pixel position values. This modular universal design allows the system to increase operational rate by adding replicated functional units rather than designing complex unique components, thereby improving productivity while controlling device complexity through standardization.
3Stability of the object's composition
If pipeline modules are assigned unique sequential identity values, then the sequential stream of pixel position values is ensured, but the complexity of managing multiple pipelines increases
Solution Approach 1:
Each pipeline module is pre-assigned a unique sequential identity value (first pipeline identity value, second pipeline identity value, etc.) during system configuration. This preliminary assignment of identities ensures that when multiple pipeline modules operate in parallel, they naturally output pixel position values in the correct sequential order without requiring complex real-time control logic to manage the sequencing, thereby maintaining value composition stability while minimizing control complexity.

AI summary
A logic circuit that can output a stream of sequential values, representing pixel position values, for a pixelated display device such as a spatial light modulator. The logic circuit may comprise an advanced integrated circuit such as a field-programmable gate array (FPGA) or an application-specific integrated circuit (ASIC). The stream of sequential values that is output by the logic circuit can be used by another logic circuit to calculate corresponding values of a software function, for populating those pixels of the pixelated display device. The software function can be, for example, a lens function or a grating function, which might be combined with a hologram, such as a computer-generated hologram (CGH), for display on the pixelated display device.
