Optical Time Sequence Cache for Dynamic Scene Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current optical computing methods are limited in processing ultrafast dynamic optical fields due to reliance on digital memory for read/write operations, which hinder real-time analysis and feedback control, and lack a technology to effectively bridge the dimension mismatch between spatial and temporal optical fields.
Innovation Solution
The method involves acquiring a time frame input from a dynamic scene, performing spatial modulation to obtain space information, and mapping it to an optical time sequence using space division multiplexing (SMUX) and wavelength division multiplexing (WMUX) technologies, creating an optical time sequence cache that bridges the parallel space and time dimensions, enabling spatiotemporal feature space processing.

Engineering Contradiction Analysis
1Speed
If digital memory read/write operations are used for optical computing, then data can be stored and retrieved, but processing speed is severely limited and real-time analysis is hindered
Solution Approach 1:
The patent extracts and eliminates the digital memory read/write operations from the optical computing system. By directly processing optical fields without intermediate digital memory storage and retrieval steps, the system removes the time-consuming memory access bottleneck, enabling real-time optical field processing at ultra-high speeds.
Solution Approach 2:
The patent replaces the mechanical/electronic memory read/write process with direct optical field processing. Instead of converting optical data to digital format, storing in memory, and reading back, the system processes optical fields directly in the optical domain, substituting a faster physical process for the slower digital memory cycle.
2Adaptability or versatility
If spatial modulation only is used, then the system is simple, but it cannot effectively process dynamic optical fields requiring both space and time dimensions
Solution Approach 1:
The patent extends the processing from purely spatial modulation to spatiotemporal modulation by adding the time dimension. The system now modulates optical fields in both space (across the optical field profile) and time (across multiple time frames), enabling processing of dynamic scenes while maintaining a relatively simple integrated device structure.
Solution Approach 2:
The patent creates a multi-functional device that can simultaneously perform spatial encoding, temporal encoding, and optical field processing. The same device structure handles both spatial and temporal dimensions of the optical field, making the system versatile for various dynamic optical computing tasks without requiring separate specialized components.
3Adaptability or versatility
If frequent memory access is performed to process dynamic optical fields, then multiple frames can be processed, but the processing speed is severely limited
Solution Approach 1:
The patent enables continuous processing of dynamic optical fields by eliminating the interruptive memory access cycles. The system processes optical fields continuously in the optical domain, maintaining uninterrupted processing flow across multiple time frames, which dramatically increases visual computing productivity compared to the stop-and-go nature of memory-based processing.
