Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In space optical communication, existing systems face challenges in efficiently transmitting spatial optical signals over a wide range due to the need for labor-intensive adjustments to achieve a 360-degree communication angle, and existing omnidirectional transmission techniques suffer from signal intensity degradation.
Innovation Solution
A transmitter design incorporating a light source with multiple emitters, a phase modulation-type spatial optical modulator with set modulation regions, and a reflector with a curved reflective surface that directs modulated light in a specific horizontal plane, allowing for stable and continuous signal transmission to communication targets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If omnidirectional transmission is performed to detect communication targets, then the communication angle can be covered, but the signal intensity decreases making continuous communication difficult
Solution Approach 1:
The transmitter divides the 360-degree horizontal transmission range into multiple directional beams using a light source with multiple emitters and a spatial optical modulator. Each emitter corresponds to a specific modulation region, creating separate optical beams for different communication targets. This segmentation allows each beam to maintain high intensity while collectively covering the full omnidirectional range.
Solution Approach 2:
The patent transitions from traditional omnidirectional point-source transmission to a multi-dimensional beam arrangement. By using multiple emitters positioned at different locations and controlling them with a spatial optical modulator, the system creates multiple discrete optical beams in the horizontal plane, effectively adding a spatial dimensionality to the transmission approach.
2Adaptability or versatility
If adjustment mechanisms are added to achieve 360-degree communication angle, then the transmission range is extended, but the device complexity and installation labor increase
Solution Approach 1:
The transmitter achieves omnidirectional coverage through its inherent multi-emitter structure and spatial optical modulator control, without requiring external adjustment mechanisms. The system self-configures the transmission directions by controlling which emitters are activated and their corresponding modulation regions, eliminating the need for manual or automated directional adjustment devices.
Solution Approach 2:
The light source with multiple emitters and the spatial optical modulator serve multiple functions simultaneously: they generate optical signals, control transmission directions, and enable omnidirectional coverage. This multi-functionality consolidates what would traditionally require separate adjustment mechanisms into a single integrated system.
3Illumination intensity
If multiple emitters and modulation regions are used to transmit to specific directions, then the signal intensity is maintained, but the device structure becomes more complex
Solution Approach 1:
The patent combines multiple emitters and a spatial optical modulator into a single integrated light emitting unit. Rather than using separate directional light sources, the system merges multiple emission elements and controls them collectively through the spatial optical modulator, reducing structural complexity while maintaining the ability to transmit high-intensity signals in specific directions.
