Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing light source modules face challenges in achieving spatial homogeneity of output light due to standing waves caused by single-direction vibration of optical fibers, which affects the quality and distribution of the light emitted.
Innovation Solution
A light source module design that includes a pair of holding members to maintain a linear extension of the optical fiber, with separate vibrators inducing vibrations along two perpendicular directions to suppress standing waves, and additional features like bending or winding of the optical fiber sections to enhance light reflection and distribution, ensuring improved spatial homogeneity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the optical fiber vibrates only along one direction, then the vibration mechanism is simple, but standing wave occurs and spatial homogeneity of output light deteriorates
Solution Approach 1:
The patent applies multi-directional vibration by introducing vibration in both the vertical direction (first direction) and horizontal direction (second direction) perpendicular to the optical fiber axis. This dimensional expansion from single-direction to multi-directional vibration suppresses standing wave formation and improves spatial homogeneity of the output light without requiring overly complex mechanisms.
Solution Approach 2:
The patent employs dynamic vibration control where the optical fiber is subjected to time-varying vibrations in multiple directions. By making the vibration system dynamic rather than static, standing waves are suppressed and the light output achieves better spatial homogeneity while maintaining manageable system complexity through controlled dynamic behavior.
2Manufacturing precision
If the optical fiber is bent or wound to apply stress, then spatial homogeneity of output light is improved, but the optical fiber structure becomes more complex
Solution Approach 1:
The patent applies local quality by introducing stress only in specific portions of the optical fiber (second portion) through bending or winding, while keeping other portions (first portion) linear and unstressed. This localized structural modification improves spatial homogeneity of the output light without requiring the entire optical fiber structure to be complex.

Function Achieved in This Case
The module achieves improved spatial homogeneity of output light, allowing for more efficient and precise light distribution, such as a top hat shape, suitable for applications like resin processing without the need for complex optical systems.
Implementation Method 1
a first vibrator that vibrates the first portion along a first direction intersecting an extending direction of the first portion
Implementation Method 2
a second vibrator that vibrates the first portion along a second direction intersecting the extending direction and differing from the first direction
Implementation Method 3
an optical fiber that guides light output from the light source
Implementation Method 4
the light can be irregularly reflected in the second portion, and the spatial homogeneity of the output light can be further improved
