Optoelectronic Arrangement for Visible Alignment of Non-Visible Light
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aligning non-visible light emitted by sensor arrangements with objects to be investigated is challenging due to the difficulty in visualizing the emitted light.
Innovation Solution
An optoelectronic arrangement comprising an optoelectronic semiconductor chip, a wavelength-converting element, and a detector component, where the semiconductor chip emits light with a first peak wavelength in the visible spectral range and the wavelength-converting element converts it to light with a second peak wavelength in the non-visible spectral range, allowing for easy alignment and detection of light backscattered from the target area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If non-visible light is used for sensing, then measurement capabilities are improved, but alignment with objects becomes difficult
Solution Approach 1:
The patent employs a wavelength-converting element that converts non-visible light (e.g., UV) to visible light, enabling operators to see the alignment path. This color/wavelength transformation allows the invisible sensing beam to become visible for easy alignment while maintaining the original non-visible wavelength for measurement purposes
Solution Approach 2:
The wavelength-converting element acts as an intermediary between the non-visible light source and the human eye. It receives non-visible light and transforms it into visible light, serving as a mediator that enables visualization without altering the fundamental sensing mechanism
2Ease of operation
If multiple light sources are used for visible and non-visible light, then alignment and detection are improved, but device complexity increases
Solution Approach 1:
The patent combines a visible light source and a non-visible light source into a single integrated unit. Both light sources are housed together with their respective detectors, creating a unified sensor arrangement that provides alignment and detection functions without requiring separate devices
Solution Approach 2:
The integrated sensor arrangement performs multiple functions: the non-visible light source provides measurement capability while the visible light source provides alignment guidance. Both sources share the same housing and detection system, making the device universal for both alignment and sensing operations
