Solution Overview
Problem
Existing light measuring devices struggle to efficiently measure lights from different optical paths simultaneously, making it difficult to accurately detect and analyze lights from multiple remote or separated sources in a single location.
Innovation Solution
A light measuring device comprising a spectroscope, multiple light guiding units, and a light receiving unit that allows lights from different sources to be directed and received separately, enabling measurement of multiple lights in one place without the need for individual adjustments of multiple spectroscopes, and incorporating a control unit for wavelength selection and data acquisition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple spectroscopes are used to measure lights from different optical paths simultaneously, then measurement capability is improved, but device size increases and individual difference adjustment becomes necessary
Solution Approach 1:
The patent combines multiple light paths into a single spectroscope by using separate light guiding units (optical fibers) for each path. Multiple lights from different sources are guided through individual optical fibers to a common spectroscope, allowing simultaneous measurement of multiple lights while using only one spectroscope, thus avoiding the need for individual difference adjustment and reducing device size.
Solution Approach 2:
The patent segments the light gathering function from the spectral analysis function. Light guiding units (optical fibers) are separated for each light source to collect lights from different locations independently, while the spectroscope remains unified for spectral analysis. This segmentation allows independent optimization of light collection paths while sharing the spectral analysis resource.
2Adaptability or versatility
If multiple spectroscopes are used to measure lights from different optical paths simultaneously, then measurement capability is improved, but adjustment complexity increases due to individual differences
Solution Approach 1:
The patent merges the spectral analysis function into a single spectroscope that receives lights from multiple sources through separate light guiding units. By using one common spectroscope instead of multiple spectroscopes, the system eliminates individual difference adjustments and calibration complexities associated with multiple independent spectral analysis devices.
3Device complexity
If a single spectroscope is used to measure multiple lights, then device size is reduced, but it becomes difficult to separately receive lights from different positions
Solution Approach 1:
The patent segments the light collection function into separate light guiding units (optical fibers) for each light source location. Each light guiding unit independently collects light from its specific position and guides it to the single spectroscope. This segmentation maintains the ability to separately receive and identify lights from different positions while using only one spectroscope for spectral analysis.
Solution Approach 2:
The patent introduces light guiding units (optical fibers) as intermediary elements between the light sources and the spectroscope. These intermediaries carry light signals from different positions to the single spectroscope, preserving the spatial information and enabling separate reception of lights from different locations without requiring multiple spectroscopes.

AI summary
A light measuring device can measure, in one place, a plurality of lights guided from different places. The light measuring device includes a spectroscope configured to selectively transmit light having a desired wavelength, a plurality of light guiding units configured to guide measurement target light to the spectroscope, and a light receiving unit configured to receive the light emitted from the spectroscope. The light guiding units are provided in positions where different lights are respectively made incident on incident ends of the light guiding units as the measurement target light and positions where emission ends of the light guiding units respectively emit lights to different positions of the spectroscope. The spectroscope emits the lights, which are made incident from the light guiding units, respectively from different positions. The light receiving unit separately receives the lights emitted from the different positions of the spectroscope.
