Photometer Luminous Flux Splitter for Parallel Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional photometry and data acquisition for light emission profile analysis are performed sequentially, resulting in poor efficiency as they cannot be performed in parallel.
Innovation Solution
A photometer is designed with a luminous flux splitting mechanism that directs light to both a finder optical system and a photometric means, allowing a light receiving sensor to generate outputs for light emission profile analysis independently of photometry, using components like half mirrors, shutters, and light guide mirrors to manage light paths and prevent reverse incident light interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If photometry and data acquisition for light emission profile analysis are performed sequentially using a single light receiving sensor, then the device complexity is reduced, but the productivity is poor because they cannot be performed in parallel
Solution Approach 1:
The patent divides the light receiving function into two separate sensors: a first light receiving sensor dedicated to photometry and a second light receiving sensor dedicated to data acquisition for light emission profile analysis. This segmentation allows both functions to operate simultaneously and independently, resolving the contradiction between productivity improvement and device complexity by organizing the system into specialized modular components.
Solution Approach 2:
The patent employs a single objective lens that serves multiple purposes: it collects light for both photometry measurements and light emission profile analysis. This multi-functional design allows the system to perform diverse measurements without proportionally increasing the number of optical components, thereby improving productivity while controlling device complexity.
2Measurement precision
If a single light receiving sensor is used for both photometry and data acquisition, then the device complexity is minimized, but the measurement precision is compromised because the sensor cannot simultaneously capture both types of data
Solution Approach 1:
The patent assigns dedicated light receiving sensors to specific measurement tasks: the first sensor is optimized for photometry while the second sensor is optimized for light emission profile analysis. This functional segmentation ensures that each sensor can operate at its optimal performance level for its designated task, thereby achieving high measurement precision for both types of data without requiring a single complex multi-functional sensor.
Solution Approach 2:
Each light receiving sensor is positioned and configured with specific optical characteristics suited to its measurement purpose. The first sensor receives light through optical path A optimized for photometry, while the second sensor receives light through optical path B optimized for light emission profile analysis. This local optimization of sensor properties and positions enables high precision measurements tailored to each function.
