Solution Overview
Problem
Conventional goniophotometers require multiple single-point scans to detect the spatial spectrum and optical field distribution of light sources or optical elements, making the process time-consuming.
Innovation Solution
A detecting system comprising a light spatial distribution unit, a chromatic-dispersion light-splitting unit, and a detecting unit, which forms and splits light into point sources and generates optical field distributions in a single detection step, replacing the need for multi-time single-point detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a conventional goniophotometer is used to detect the spatial spectrum and optical field distribution, then the detection can be performed with a single-point scanning method, but the detection process takes a long time
Solution Approach 1:
The light field from the under-test object is segmented into multiple point light sources by the light spatial distribution unit (screen with holes). This allows parallel detection of multiple spatial points simultaneously, converting a sequential single-point scanning process into a parallel multi-point detection process, thereby significantly reducing detection time while maintaining measurement precision
Solution Approach 2:
The invention transitions from one-dimensional single-point scanning to two-dimensional parallel detection by using a screen with multiple holes to create an array of point light sources. This dimensional expansion allows simultaneous capture of spatial spectrum and optical field distribution across multiple points, resolving the time-consuming nature of sequential scanning
2Measurement precision
If multiple single-point scans are performed to obtain complete optical field distribution data, then comprehensive detection results are achieved, but the detection process becomes complex and time-consuming
Solution Approach 1:
The invention merges multiple single-point detection operations into a single parallel detection process. The light spatial distribution unit combines multiple light paths into separate point sources, while the chromatic-dispersion light-splitting unit combines spectrum separation with spatial detection, allowing comprehensive optical field distribution to be obtained in one operation rather than through multiple sequential scans
Solution Approach 2:
The detecting unit serves multiple functions simultaneously: it detects both the spatial distribution and spectral characteristics of the light field in parallel. The integrated system performs what would traditionally require multiple specialized measurements, reducing process complexity while maintaining comprehensive detection capability
