Solution Overview
Problem
Current methods for characterizing radiation fields, particularly laser radiation, are limited by invasive techniques that alter the radiation field and are unsuitable for high power densities or transient light distributions, and non-invasive methods fail to provide comprehensive characterization of multiple parameters simultaneously.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If invasive methods are used to measure radiation fields, then measurement precision is improved, but the radiation field is altered and measurement reliability deteriorates
Solution Approach 1:
The patent introduces a scattering medium as an intermediary between the radiation field and the detector. The medium scatters the radiation, allowing indirect measurement of the radiation field properties without direct contact. This mediator enables measurement while preserving the original radiation field characteristics, resolving the contradiction between precision and reliability.
Solution Approach 2:
The patent creates a scattered radiation field that copies the spatial and temporal characteristics of the original radiation field. By detecting the scattered radiation distribution, the system reconstructs information about the original field without directly measuring it, thus maintaining field integrity while achieving measurement precision.
2Difficulty of detecting and measuring
If invasive optics are used in high power density radiation fields, then measurement capability is improved, but the optics are destroyed and device reliability deteriorates
Solution Approach 1:
The scattering medium acts as a protective intermediary that allows high power density radiation to be measured without exposing delicate optical components to damaging intensities. The medium distributes and attenuates the radiation, enabling safe detection while maintaining measurement capability.
Solution Approach 2:
The system measures a scattered radiation copy rather than the direct high-intensity beam. This copying approach allows characterization of high power density fields using low-power detectors, eliminating the risk of optical component destruction while preserving measurement capability.
3Reliability
If standard non-invasive methods are used, then radiation field integrity is preserved, but comprehensive characterization of multiple parameters simultaneously is not achieved
Solution Approach 1:
The scattering medium measurement approach serves multiple functions simultaneously: it preserves field integrity, enables 3D spatial characterization, captures temporal dynamics, and provides information about radiation distribution. This multi-functional measurement method achieves comprehensive characterization without compromising field integrity.
Solution Approach 2:
The patent transitions from 2D detector plane measurements to 3D radiation field reconstruction by analyzing the spatial distribution of scattered radiation. This dimensional transformation enables comprehensive characterization of volume radiation fields while maintaining non-invasive measurement integrity.
4Measurement precision
If sequential measurements are performed, then individual properties can be examined, but measurement time increases and productivity deteriorates
Solution Approach 1:
The patent combines multiple measurement objectives into a single simultaneous measurement process. By capturing the scattered radiation field distribution in one measurement event, the system extracts multiple parameters (spatial distribution, intensity, temporal characteristics) concurrently, eliminating sequential measurement delays while maintaining precision.
Solution Approach 2:
The scattering medium continuously provides measurement information during the radiation field interaction. The detector captures ongoing scattered radiation signals, enabling continuous monitoring and simultaneous extraction of multiple parameters without interruption or sequential steps, thereby improving measurement efficiency.
