Solution Overview
Problem
Current methods for analyzing multiple biological samples using light detection systems are limited in their ability to efficiently obtain detailed spectral information from two-dimensional arrays of samples, leading to challenges in resolving spectral components and reducing crosstalk between adjacent spectra.
Innovation Solution
The development of a spectral imaging system that includes a two-dimensional array of examination sites, an illumination system, an optical system with dispersion elements, and a light detector, which disperses emitted light into spectra and filters them to reduce crosstalk, allowing for concurrent imaging of spectra from multiple samples with improved resolution and reduced mechanical complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional light detection systems are used to analyze multiple biological samples, then sample analysis can be performed, but spectral resolution is insufficient and crosstalk between adjacent spectra cannot be reduced
Solution Approach 1:
The detection system is segmented into multiple independent detectors arranged in a two-dimensional array, where each detector corresponds to a specific spatial position and spectral wavelength range. This segmentation allows simultaneous detection of multiple samples with high spectral resolution while minimizing crosstalk between adjacent spectra through spatial separation.
Solution Approach 2:
The system transitions from traditional one-dimensional spectral detection to two-dimensional spectral imaging by adding a spatial dimension to the detection array. This dimensional expansion enables concurrent acquisition of spectral information from multiple sample positions, improving both spectral resolution and throughput without proportionally increasing system complexity.
2Measurement precision
If sequential analysis methods are used for multiple samples, then detailed spectral information can be obtained, but data acquisition time is excessive
Solution Approach 1:
The system enables continuous concurrent detection of spectral information from all samples in the array simultaneously, rather than sequentially analyzing each sample. This continuous parallel action maintains high spectral information quality while dramatically reducing total data acquisition time, as all samples are analyzed at the same time across the two-dimensional detector array.
3Measurement precision
If mechanical scanning systems are used to capture spectra from sample arrays, then spectral data can be collected, but mechanical complexity increases and kinetic assay speed decreases
Solution Approach 1:
The system replaces mechanical scanning components with a stationary two-dimensional detector array that simultaneously captures spectral information from all sample positions. This substitution eliminates complex mechanical moving parts while maintaining high spectral data quality, and enables rapid kinetic assays by removing mechanical scanning bottlenecks.
