Solution Approach 1:

The system transitions from traditional single-wavelength detection to multi-wavelength spectral detection by adding a wavelength dimension. Multiple sensors detect fluorescence across different wavelength regions simultaneously, creating a spectral profile that preserves both the intensity information needed for precision measurement and the wavelength distribution information needed for spectrum analysis. This dimensional expansion allows simultaneous achievement of measurement precision and spectrum information retention.
