研究目的
To develop a multi spectral imaging system utilizing a linear response CIS with over 10Me– FWC, which is equivalent to 70dB SNR, and high QE from UV to NIR, and an electrically tunable multi bandpass optical filter with narrow and stable FWHM, fast waveband switching capability which is to be synchronized with the CIS operation and no resolution degradation.
研究成果
The developed spectral imaging system has measurement accuracy of less than 5mg/dl glucose concentration due to the 70dB SNR imaging at 960nm and 1050nm. The system is highly adoptive to not only conventional but also new spectral imaging applications.
研究不足
The system's measurement accuracy is determined by the detection accuracy of microscopic change of light intensity under strong light irradiation, where the SNR is given by the equation (2).
1：Experimental Design and Method Selection:
The methodology involves the development of a CMOS image sensor with high SNR and wide spectral response, and an electrically tunable multi bandpass optical filter.
