Abstract :
A new-styled molecular hyperspectral imaging system (MHIS) based on acousto-optic tunable filter (AOTF) was introduced in this paper. This system consists of a Charge-coupled Device (CCD) camera, microscopy, AOTF, and a RF driver. Real-time images are obtained both at multiple, continuous wavelengths and at relatively narrow spectral bandwidths to generate a 3D data including one spectral and two spatial dimensions. AOFT cell covers the spectral band from 550nm to 1000nm with a spectral resolution range of 2nm-6nm. This work presents principle and structure of MHIS as well as its characteristics. The analysis results show that MHIS is promising in biomedical and early diagnosis.
