Tohoku University/ NIT Sendai College Technology ：High-resolution spectroscopic imaging system：T17-025

・ A compact and highly accurate spectroscopic imaging system　・Visual information can be obtained non-destructively and quickly

Spectroscopic imaging has been applied to analyze and identify substances, but conventional spectroscopic imaging system has problems such as miniaturization of system and high resolution analysis.　 The invention relates to a spectroscopic imaging system combining a highly sensitive image sensor and a high-speed tunable bandpass filter, and has the following features. ・Non-destructive, non-contact, rapid spectroscopic imaging are possible. ・To provide a compact, portable, low-cost spectroscopic imaging system. ・It is possible to obtain a high-resolution spectroscopic video image. ・The transmission wavelength can be controlled by applying a voltage to the liquid crystal. The invention can be applied to component analysis of food production and processing, contamination inspection, growth and yield investigation in agriculture, component analysis in the medical field, etc.
