Active Hyperspectral Imaging Technology Based On Tunable Wavelength

Nowadays, hyperspectral imaging technology has been widely used andachieved a lot in remote sensing or detection area. However, when it comes to someemerging disciplines like medicine, material science and microelectronics, thetraditional passive imaging type does not go will with some applications. In thisresearch, we induced a wavelength tunable active system, using monochromatic lightto realize a rapid spectral measurement. This novel system will not be influenced bythe environmental factors such as the weather or the sunshine. With these advantages,it can be widely applied in many fields. The research results can be a good referencefor similar systems.In this paper, we made a deep and comprehensive research on activehyperspectral imager technology based on tunable wavelength and acquired severalachievements below:(1) Acquired active hyperspectral images based on tunable wavelength.Different from the traditional passive imaging type, this system used an activeimaging technology based on a grating spectrometer and could obtain thehyperspectral image of target object with all kinds of environmental light conditions.(2) Accomplished the development of hardware and software. Compiled afriendly system platform with flexible parameters.(3) Dispose of the acquired images including adjustment, enhancement,coloring and transaction of raw data to make a readable result.
