To integrate a hyperspectral system you'll need to carefully select the proper components to assure that the performance of each subsystem is not compromised by that of other subsystems, write the drivers to integrate these components, develop special algorithmic tools to analyze and visualize these data, and finally integrate the entire system into a smoothly functioning instrument. Most organizations may take from three months to a year to go through this process, and there is no assurance of success.
OKSI's system includes everything required for a plug-N-play instrument. Moreover, your system can be customized to the specific requirements of your project, operating environment, and budget. From the laboratory to the field, using wall power or battery, optimized spectral resolution to match spatial resolution, spatial coverage vs. spatial resolution, etc.
These systems are built using the best Liquid Crystal Tunable Filters (LCTF) made by Cambridge Research & Instrumentation, CRI, we use the most appropriate digital cameras for the job, optimized apochromatic optics, state-of-the-art frame grabbers, and properly configured host computers. Moreover, the also includes ENVI, the best available hyperspectral analysis software package from RSI. And on top, we incorporate the Hyperspectral Toolkit developed at OKSI.
But that's not all. The entire hyperspectral system functions from within ENVI environment. Image cubes are saved as ENVI files with the proper header so that data are acquired and analyzed with no need to switch between applications. Using the tools provided , data can be converted from radiance to reflectance, statistical spectral properties can easily be obtained, and results compared with library spectra or used to build new spectra.
