Using two line scanning based spectral cameras simultaneously in one measurement process to create wider spectral area from the measured target

In this paper, we describe one method how we can combine two different line scanning based spectral cameras, visible and infrared, to one measurement process and how we can automatically combine their different spectral areas to one wide area from 400 nm to 1700 nm. Proposed method has been used in scientific projects and we present two practical applications where this system is used and what benefits we get from it. Main part of this study is that how we can make more effective measurement process by using two line scanning based spectral cameras at the same measurement process and how we can combine those spectral cameras' spectra. We also describe differences between common spectral imaging systems. We also represent one of our produced software algorithm which we can use in measurement process.
