title = "Development and design of a line imaging spectrometer sampler (LISS) - A user manual",
abstract = "The objective of this report is to develop and describe the software for a Line Imaging Spectrometer Sampler (LISS) to perform measurements of spectra combined with a digital RGB photo of a measurant. Secondly this report should enable users to performmeasurements with the system. The measuring devices consist of 2 16-bit cooled SBIG ST-6 CCD cameras each equipped with an Imspector imaging spectrograph for measuring reflectance in the visual and the near infrared range, respectively, a digital cameraand a differential global positioning device (dGPS). The controlling and data collecting tasks are developed as a Graphical User Interfaced (GUI) hosted by Matlab Release 12 from Mathworks. This GUI enables the operator to perform measurements from alldevices simultaneously together with notes specific for the measurant and store all the data in one Matlab data structure. The software includes dynamic exposure of the two CCD cameras ensuring optimal use of 16 bit range under unstable illuminationconditions. A routine, handling dark frame subtraction in a robust manner minimising the effect of hot pixels is also included. This report enables a novice user to perform measurements with LISS relatively easy, enabling the user to put the main focusat the analytical phase and not on the measuring phase.",
