2 Introduction
• Use the camera’s XML correction file and select the rejection filters used to apply spectral
correction correctly. Each set of rejection filters have an associated correction matrix that
is used to compute the corrected ‘virtual bands’.
• Get a dark reference at the images exposure time: the dark reference image is an image
captured with the lens closed and that only contains bias noise.
• Get a white reference image: an image of a white uniform surface that reflects the light
uniformly and it is used to maximize the dynamic range of the camera and characterize
the system.
To help the user in the correction process of raw hyperspectral images, Photonfo-
cus have developed an SDK for the Hyperspectral cameras. There is a document
[HSI_WIZARD], which guides users through the complete correction process. Also
the document [HSI_HOW_TO_GET_STARTED] helps to get started.
