Claim:
1. A system for non-destructive evaluation of water ingress in photovoltaic modules, comprising: a light source; a moving mirror positioned in a beam path of the light source; a focusing lens positioned in the beam path of the light source and between the light source and the moving mirror; a beam splitter positioned in the beam path of the light source between the light source and the moving mirror; a stationary mirror positioned adjacent the beam splitter and outside the beam path of the light source; an objective lens positioned between the beam splitter and the photovoltaic module, the objective lens being outside the beam path of the light source; and an imaging module configured to capture two-dimensional spectral image data relating to a water content of a photovoltaic module positioned opposite the stationary mirror and outside the beam path of the light source.
