摘要：
An apparatus comprising: a direct push probe configured to be pushed into a subsurface soil environment; a transparent window mounted to a side of the probe; a white light source mounted within the probe and positioned such that when the white light source is activated only white light exits the window; an ultraviolet (UV) light source mounted within the probe and positioned such that when the UV light source is activated only UV light having a given wavelength exits the window; and an imaging system disposed within the probe and configured to capture a white-light-only-illuminated image and a UV-light-induced-fluorescence image of the subsurface soil environment at a given depth, wherein the imaging system comprises a longpass filter to filter out the UV light having the given wavelength.
