Abstract
A soil imaging probe has a housing with an interior cavity and an outer surface exposed for sliding contact with soil. A window is mounted in the outer surface for providing optical communication between the soil and the interior cavity. An optical module is positioned within the interior cavity. The optical module includes at least one light source and a camera mounted in a block. An indexing surface is defined in the interior cavity to maintain the optical module at a predetermined fixed distance from the window to keep the camera focused on the soil outside the window. An elastomeric fill material fills the interior cavity and substantially surrounds the optical module to reduce energy transference from the housing of the probe to the optical module. An image processing method is also provided to identify pixels in an image captured by the camera that show potential hydrocarbon contamination.
