Abstract: Multi-modality imaging systems and methods for enabling controllable and/or automated switching between different imaging systems or modes. An imaging system includes a base plate having a first exposed region and a second region, a sample stage configured to hold a sample platform, and a first translation mechanism configured to translate the sample stage on the base plate along a first axis between a first position and a second position. In the first position the sample stage is positioned proximal to the first exposed region, and in the second position, the sample stage is positioned proximal to the second region. An illumination device is configured to illuminate a portion of the first exposed region, and a second translation mechanism is configured to translate the illumination device along a second axis substantially perpendicular to the first axis.

Abstract: A gas flux chamber assembly is provided comprising a soil collar and a chamber. The chamber is moved between first and second positions, wherein the chamber is positioned on the soil collar in the first position and is positioned outside of an area above the soil collar in the second position. In operation, the chamber is first lifted off of the soil collar and is then rotated, about a rotational axis substantially parallel to the soil collar axis, outside of the area above the soil collar. These acts are reversed to move the chamber from the second position to the first position.
