Abstract: An apparatus can include a vessel, a reference surface, a preload, a scan actuator, and a transmitter. The reference surface can form a structural loop with a detector. The preload can be configured to urge the vessel to contact an area on the reference surface. The scan actuator can be configured to slide the vessel along the reference surface in a scan dimension. The transmitter can be configured to direct signal from the vessel to a detector and/or direct energy from an energy source to the vessel, when the vessel is urged by the preload to contact the reference surface.
