ABSTRACT:
A probe cleaning system automatically detects a surface of a probe cleaning device during a cleaning process by providing a predetermined finish on the surface of the probe cleaning device. The predetermined finish can include a textured or machined finish or a marking, such that the predetermined finish provides contrast against the surface. Cameras in the system automatically focus on the surface, with the predetermined finish. This in-focus condition is related to a distance between probes and the surface. Once an in-focus condition is determined, the system performs an automated cleaning process by interacting the probes with the probe cleaning device.
