A moving property of a target is measured as the target travels toward a target space. The target including a component that emits light when converted to a plasma. A diagnostic probe system is interacted with a current target moving toward the target space. The interaction occurs prior to the current target entering the target space and after an immediately preceding target has interacted with a prior radiation pulse in the target space. First and second light that is produced at least in part from the interaction between the diagnostic probe system and the current target is detected prior to the current target entering the target space and after an immediately preceding target has interacted with the prior radiation pulse in the target space. One or more moving properties of the current target are determined based on an analysis of the detected first and second light.

Apparatus and methods for determining belt speed and pitch using correlation techniques. The apparatus includes a pair of rangefinders separated by a predetermined distance. The rangefinders each measure the distance to the belt at two positions separated from each other in the direction of belt travel. The apparatus creates at least one time-series profile record corresponding to the profile of a belt. The time delays between occurrences of a regularly spaced topographical feature in the belt's profile are used by a processor to compute belt pitch and speed. Correlation techniques are used for robust results.
