13DV-7365 APPARATUS AND METHOD FOR OPTICAL CLEARANCE DETERMINATION ABSTRACT OF THE DISCLOSURE Clearance determination is made between an edge of a translating member, e.g., a rotating blade member, and a relatively stationary second number, e.g., a shroud. In one form, an optical probe is provided for directing light from a light source to the edge and for collecting light scattered back from the edge. The probe includes first and second adjacent channels, optically separated by an opaque baffle. Probe output means and signal processing means are provided for developing a stored or displayed representation of the instantaneous clearance between each of a plurality of rotating blades and a stationary member, such as the turbine blade shroud. The probe may employ a continuous or intermittent light source. Synchronization techniques are provided for use with the intermittent light source wherein the light source is turned on only when needed to make the appropriate clearance determination. Other embodiments are disclosed.
