1. A probe assembly for transmitting radiation from a pair of radiation sources to a rotating component surface, the probe assembly comprising:
a probe body on a stationary component;
a pair of sensor assemblies coupled to the probe body, each sensor assembly including:
a plurality of prisms coupled to the probe body, each prism of the plurality of prisms having a distinct angular orientation to direct radiation from a respective radiation source to the rotating component surface off-axis with respect to an axis of the respective radiation source of the pair of radiation sources and with less directional variation than radiation from the respective radiation source.
