Abstract
A system comprising a substrate having thereon a multiphoton curable photoreactive composition, a light source that emits a light beam comprising a plurality of wavelengths onto at least one region of the composition on the substrate, and a detector that detects a portion of light reflected from the composition to obtain a location signal with respect to the substrate, wherein the location signal is based at least on a wavelength of the reflected light.
