Claim 12:
13. A system for inspecting a surface, comprising:
an optical system including at least one optical element;
a gated camera; and
a control system configured to perform a set of acts comprising:
causing the at least one optical element to direct a first pulse of light having a first wavelength to a first point along a scan line and a second pulse of light having a second wavelength to a second point along the scan line,
causing the gated camera to record a first fluorescent response of the surface to the first pulse of light and a second fluorescent response of the surface to the second pulse of light,
causing the at least one optical element to direct a third pulse of light having the first wavelength to the second point and a fourth pulse of light having the second wavelength to the first point, and
causing the gated camera to record a third fluorescent response of the surface to the third pulse of light and a fourth fluorescent response of the surface to the fourth pulse of light.
