Claim 0:
1. A system for characterizing a sample using second harmonic generation, the system comprising:
a sample holder configured to support a sample;
an optical source configured to direct a light beam onto said sample to produce second harmonic generation from said sample;
an array beam generator configured to generate a plurality of beams using the light beam received from the optical source;
a focusing lens configured to focus light from said optical source onto said sample;
a scanner disposed in an optical path between the array beam generator and the focusing lens, the scanner configured to scan the plurality of the beams received from the array generator over the sample, by redirecting them;
an optical detection system configured to receive second harmonic generated light from said sample, said optical detection system comprising at least one detector array;
a translation stage configured to translate said sample with respect to said optical source and said at least one detector array;
projection optics configured to project a 2D array of beams of second harmonic generation light from said sample onto said at least one detector array; and
processing electronics configured to receive signals from said at least one detector array;
wherein the scanner scans the plurality of beams over separate regions of the sample in parallel and in a first direction and the translation stage scans the sample in a second direction perpendicular to the first direction, and
wherein the system generates a map of a distribution of the second harmonic generated light over an area on the sample by combining data received from the detector array.
