CPC G01H 9/00 (2013.01) | 16 Claims |
1. A method for determining one or more vibration frequencies of a single cantilever, the method comprising:
over a period of time, repeating the steps of:
directing a fixed source of collimated light set at a known angle toward the single cantilever;
receiving some of the directed light as reflected from the cantilever;
determining a position where the reflected light is received; and
for each of at least some of determined reception positions, associating a time of reception with the determined reception position; and
based, at least in part, on at least some of the associated times of reception, calculating said one or more vibration frequencies of the cantilever;
wherein the cantilever is a layered-material strip; and based, at least in part, on the calculated one or more vibration frequencies of the layered-material strip, determining a characteristic related to the layered-material strip.
