Abstract
Disclosed are methods that, by not physically touching the material being measured, can measure the material's differential, response quite accurately. A collimated light shines on the material under test, is reflected off it, and is then captured by a recording device. The position where the reflected light is captured is used to calculate the deflection of the material. Dynamic characteristics of the material under test may be determined from the deflection measurement. The vibration frequency or vibration amplitude of a cantilever can be determined by repeated deflection measurements, all without physically touching the cantilever during the measurement process.
