Abstract
A mid-infrared photothermal microscopy system images a sample. A mid-infrared optical source generates a mid-infrared beam which is directed along a first optical path to reach the substrate on a first side and heat the sample. A probe light source generates a probe light which is directed along a second optical path to reach the substrate on a second side and illuminate the sample. A first laser scanner is positioned along the first optical path and configured to rotate to redirect light and scan the sample with the mid-infrared beam. A second laser scanner is positioned along the second optical path and configured to rotate to redirect light and scan the sample with the probe light. The laser scanners each include at least one mirror driven to rotate such that the mid-infrared beam and the probe light scan the sample synchronously.
