摘要：
Methods and apparatus are provided for imaging a response of a sample to radiative heating. A method in accordance with one embodiment has steps of: illuminating a first area of the sample with a radiative heating beam； illuminating a portion of the first area with a probe beam； collecting light exiting the sample due to interaction of the probe beam with the sample； superimposing the light exiting the sample with a reference beam derived from the probe beam, wherein the reference is characterized by an optical phase relative to the probe beam； detecting a spatial portion of the light exiting the sample and the reference beam with at least one detector to generate an interference signal； and processing the interference signal to obtain an image of the sample associated with absorption of the radiative heating beam.
