  • Patent number: 11867620
    Abstract: Systems and methods for detecting photothermal effect in a sample are described herein. In these systems and methods, a pump source is configured to generate a pump pulse train, a probe source is configured to generate a probe pulse train and is synchronized with the pump pulse train, and a camera collects the resulting data. The camera is configured to collect a first signal corresponding to a hot frame, wherein the hot frame includes visible probe beam as modified by a pump beam and a second signal corresponding to a cold frame, wherein the cold frame includes visible probe beam that has not been modified by a pump beam. A processor can subtract the second signal from the first signal to detect the photothermal effect.

  • Publication number: 20230408805
    Abstract: Microscopic analysis of a sample includes a system using dark-field illumination. A mid-IR optical source generates a mid-infrared beam, which is directed onto the sample to induce a temperature change by absorption of the mid-infrared beam. A visible light source generates a light illuminating the sample on a substrate and creating a scattered field and a reflected field along a collection path of the system. A pupil mask is positioned along the collection path to block the reflected field while allowing the scattered field to pass therethrough. A camera is positioned at an end of the collection path to collect the scattered field and generate a dark-field image of the sample.
