Digital holographic imaging of thermal signatures and its use in inhomogeneity identification

Microsphere-Assisted Digital Holographic Microscopy Integrated with On-Line Thermal Lens Spectrometry for 3d Imaging and Enhanced Photothermal Detection

“…Due to the high sensitivity of TL measurement method, it is considered as a suitable optical characterization for a variety of samples, especially for detection of low concentrations of analytes in low absorbing samples as well as a photothermal detector integrated with gel electrophoresis [12][13][14] . It is also remarkable that, since DHM can extract the optical phase difference function of the sample, it may be considered as an alternative to measure the absorption coefficient using the TL effect 15,16 .…”
