Non-linearity in photothermal radiometric imaging

Non-linear effects occurring in photothermal microscopes based on principle of photothermal radiometry are studied as a hnction of the laser power and of the modulation frequency. For stainless steel, a second harmonic component of up to 11 % of the hndamental amplitude is found. Phase shifts of up to 20 degrees are observed as a hnction of the modulation frequency. The nonlinearity is mainly d...

Radiometric Characterization of Spectral Imaging for Textual Pigment Identification

Digital imaging of cultural heritage artifacts has become a standard practice. Typically, standard commercial cameras, often commodity rather than scientific grade cameras, are used for this purpose. Commercial cameras are optimized for plausible visual reproduction of a physical scene with respect to trichromatic human vision. However, visual reproduction is just one application of digital ima...

On-Orbit Radiometric Calibration for a Space-Borne Multi-Camera Mosaic Imaging Sensor

As the core and foundational technology, on-orbit radiometric calibration of a space-borne sensor is of great importance for quantitative remote sensing applications. As for the space-borne multi-camera mosaic imaging sensor, however, the currently available on-orbit radiometric calibration method cannot carry out the integrated processing of on-orbit absolute radiometric calibration and relati...
