Proposed for the first time is a novel calibration empowered minimalistic multi-exposure image processing technique using measured sensor pixel voltage output and exposure time factor limits for robust camera linear dynamic range extension. The technique exploits the best linear response region of an overall nonlinear response image sensor to robustly recover via minimal count multi-exposure image fusion, the true and precise scaled High Dynamic Range (HDR) irradiance map. CMOS sensor-based experiments using a measured Low Dynamic Range (LDR) 44 dB linear region for the technique with a minimum of 2 multi-exposure images provides robust recovery of 78 dB HDR low contrast highly calibrated test targets.

A sample cell for observing the Shpol'skii effect at 77 K is described and analytically assessed. The cell employs fiber-optic light guides to transport excitation and emission radiation. The system is compact, inexpensive, and simple to construct from commercially available laboratory components, and it alleviates several problems inherent in conventional refrigerated-cell designs. Detection limits for anthracene, coronene, and pyrene obtained with the sample cell are 8.8 × 10−8 M, 8.4 × 10−7 M, and 3.5 × 10−7 M, respectively. The linear dynamic range for each compound is 2 to 3 orders of magnitude.
