Dawson and Foss (1985) have reported that each of five naive budgerigars (Melopsittacus undulatus ) after watching a demonstrator budgerigar use one of three different methods of opening a covered food dish, used the same method as its respective demonstrator to uncover its own food fish. Our first attempt to replicate Dawson and Foss' experiment was(More)
—A fully-integrated single-photon avalanche diode (SPAD) and time-to-digital converter (TDC) array for high-speed fluorescence lifetime imaging microscopy (FLIM) in standard 130-nm CMOS is presented. This imager is comprised of an array of 64-by-64 SPADs each with an independent TDC for performing time-correlated single-photon counting (TCSPC) at each(More)
We present the design and characterization of a single-photon avalanche diode (SPAD) fabricated with a standard 0.13µm complementary metal-oxide-semiconductor process. We have developed a figure of merit for SPADs when these detectors are employed in high frame-rate fluorescent lifetime imaging microscopy, which allows us to specify an optimal bias point(More)
