We propose a sampling scheme that can perfectly reconstruct a collection of spikes on the sphere from samples of their lowpass-filtered observations. The proposed algorithm can reconstruct K spikes from (K + √K)2 spatial samples, thus improving over previously known FRI sampling schemes on the sphere by a factor of up to four. Further, we show how multiple sound source localization (SSL) by a spherical...
We consider the problem of estimating an unknown parameter from a finite collection of different statistical experiments. The measurements are taken sequentially. Based on the observations made so far, we adaptively select the next experiment that provides the most information about the parameter. Summarizing past information with finite memory, we present a general framework for efficient adaptive...
We report for the first time the combination of a quartz-based photonic crystal (PC) with a detection instrument designed to perform label-free (LF) and enhanced fluorescence (EF) imaging for antibody microarray applications. Label-free detection is used to quantify binding density of immobilized capture antibodies. Angle-scanning approach is implemented to achieve more uniform fluorescence enhancement...
This paper introduces techniques for the electronic variation & automatical control of exposure in solid-state image sensors. A novel electronic aperture and a simple exposure controller are described, which have been integrated on chip with a CMOS image sensor array. The technique can achieve a wide range exposure control of 40,000:1. This is equivalent to 15 stops of a mechanical iris system.
