A novel multi-object spectrometer (MOS) is being explored for use as an adaptive performance-driven sensor that tracks moving targets. Developed originally for astronomical applications, the instrument utilizes an array of micromirrors to reflect light to a panchromatic imaging array. When an object of interest is detected the individual micromirrors… (More)
The presence of a third body orbiting an eclipsing binary system has long been known to ooset the system about a binary/third-body barycenter causing periodic variations in the time of eclipses (due to the increasing or decreasing light travel time). Recent increased precision in the timing of eclipse minima should allow a survey of the prevalence of… (More)
An optical tracking sensor that produces images containing the state of polarization of each pixel can be implemented using individual wire-grid micropolarizers on each detector element of a solid-state focal plane array. These sensors can significantly improve identification and tracking of various man-made targets in cluttered, dynamic scenes such as… (More)
A lightcurve of the eclipsing binary CM Draconis has been analyzed for the presence of transits of planets of size ≥ 2.5 Earth-radii (R e), with periods of 60 days or less, and in co-planar orbits around the binary system. About 400 million model lightcurves, representing transits from planets with periods ranging from 7 to 60 days, have been… (More)
Computer aided object tracking is a subject of increasing interest. The applications for these tracking algorithms are widespread; from homeland security and surveillance to the study of animal behavior. In past years, the visible part of the electromagnetic spectrum has been the dominant regime in which algorithms have been developed. This is in part due… (More)
This paper investigates Foveons X3 sensor  , which vertically stacks three sensor layer that absorb light of different colors, talks about the operating principle of this type of sensors, and the advantages and disadvantages of such design.
The DMD TM (Digital Micromirror Device) has become an integral part of the instrumentation for many applications. Prior characterization of this device has been focused on its use in DLP TM (TI Digital Light Processing) projector applications where a collimated wavefront impinges on the DMD. The results of such investigations are not applicable to using… (More)
