PCA-based denoising method for division of focal plane polarimeters.
Division of focal plane (DoFP) polarimeters are composed of interlaced linear polarizers overlaid upon a focal plane array sensor. The interpolation is essential to reconstruct polarization information. However, current interpolation methods are based on the unrealistic assumption of noise-free images. Thus, it is advantageous to carry out denoising before interpolation. In this paper, we propo...
متن کاملFOCAL POINT AND FOCAL K-PLANE
This paper deals with the basic notions of k-tautimmersions . These notions come from two special cases; that is, tight and taut immersions. Tight and taut based on high and distance functions respectively and their basic notions are normal bundle, endpoint map, focal point, critical normal. We generalize hight and distance functions to cylindrical function and define basic notions of k-taut ...
متن کاملDivision-of-focal-plane spectral-polarization imaging sensor
We have designed, fabricated and tested a division-of-focal-plane spectral-polarization imaging sensor by the monolithic integration of aluminum nanowire linear polarization filters to a spectrally sensitive CMOS imaging array. The sensor has a pixel pitch of 5.0 μm and an imaging array size of 168 by 256 pixel elements. Each pixel comprises three layers of vertically stacked photodetectors, ea...
متن کاملCalibration of Millimeter-Wave Polarimeters Using a Thin Dielectric Sheet
We present the theory and application of a novel calibration system for millimeter and microwave polarimeters. The technique is a simple extension of the conventional wire-grid approach, but employs a thin dielectric sheet rather than a grid. The primary advantage of this approach is to obtain a calibration signal that is only slightly polarized, which can be beneficial for certain applications...
متن کاملMethods and Geometry for Plane-Based Self-Calibration
We consider the problem of camera selfcalibration, from images of a planar object with unknown Euclidean structure. The general case of possibly varying focal length is addressed. This problem is non-linear in general. One of our contributions is a non-linear approach, that makes abstraction of the (possibly varying) focal length, resulting in a computationally efficient algorithm. In addition,...
