By mwkudenoAbstract: In optical thin-films and surfaces, geometric phase is utilized to control the phase beyond that possible through optical path differences. Geometric-phase lenses, which are... |Proceedings
By mwkudenoAbstract: A prior simulation-only study of aspherical phase profiles [Hornburg et al, Proc SPIE 10743, 10743-4 (2018)] in geometric-phase lenses (GPLs) indicated that aspherical doublet... |Proceedings
By mwkudenoAbstract: The design and experimental results of a snapshot spatially heterodyned imaging Fourier transform (SHIFT) spectropolarimeter are presented. The sensor utilizes common-path interferometry, which lends improved... |Proceedings
By mwkudenoAbstract: The design of a Fraunhofer line optical correlator is detailed. The instrument described herein correlates a reflected solar spectrum against multiple Fraunhofer absorption lines to estimate... |Proceedings
By mwkudenoAbstract: This paper presents a reconstruction algorithm for the Spatial-Spectral Multiplexing (SSM) optical system. The goal of this algorithm is to recover the three-dimensional spatial... |Proceedings
By mwkudenoAbstract: Hyperspectral imaging provides a highly discriminative and powerful signature for target detection and discrimination. Recent literature has shown that considering additional target characteristics, such as... |Proceedings
By mwkudenoAbstract: Polarization spatial heterodyne interferometry (PSHI) allows for the development of compact, vibration insensitive, high spectral resolution sensors. Introducing the imaging qualities of a lenslet... |Proceedings
By mwkudenoHyperspectral polarimetry is demonstrated to measure the spectrum and polarization state of a scene. This information is important to identify material properties for applications such... |Proceedings
By mwkudenoThe concept of a passive far-field imaging system, using a unique spatial-spectral multiplexing (SSM) technique, is presented. The described SSM technique uses spectrally resolved interferometry to... |Proceedings
By mwkudenoAbstract: Early diagnosis of glaucoma, which is a leading cause for visual impairment, is critical for successful treatment. It has been shown that Imaging polarimetry... |Proceedings
By mwkudenoUltraspectral sensing has been investigated as a way to resolve terrestrial chemical fluorescence within solar Fraunhofer lines. Referred to as Fraunhofer Line Discriminators (FLDs), these sensors... |Proceedings
By mwkudenoPhase error is common in reflective interferometers, such as the Michelson. This yields highly asymmetric interferograms that complicate the post-processing of single-sided interference data. Common... |Proceedings
By mwkudenoAbstract- Reflectance measurements have been a long standing means of quantifying chlorophyll, and other chemical contents, within vegetation. Conventional metrics that are common include normalized... |Proceedings
By mwkudenoAbstract: We present a novel and inexpensive Stokes imaging spectropolarimeter based on the Snapshot Hyperspectral Imaging Fourier Transform (SHIFT) spectrometer. A rotating quarter wave plate...
