The IRCSP rotates incident linearly polarized light using the combination of a quarter\u0000waveplate with a fast axis at 45◦ and a thick birefringent crystal; the output polarization state’s orientation is\u0000then a function of wavelength. To modulate and then measure the rotated light, a subsequent wiregrid linear\u0000polarizer tilted at 20◦ generates two output paths with opposite polarities in reflection and transmission to enable\u0000joint radiometric and polarimetric measurement and correct for atmospheric attenuation. The two symmetric\u0000optical paths following the linear polarizer each consist of a diffraction grating and uncooled microbolometer to\u0000simultaneously measure the resulting intensity fringes. Angle and degree of linear polarization (AOLP, DOLP) are\u0000retrieved across 8.5-12.5 µm with 1 µm resolution using Fourier decomposition of the modulated spectrum. The IRCSP will not only measure H-V variance but will produce the first full linear Stokes measurements\u0000(I, Q, and U) of upper-tropospheric cirrus clouds in the LWIR. Following thermal and polarimetric calibration,\u0000the polarimeter is expected to achieve 0.5% DOLP accuracy over 90% of the spectral band.","PeriodicalId":437141,"journal":{"name":"Polarization Science and Remote Sensing IX","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115856640","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Owing to the flexibility with which their constituent elements may be engineered, metasurfaces allow for point-to-point polarization control on a subwavelength scale. Metasurfaces, then, represent an exciting new platform for polarization optics.\u0000\u0000A single metasurface may combine many different polarization-dependent functionalities that would ordinarily be spread out over many optical elements. We describe how, through relatively simple optimization methods, a metasurface producing arbitrarily specified polarization states can be designed. This functionality is equivalent to a traditional diffraction grating with individual waveplate optics on each order; here, all the necessary polarization optics can be integrated into a flat, efficient, and ultrathin metasurface optical element. Moreover, such a metasurface can be used in a reverse configuration as a parallel snapshot polarimeter with no need for additional polarization optics. We present a detailed experimental characterization of this device in the visible spectral region and a comparison of the performance of the metasurface to a commercially available rotating waveplate polarimeter.\u0000\u0000Metasurfaces can enable compact, miniaturized sensors for polarimetry and polarization imaging. We will conclude with a perspective on these possibilities and their implications for remote sensing. Metasurface polarization optics can overcome limitations of previous diffractive/grating based polarimetry schemes are potentially of significant interest to the imaging polarimetry community.","PeriodicalId":437141,"journal":{"name":"Polarization Science and Remote Sensing IX","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127185651","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This method utilizes the structural similarities between polarization vision and color vision so that the full linear polarization information is depicted in a single image. Recent developments have attempted to address issues, arising from the fact that the HSV color space is not an accurate model of human color vision, by mapping the polarization channels of intensity, degree, and angle to the color channels of lightness, colorfulness, and hue defined in the perceptually uniform color space CAM02-UCS. While the theoretical benefits of this method have been demonstrated using metrics of perceptual uniformity and channel independence, the practical benefits to human observers has not been studied. In this user study, the two methods are compared using a series of forced-choice questions on the perceived magnitude differences in DoLP value to determine 1) which method produces fewer errors, 2) which method produces a more linear scale in degree of polarization perception, 3) whether the perception of degree of polarization is independent of intensity and angle of polarization.","PeriodicalId":437141,"journal":{"name":"Polarization Science and Remote Sensing IX","volume":"28 39","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131805175","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
