High Resolution CCD Polarization Imaging Sensor
نویسنده
چکیده
We present a novel polarization imaging sensor by monolithically integrating aluminum nanowire optical filters with an array of CCD imaging elements. The CCD polarization image sensor is composed of 1000 by 1000 imaging elements with 7.4m pixel pitch. The image sensor has a dynamic range of 65dB and signal-to-noise ratio of 45dB. The CCD array is covered with an array of pixel-pitch matched nanowire polarization filters with four different orientations offset by 45. The complete imaging sensor is used for real-time reconstruction of the shape of various objects.

Mueller Matrix Imaging Polarimeter for UV Metrology
The University of Arizona Polarization Laboratory with support from the Jet Propulsion Laboratory (JPL) has assembled and is currently calibrating a UV Mueller matrix imaging polarmeter (UV-MMIP). The desire for more accurate polarimetric and radiometric sensors drives the need for stringent polarization requirements and the ability to more precisely measure system and component polarization be...
متن کاملColor Super-Resolution from a Single CCD
Limitation in the resolution of CCD image sensors has provided motivation to enhance the resolution of images. Super-resolution has been applied mainly to grayscale images, and producing a high-resolution color image from a single CCD sensor has not been discussed thoroughly. This work aims at producing a high-resolution color image directly from ”color mosaic” images obtained by a singleCCD wi...

We present the design and optimization of a 30um CMOS Image Sensor (CIS) pixel. This pixel is embedded in a sensor working in burst mode at speeds up to 5Mfps and high resolution (0.7Meg). Such performance is achieved using two dimensional CCD Memory bank at each pixel which was manufactured using a 0.18um well established CIS Process.

متن کاملSurface Plasmon Resonance Phase-Sensitive Imaging (SPR-PI) Sensor Based on a Novel Prism Phase Modulator
A novel prism phase modulator (PPM) for phase difference modulation between pand s-polarization lights in a surface plasmon resonance phase-sensitive imaging sensor is proposed in this paper. The PPM consists of a rhombic prism (to obtain a curve of phase difference between the two polarizations), a rotation stage and a mirror. The PPM shows great modulation stability and helps to achieve a hig...
متن کاملOne method for HJ-1-A HSI and CCD data fusion
HJ-1-A satellite, developed by China independently, was equipped with two sensors of Hyper Spectral Imager (HSI) and multispectral sensor (CCD). In this paper, we examine the benefits of combining data from CCD data (high-spatial-resolution, low-spectral-resolution image) with HSI data (low -spatial-resolution, high -spectral-resolution image). Due to the same imaging time and similar spectral ...
