Low Voltage Electron Multiplying CCD in a CMOS Process
Low light level and high-speed image sensors as required for space applications can suffer from a decrease in the signal to noise ratio (SNR) due to the photon-starved environment and limitations of the sensor’s readout noise. The SNR can be increased by the implementation of Time Delay Integration (TDI) as it allows photoelectrons from multiple exposures to be summed in the charge domain with ...
متن کاملRecent Enhancements to Interline and Electron Multiplying CCD Image Sensors †
This paper describes recent process modifications made to enhance the performance of interline and electron-multiplying charge-coupled-device (EMCCD) image sensors. By use of MeV ion implantation, quantum efficiency in the NIR region of the spectrum was increased by 2×, and image smear was reduced by 6 dB. By reducing the depth of the shallow photodiode (PD) implants, the photodiode-to-vertical...
متن کاملKitt Peak Multi-Tasking FORTH-It
An overview of the Kitt Peak National Observatory (KPNO) real-time environment is presented. The eleven optical telescopes at Kitt Peak employ a variety of experimental instruments, including Fourier Transform Spectrometers and large array digital cameras, that impose a diverse set of real-time requirements. Presented next will be a historical perspective of FORTH and KPNO over the last decade ...
متن کاملGuide to the Kitt Peak Coude Slit Reduction Task DOSLIT
The IRAF kpcoude.slit package is specialized for the extraction, sky subtraction, wavelength calibration, and flux calibration of Kitt Peak coude slit spectra. It contains the general tools needed for each of the reduction steps. However, the main emphasis of this package is the task doslit to streamline the complete data reduction. This guide describes what this task does, it’s usage, and para...
متن کاملHigh resolution x-ray and -ray imaging using a scintillator-coupled electron-multiplying CCD
Over the last decade the rapid advancements in CCD technology have lead to significant developments in the field of low-light-level, Electron-Multiplying CCDs (EM-CCDs). The addition of a gain register before output allows signal electrons to be multiplied without increasing the external noise. This low effective readout noise, which can be reduced to the sub-electron level, allows very small s...
