“…The technique is used at e2v and the LRF is sampled with a resolution of 1/8 pixel [13]. e2v estimate the MTF of the CCD-273 devices as part of the ESA pre-development phase for the VIS CCD detectors (Euclid) [10]. The slit is focused using a 20x objective lens, the measured LRF points are interpolated to get a regularly sampled The results of MTF obtained in horizontal and vertical orientations of the slit are presented.…”

ABSTRACT:The Institute for Optical Sensor Systems was involved in many international space projects in recent years. These include, for example, the fokal plane array (FPA) of the hyperspectral sensors ENMAP or Sentinel-4, but also the FPA for the high resolution FPA for Kompsat-3. An important requirement of the customer is the measurement of the detector MTF for different wavelengths. A measuring station under clean room conditions and evaluation algorithms was developed for these measurements. The measurement setup consist of a collimator with slit target in focus for illumination at infinity, a gimbal mounted detector facing an auxiliary lens in front, a halogen lamp with monochromator or filter, as well as optical and electrical ground support equipment. Different targets and therefore also different measurement and data evaluation opportunities are possible with this setup. Examples are slit, edge, pin hole but also a Siemens star. The article describes the measurement setup, the different measuring and evaluation procedures and exemplary results for Sentinel-4 detector.

“…Dynamic effects on charge collection in sensors in general, and the "brighter-fatter effect" (hereafter: BFE) in particular are becoming ever more important; being strongly exhibited in thick, fully depleted, back biased CCDs such as the e2v CCD250 LSST sensor candidate device, and having been observed also in testing of CCD273 devices for the ESA Euclid mission [1][2][3][4] .…”

Models for dynamic correlated charge collection effects in thick CCDs

et al. 2015

View full text Add to dashboard Cite

Dynamic charge collection effects in thick CCDs have received interest in recent years, due to the performance implications for both ground and space based precision optical astronomy. The phenomena manifest as the "brighter -fatter" effect in Point Spread Function (PSF) measurements, and nonlinearity and signal dependence in spatial autocorrelation and photon transfer measurements. In this paper we present validation results from simple, analytically based predictive models for this effect, using an e2v CCD250. The model is intended to provide estimations for predicting device performance based on design parameters.
