Image smear, produced by the shutterless operation of frame-transfer CCD detectors, can be detrimental for many imaging applications. Existing algorithms used to numerically remove smear do not contemplate cases where intensity levels change considerably between consecutive frame exposures. In this report, we reformulate the smearing model to include specific variations of the sensor illumination. The corresponding desmearing expression and its noise properties are also presented and…

Fast computation of readout smear correction for framestore CCD based images
It is shown, that the correction in the standard and in the periodic case are convolution operations, which allow for faster computations and offer transfer functions, which allows the use of unshuttered framestore CCDs on autonomous astronomical observations.
Star smear removal for full-frame charge-coupled device images based on Gaussian fitting
Abstract. Image smear, produced by the shutter-less operation of full-frame charge-coupled device (CCD) sensors, greatly affects the performance of target detection, the centering accuracy, and

A multichannel visible spectroscopy system for the ITER-like W divertor on EAST.
The spectroscopic diagnostic is routinely operated in EAST discharges with absolute optical calibrations applied before and after each campaign, monitoring photon fluxes from impurities and H recycling in the upper divertor.
Spectroscopic investigations of detachment on TCV: Investigating the role of atomic physics on the ion current roll-over and the dynamics of detachment in TCV
The process of divertor detachment, whereby heat and particle fluxes to divertor surfaces are strongly reduced, is required to reduce heat loading and erosion in a magnetic fusion reactor. In this


Smear correction for frame transfer charge-coupled-device cameras.
A simple algorithm is described and demonstrated for the removal of smear from images obtained with a frame transfer CCD camera. The algorithm requires specification of only a single parameter, which

The model predictions match the experiments performed with two 12-bit-depth interline CCD cameras (MegaPlus ES 4.0/E incorporating the Kodak KAI-4000M CCD sensor with 4 megapixels) and two constant values are needed to fit the proposed calibration model and predict the error from the readout procedure.
