Calibration based Minimalistic Multi-Exposure Digital Sensor Camera Robust Linear High Dynamic Range Enhancement Technique Demonstration [PDF]
, 2021 Demonstrated for a digital image sensor based camera is a calibration target optimized method for finding the Camera Response Function (CRF). The proposed method uses localized known target zone pixel outputs spatial averaging and histogram analysis for saturated pixel detection. Using the proposed CRF generation method with a 87 dB High Dynamic Range (

Binding occupational exposure limits for carcinogens in the EU – good or bad?
Scandinavian Journal of Work, Environment & Health, 2019 The European Union (EU) has increased its efforts to counteract cancer due to occupational exposure. This is done by several means, including more active use and revision of the Carcinogen Directive (1), launch of the Roadmap on Carcinogens (2) and the ...

New Results from the X-ray and Optical Survey of the Chandra Deep Field South: The 300ks Exposure [PDF]
, 2001 We present results from 300 ks of X-ray observations of the Chandra Deep Field South. The field of the four combined exposures is now 0.1035 deg^2 and we reach a flux limit of 10^{-16} erg s^{-1} cm^{-2} in the 0.5-2 keV soft band and 10^{-15} erg s^{-1}
