Abstract
Solar-blind ultraviolet cameras with image intensifier with CMOS detector typically use
various count methodologies to measure the optical energy of an electrical corona. However,
these count methodologies are non-radiometric without considering parameters such as
distance, focus-, zoom-, and gain setting of a camera. An algorithm which considers the
calibration and radiometric measurement of optical energy for the slow frame rate intensifier
type cameras is presented. Furthermore, it is shown how these calibration data together with
the flowcharts are used for the conversion from raw measured data to radiometric energy
values.
