Телевизионная измерительная система наносекундного разрешения

Телевизионная измерительная система наносекундного разрешения

Abstract

Описана телевизионная измерительная система на базе высокоскоростной видеокамеры с наносекундным электронным затвором и микроканальным фотоумножителем. Обнаруженная нелинейность системы обусловлена архитектурой CMOS сенсора приемника изображений. Экспериментально полученные данные позволяют ввести для данной видеокамеры калибровочную шкалу с погрешностью не более 2%, связывающую яркость пикселей регистрируемого изображения и яркостную температуру, соответствующую тепловому излучению эталонной лампы.

The article describes a model of transfer function of optoelectronic measuring system based on high speed camera with a nanosecond electronic shutter. The observed non-linearity is due to the architecture of the system CMOS image sensor receiver. The experimental data allow to introduce this camera calibration scale with an accuracy of 2%, the brightness of the pixels linking the registered image and the brightness temperature corresponding to thermal radiation standard lamp.
