4 facteur de multiplication de photocourant
коэффициент умножения фототока лавинного фотодиода
Отношение фототока лавинного фотодиода к его первичному фототоку, который протекал бы в лавинном фотодиоде при отсутствии в нем эффекта лавинного умножения при том же рабочем напряжении, интенсивности засветки и прочих равных условиях.
Обозначение
Mф
Mph
Примечание
Если фототок измеряют при засветке всего чувствительного элемента, то получают интегральный коэффициент умножения, а при точечной засветке - локальный коэффициент умножения.
