Abstract
В заявке описана интерферометрическая система, в которой с помощью выходного средства 4 формирования изображений посредством проходной системы 6.1 отражателей отображают на плоскости 7 вывода плоскость 3.3 изображений средства 3.1 формирования изображений в объектной ветви, при этом в плоскости 3.4 изображений средства 3.2 формирования изображений в опорной ветви расположена дифракционная решетка отражательного типа 5, которую выходное средство 4 формирования изображений также отображает посредством проходной системы 6.2 отражателей на плоскость 7 вывода интерферометра, на которой формируют ахроматическую внеосевую голограмму за счет интерференции волн, поступающих как из объектной ветви, так и опорной ветви, и на которой находится детектор. Проходные системы 6.1 и 6.2 отражателей регулируют таким образом, чтобы оси обеих ветвей совпадали при достижении плоскости 7 вывода и проходили параллельно нормали плоскости 7 вывода, а осевой луч, преломленный дифракционной решеткой отражательного типа 5 под углом α, достигал плоскости 7 вывода под углом β, при этом между углами β и α существует зависимость sin(β)=sin(α)/m, в которой m означает кратность увеличения выходного средства 4 формирования изображений. Описанная система позволяет осуществлять голографическое формирование изображения объекта с помощью волн с низкой когерентностью, например, белого света распределенного источника света. Некогерентные волны позволяют формировать изображения объектов, погруженных в рассеивающие среды. Формирование изображений осуществляют в реальном времени. Может использоваться одна зарегистрированная в цифровой форме голограмма части наблюдаемого объекта для
