Claims (9)

1. Оптическое устройство, содержащее средство динамической фильтрации источника света высокой яркости, отличающееся тем, что указанное средство фильтрации образовано при помощи зеркала, имеющего зону наименьшего отражения, и средства слежения за положением указанного зеркала, в функции положения источника света высокой яркости в изображении, образованном на указанном зеркале (1).1. An optical device containing means for dynamically filtering a high-brightness light source, characterized in that said filtering means is formed using a mirror having a zone of least reflection, and means for tracking the position of said mirror, as a function of the position of the high-brightness light source in the image formed on the specified mirror (1). 2. Оптическое устройство по п.1, отличающееся тем, что зона наименьшего отражения образована при помощи отверстия.2. The optical device according to claim 1, characterized in that the zone of least reflection is formed using the hole. 3. Оптическое устройство по п.2, отличающееся тем, что указанное отверстие образовано в виде конического отверстия в основании зеркала.3. The optical device according to claim 2, characterized in that said hole is formed as a conical hole in the base of the mirror. 4. Оптическое устройство по п.3, отличающееся тем, что коническое отверстие в основании зеркала имеет угол вершины от 40° до 60°.4. The optical device according to claim 3, characterized in that the conical hole in the base of the mirror has an apex angle of 40 ° to 60 °. 5. Оптическое устройство по п.3. отличающееся тем, что отверстие имеет апертуру от 1,2 до 2,5 мм.5. The optical device according to claim 3. characterized in that the hole has an aperture from 1.2 to 2.5 mm. 6.

The optical device according to claim 2, characterized in that the zone of least reflection is formed by a diaphragm of variable cross section. 7. Оптическое устройство по п.1, отличающееся тем, что зеркало образовано матрицей ориентируемых микрозеркал, управляемых таким образом, чтобы образовать зону, в которой отражение происходит в направлении, которое отличается от направления отражения основного пучка.7. The optical device according to claim 1, characterized in that the mirror is formed by an array of orientable micromirrors controlled in such a way as to form a zone in which reflection occurs in a direction that differs from the direction of reflection of the main beam. 8. Оптическое устройство по п.1, отличающееся тем, что зона наименьшего отражения образована при помощи полуотражающей зоны.8. The optical device according to claim 1, characterized in that the least reflection zone is formed using a semi-reflective zone. 9. Оптическое устройство по п.1, отличающееся тем, что оно дополнительно содержит анализатор изображения, получающий часть падающего пучка и выдающий сигнал слежения за положением зеркала.9. The optical device according to claim 1, characterized in that it further comprises an image analyzer receiving a portion of the incident beam and issuing a tracking signal for tracking the position of the mirror.
