とを特徴とする光遅延装置。[Claims for Utility Model Registration] A utility model for incoming and outgoing light formed of a parallel flat optical material, with a set of parallel planes serving as reflective surfaces, and a portion of each of these reflective surfaces being coated with a non-reflective coating. An optical delay element has a window section and a reflective surface other than the window section for inputting and outputting light, which is coated with a high reflection coating, and an absorbing material is provided on the surface other than the reflective surface. a fiber connector, an optical fiber, and a self-occurring lens for incident light, which are provided on the window side of the optical delay element, and for allowing light to enter the optical delay element through the window for incident light; a self-occurring lens for output light, an optical fiber, and a fiber connector provided on the window side of the output light for condensing the light emitted from the window for the output light; a self-occurring lens driving section for synchronously rotating the self-occurring lenses for input and output light around the input and output points of the window section, respectively, and a self-occurrence lens drive section for rotating the self-occurrence lens for input and output light in synchronization with the input and output points of the window section, and the optical delay element from the window section for input light. Light is incident on the lens, is subjected to multiple reflections on the reflective surface coated with the high reflection coating, and is emitted from the window for outputting light to obtain a delayed output. The input and output points are respectively centered on the input and output points of the window for input and output light.
An optical delay device characterized in that the delay time can be varied by synchronously rotating a self-occurring lens for emitted light.
