Embodiment Construction

[0034] A wide-band, high-resolution and large-dynamic-range delay compensation system. By using the accuracy and dynamic range coverage between different components and the connection of the working bandwidth, the delay compensation is greatly expanded while ensuring wide bandwidth and high resolution. The dynamic range achieves a delay compensation effect that cannot be achieved by a single component, and at the same time improves the compatibility of the system.

[0035] Among them, the delay compensation system specifically includes a half-wave plate, electro-optic phase modulator, total reflection mirror, piezoelectric ceramics, stepping motor, signal splitter conversion module, when the model task requirement is specifically the emission of the pulse sequence to be compensated When the end coincides with the incident end and the polarization direction is the same:

[0036] Half-wave plate: adjust the polarization direction of the incident optical pulse signal to be consistent ...

Abstract

The invention discloses a broadband high-resolution large dynamic range delay compensation system and a broadband high-resolution large dynamic range delay compensation method, which utilize a plurality of optical path adjusting devices and a corresponding multi-layer control mechanism to effectively connect measuring ranges and resolution of different devices to achieve the high-speed, high-resolution and large dynamic range delay compensation mechanism, effectively alleviate the contradiction among bandwidth, resolution and dynamic range of individual devices, make full use of the cohesive relation between coverage of precision and dynamic ranges of different devices and the operating bandwidth, greatly expand the range of delay compensation while ensuring wide bandwidth and high resolution, achieve the delay compensation effect that cannot be realized by means of one device, and effectively improve the compatibility of the system.

Description

Technical field [0001] The invention relates to a wideband, high resolution and large dynamic range delay compensation system and method, and belongs to the field of laser technology. Background technique [0002] In recent years, high-stability clock distribution technology based on low-noise light sources has gradually become a new research focus. Compared with the traditional microwave signal, femtosecond (fs, 10 -15 s) The ultrashort pulse sequence output by the laser has the characteristics of narrow pulse width, wide spectrum range, and low time jitter. Using it as the carrier of the clock signal can realize the precision and lossless transmission of optical frequency signals and radio frequency signals at the same time, which is to achieve high stability Ideal signal source for clock distribution. In order to further improve the overall stability of the clock distribution system, it is necessary to further compensate the time noise introduced by various factors such as pu...
