Abstract

The embodiment of the invention provides an all-optical two-dimensional quantization and coding method, an all-optical two-dimensional quantization and coding system and electronic equipment. The method comprises the steps of: on the basis of any obtained corresponding optical signal, obtaining the first code corresponding to any optical signal through multiple judgment thresholds by any amplitudequantization module, wherein any optical signal is obtained through a multichannel array filter; and, on the basis of first codes corresponding to all optical signals obtained by all the amplitude quantization module, obtaining second codes, so that all-optical two-dimensional quantization and coding are completed. According to the all-optical two-dimensional quantization and coding method, the all-optical two-dimensional quantization and coding system and the electronic equipment provided in the embodiment of the invention, the first code corresponding to any optical signal is obtained through multiple judgment thresholds; the problem that the position of the central wavelength only can be roughly estimated by adoption of single judgement in the prior art can be avoided; the false code condition can be avoided by adoption of the multiple judgment thresholds; and thus, the finally obtained second codes are relatively accurate.

Description

Technical field [0001] The embodiments of the present invention relate to the field of analog-to-digital conversion, and in particular to a method, system and electronic device for all-optical two-dimensional quantization and coding. Background technique [0002] Naturally existing signals are all analog signals, and the purpose of analog-to-digital conversion is to convert natural signals into digital signals that can be recognized by general computing platforms. The purpose of all-optical analog-to-digital conversion instead of electrical analog-to-digital conversion is to overcome the problem of operating frequency limit caused by electronic bottlenecks. The measurement and analysis of high-frequency analog signals and the demand for analog-to-digital conversion of high-speed ultra-wideband communication equipment has exceeded the GS / s (Giga Sample Per-second) level and is still increasing day by day. It is still difficult to overcome the physical limit to obtain higher perfo...
