Title:
LASER TRANSMISSION CIRCUIT, LASER TRANSMISSION ASSEMBLY, AND ELECTRONIC MEASUREMENT INSTRUMENT
Document Type and Number:
WIPO Patent Application WO/2024/000737
Kind Code:
A1
Abstract:
Disclosed in the present application are a laser transmission circuit, a laser transmission assembly, and an electronic measurement instrument. The laser transmission circuit comprises: an analog transmission unit, which is used for converting an accessed input analog signal into a corresponding analog laser signal and then transmitting the analog laser signal; an analog receiving unit, which is used for converting the analog laser signal into an analog electrical signal and then using the analog electrical signal as an output signal of the laser transmission circuit; and a digital feedback path, an input end of which is connected to an output end of the analog receiving unit, and an output end of which is connected to a feedback input end of the analog transmission unit, wherein the digital feedback path is used for accessing an analog electrical signal, which is output by the analog receiving unit, and the digital feedback path is used for converting the accessed analog electrical signal into a corresponding digital signal and then transmitting the digital signal; and the digital feedback path is further used for converting the transmitted digital signal into a corresponding low-frequency analog signal and outputting the low-frequency analog signal to the feedback input end of the analog transmission unit. By means of the present application, an error, which is caused by a laser signal to an analog signal during transmission, can be removed.
