Abstract

The invention relates to a video optical power meter, comprising a PIN detector and a signal amplification, A / D conversion and frequency identification circuit connected with the PIN detector, wherein, the A / D conversion and frequency identification circuit is connected with a single-chip microprocessor; and the single-chip microprocessor converts a digital signal into optical power with a corresponding wavelength, identifies the frequency of a light source, transforms a result into a video signal through a video signal output controller (an NTSC or PAL system) and then outputs the video signal by a video interface. The video optical power meter has the beneficial effects of high running speed, strong operating capabilities, multiple measuring wavelengths and high precision.

Description

technical field [0001] The invention relates to an optical measuring instrument, in particular to an optical power measurement circuit module and a video signal output circuit module. Background technique [0002] Standing out from optical communication, optical fiber communication technology has become one of the main pillars of modern communication and plays a pivotal role in modern telecommunication networks. As an emerging technology, optical fiber communication has been developing rapidly and widely used in recent years, which is rare in the history of communication. It is also an important symbol of the world's new technology revolution and the main transmission tool for various information in the future information society. [0003] In fiber optic systems, measuring optical power is the most basic, and optical power meters must be the most commonly used measuring instruments. By measuring the absolute power of the transmitter or optical network, an optical power mete...
