Customized optical sensors are widely used at present, but in fact it has also experienced a long period of development. A report from a consulting company in the United States shows that in 2007, the global customized optical sensor market value was 50 billion US dollars, by 2001 its value reached nearly 61 billion US dollars, the speed of this development is very rapid. Among them, the United States, China, Japan and Canada are the regions with the largest demand. China is the fastest growing region for customized optical sensor market.

According to statistics, the application of customized optical sensors in automobiles has the fastest growth rate, followed by remote control equipment. In recent years, the technology of photoelectric sensing has developed most rapidly, and people's demand for it is also increasing, and the requirements are getting higher and higher. The customized optical sensor has developed from the initial bulky and slow type to the direction of miniaturization, intelligence and systematization.
In my country, due to the support of the state and the encouragement of the government, customized optical sensors have formed a unified process of self-development, self-production and self-application. We have achieved self-sufficiency and do not need to introduce foreign optical sensor technology. The customized optical sensor has also been basically recognized in the world, but we still need to make continuous efforts to continuously improve the technology of customized optical sensors in our country and improve the application of customized optical sensors in equipment. It is undeniable that there is still a certain gap between my country's customized optical sensors and foreign countries, so It is also necessary to continuously improve and strive to surpass foreign technology as soon as possible.
