Huazhong University of Science and Technology majoring in optical engineering is good. According to relevant data, graduate students majoring in optical engineering are generally employed in scientific research institutes, universities, optical communication units and photoelectric instrument production units. There are many scientific research institutes and relatively few enterprises. The application of optical engineering is a large system, and a single technology can't drive the whole project, so the learning task is also a concrete one in the master's stage. In fact, energy and ability can only be deeply cultivated in one field, which limits the future employment direction. Generally, it is necessary to lay a good foundation in the undergraduate stage, such as knowledge and application of machinery, computer, electronics and circuits. Finally, with the modulation and processing of optical information signal, the project can work normally. The more you study optical engineering, the more specialized you become, and the narrower you study, the same will be true for your employment, unless you switch to machinery, electronics and electricity in the future. Of course, there are also optical engineering counterparts, generally scientific research institutes, universities, optical communication units, photoelectric instrument production units and so on.
