Optical engineering is a good software for employment;
1. Image processing. This is because the computer major also has this direction, so the employment is wide but the competitiveness depends on the individual. If you do image recognition or something, you can sign Baidu or something.
2. Virtual reality and reality enhancement. This is the general direction of the future. Personally, I am optimistic. You can download Zuckerberg's reality enhancement.
3. Iris recognition. Compared with fingerprint identification, it is more confidential, because fingerprints can still be changed, so let alone iris, at least at present, it cannot be changed, but there is no market yet.
Hardware:
1. If electricity-related employment is not bad. For example, the circuits used for imaging are now embedded with FPGA and DSP, which have wider applications.
2. Laser. There are few applications themselves, but because of the unpopularity, fewer people are recruited and fewer people are enrolled. Usually companies directly recruit people because they have no choice.
3. Optical design. Due to the limited level of precision machining in China, most of them went to research institutes, and Changguang Institute was very good.
4. Optical fiber and communication. This is not clear, welcome to add.
Why do you say that optical engineering is the main reason for quitting your major is that you can't find a job. Why can't you find a job? Actually, it's a very simple thing. As far as the lens is concerned, what is most needed is optical design. And you have been engaged in the interaction between two-dimensional materials and light during your master's degree. Even if you have made advanced materials, you may not have started zemax yet. It is far from easy to do optical design during the master's degree. Of course, this is only a small aspect. Some people say that you can teach yourself. If the education and training of this subject can't meet the market demand, it doesn't feel appropriate to ask students to study by themselves. Moreover, this optical design is quite experienced, and I personally feel it is necessary to deal with it.
You will find that the most interesting thing is the gap in the professional direction of the company in this industry, which may be the research direction of the research group that your school is the least able to help you get this professional scholarship ... In fact, as far as employment is concerned, the master may not have to do research with the tutor ... I think it is necessary to strengthen the curriculum design, for example, let the teachers engaged in optical design teaching take students to participate in the course study, and divide them into several groups to do some industry-related projects, so that students can write something that is easily valued by the company on their resumes.
