Today I will share with you the knowledge of ultrafast spectroscopy, which will also explain the principle of ultrafast spectroscopy technology. If it happens to solve the problems you are facing now, don’t Forgot to follow this site, start now! List of contents of this article: 1. What is the performance of the hyperspectrometer? 2. What is the near infrared spectrometer? 3. Employment prospects and treatment of ultrafast spectroscopy 4. The purpose of spatial encoding of dynamic scenes by hyperspectral compression and ultrafast imaging And how about the performance of the stable phase change ultra-spectrometer? It is a high-performance instrument ultra-fast spectrum, in addition to a very high signal-to-noise ratio (snr) and all spectral channels can work at the same time ultra-fast spectroscopy, it also has GPS positioning data Ultra-fast spectroscopy, precise radiometric calibration can be carried to provide high-quality pictures. The instrument is close to the development of ultrafast spectroscopy, which can be adapted to use on multiple platforms. The hyperspectral imager developed by the famous American trw company is code-named trwis-3, and it is the latest imaging spectrometer of the company. Super power. 40KV, 100MA up to 4W high-power X-ray tube technology makes the instrument have a lower detection limit. Intelligent beam technology can achieve Ti and V accuracy up to 0.02%, and can distinguish 304 and 321, P91 and 9 chrome, 7th grade titanium and pure titanium very well. Stable working performance The professional spectrometer adopts ultra-fast spectroscopy and a highly integrated acquisition and control system, which has a high degree of automation and a low failure rate, and its working performance is also extremely stable. What is a near-infrared spectrometer? The near-infrared spectrometer is an indoor spectral analysis instrument, which uses the raster scanning method to obtain the high-resolution reflection spectrum of the target near-infrared band. Near-infrared spectrometer is a kind of spectrometer. Gaolitong spectrometer is divided into visible spectrometer, ultraviolet spectrometer, and near-infrared spectrometer. Each spectrometer has its own characteristics. Near-infrared spectroscopy mainly reflects the information of chemical bonds such as CH, OH, NH, SH, etc., so the analysis range can cover almost all organic compounds and mixtures. The Fourier transform near-infrared spectrometer has high resolution and scanning speed. The weakness of this type of instrument is also that there are moving parts in the interferometer, and it requires a stricter working environment. Ultrafast Spectroscopy job prospects are poorly paid. As of October 18, 2022, ultrafast spectroscopy, ultrafast optical physics is a relatively unpopular professional ultrafast spectroscopy, which requires relatively few talents, which means that it is more difficult to learn, so the employment prospects are not very good. It can be said that the graduation remuneration of master students in optoelectronic engineering is very good. Generally, the monthly salary can reach 20,000 yuan when you first graduate, and the salary will be even higher later. The treatment is very good, and the comprehensive income starts from 200,000 yuan a year. Salary for graduate students majoring in optoelectronics: the salary for fresh graduates is 3000-6000 yuan/month. Employment prospects are good. Employment in ultrafast electronics is still relatively good. The employment prospect of this major is good. Students can engage in research and development of computer hardware or IT products, computer management and application departments can engage in computer software development, and use computers as the main tool to engage in art design or tool research. The purpose of hyperspectral compression ultrafast imaging is to spatially encode dynamic scenes. The purpose is to make the high light part of a photo not expose the ultrafast spectrum, and the details of the dark part can retain the ultrafast spectrum. This is HDR technology; usually, you can Set the dynamic optimization as standard, and only set the dynamic optimization to advanced for scenes where the dark part is extremely dark and the bright part is extremely bright. The technique can capture highly dynamic scenes on picosecond and femtosecond timescales. The researchers point out that ultrafast multidimensional optical imaging can be applied to the detection of extremely fast phenomena in physics, chemistry and biology. The Moderate Resolution Imaging Spectrometer (CMODIS) developed by the Shanghai Institute of Technical Physics, Chinese Academy of Sciences was launched in 2002 with the "Shenzhou" III, and successfully obtained aerospace hyperspectral images, which acquired images in 30 bands from visible light to near-infrared , four bands from mid-infrared to far-infrared, with a spatial resolution of 500 m. Hyperspectral imaging technology combines optical imaging and spectral analysis, and has played an important role in remote sensing observation of plant phenology. With the development of hyperspectral imaging technology, micro-sized LCTF hyperspectral imaging technology with high spatial resolution and hyperspectral resolution capabilities is becoming more and more mature. How to improve the level of testing technology and quickly and effectively test the quality and safety of fruits and vegetables has become the main demand of the food testing market. Especially in recent years, the development of non-destructive testing technology is getting faster and faster, and hyperspectral imaging technology has become a research hotspot in the field of food and agricultural product testing. Compared with foreign countries, there is a big gap in the development of spaceborne hyperspectral imaging technology in China. Research on the development trend of ultra-fast and ultra-intense laser and its scientific application Ultra-intense laser can also provide a new solution of "laser proton knife" for the treatment of cancer Protons can be accelerated to the required energy in the centimeter range, which is currently in the experimental stage. Laser rapid prototyping technology is undergoing tremendous changes in ultrafast spectroscopy, mainly reflected in new technologies, new processes, and information networking. On some basis, broaden the application of laser rapid prototyping technology, and carry out the exploration of new molding process. Ultrafast laser industry prospect prediction Laser is the core component of laser processing equipment, and the technical level of lasers has become a key factor affecting the technical level of laser processing equipment. With the trend of power development, the application scenarios of micromachining will be further expanded. For example, laser therapy is now a common treatment modality used to treat heart disease, skin problems and cancer, among others. Scientists and military experts will continue to conduct extensive research and testing on the application and development of laser weapon technology. Induction of multilevel and stable phase transitions in Ta2NiSe5 using ultrafast laser According to 2D Semiconductors, Ta2NiSe5 is a semimetal that undergoes an exciton-insulator transition at a temperature of 330 Kelvin (57 C or 134 F). This concludes the introduction of ultrafast spectroscopy and the principles of ultrafast spectroscopy technology. Have you found the information you need?
