On October 23, 2015, the 21st Annual Spectrum Conference and the National Symposium on Spectroscopic Instruments and Analytical Monitoring were held in Beijing. The theme of this conference is openness and innovation.
Chen Bin, from the School of Food and Bioengineering, Jiangsu University, reports on the development and application of miniature spectrometers and cloud services for mobile operating systems. In the report, the new requirements of the spectrum analysis technology for instruments, the development trend of miniature spectrometers, the application research based on Hamamatsu micro-spectral sensors, and the application of "Internet +" in micro spectrometers are introduced.

New requirements for instrumentation by spectral analysis techniques
The new requirements of the spectrum analysis technology for the instrument include the development and application of the combined technology, software, the development of new detection methods and accessories, the development of high (multiple, super) spectroscopy, microspectral imaging instruments, small and micro instruments. , network (cloud) service technology.
With the development of related technologies, the research and development of small and micro-spectral instruments has been put on the agenda. This is the need for on-site real-time rapid detection, emergency emergencies, market regulation, mobile inspection, and daily home, especially food quality assurance. Need, but also the need to reduce instrument costs and use costs. Chen Bin said that the spectrum instrument is made into small household appliances for sale, and the market is very impressive.
After the spectrum instrument and the analytical instrument segment, the Internet is needed. The development of instruments in recent years:
Sensor + data acquisition system + computer = virtual instrument;
Analytical instrument + computer + network = network instrument (fixed site detection);
Micro Instrument + Mobile Operation + Mobile Network = Mobile Cloud Instrument (Field Field Detection).
4 positioning can be realized by using the mobile operation platform: location (GPS, or Beidou), usage time, user (mobile number), and 4 positioning of detection content (uploading data in time). To ensure the authenticity of the data, not to give some people the opportunity to modify the data, to ensure that there is no longer the phenomenon of "migrant workers" on the data.
Trends in microspectral instruments
1. The size of the instrument is getting smaller and smaller;
2. The operating system of the instrument is diversified;
3. Intelligent analysis, data sharing system networking: remote monitoring of instrument working status; instrument software update; database comparison, query, suspicious data upload; automatic download of detection model; instrument geographical location, time, data timely Upload.
Application Research Based on Hamamatsu Micro-spectral Sensor
Chen Bin also introduced the application research based on Hamamatsu miniature spectrum sensor. The C11708MA miniature spectrometer manufactured by Hamamatsu has a compact structure, the size of the thumb is only 9g, and the spectral response range is 640nm-1050nm. Chen Bin introduced the research based on the C11708MA miniature spectrometer, such as alcoholic alcohol test, sesame oil content test, chlorophyll content test.
Application of "Internet +" in miniature spectrometer
Chen Bin team has reached the joint development intention of C13272, which has the latest products, and is ready to directly develop on the mobile phone. The driver circuit plan is to achieve the chip level and truly spread to the daily life of thousands of households. in life. In recent years, the Chen Bin team has spent a lot of energy and set up team resources to carry out the establishment of a practical system based on mobile cloud-supported micro-spectral instruments. It has been extended to smartphone control systems such as temperature and humidity meters, acidity meters, conductivity meters, dissolved oxygen meters, and sound analysis.
At the end of the report, Chen Bin concluded that the introduction of small and micro near-infrared spectroscopy instruments into reality has become a reality, escorting the food quality of the people; "Internet +" is calling for near-infrared spectroscopy instruments, providing information for spectroscopic instruments. New operating modes; devices are becoming more and more abundant, prices are getting lower and lower, and performance is getting better and better; now we are still making wedding dresses for others. When can I have core components made in China?
