ABS-25 is a kind of airborne sensor specially developed for measuring the atmospheric parameters such as temperature, humidity, pressure, carbon dioxide, ozone and other aerosols. It is widely used in meteorological monitoring, airborne measurement, maritime navigation, aviation medicine, middle-atmospheric observation, etc. This article mainly introduces the application field and working principle of ABS-25.

1. Application Field of ABS-25

ABS-25 can measure the atmospheric parameters including absolute temperature, humidity, pressure, etc. It can also measure the presence of aerosols such as ozone and other components. It has a multi-functional design and is suitable for both airborne and surface observation platforms. It can be used in the following application fields:

• Meteorological Monitoring: ABS-25 can be used to monitor the atmospheric parameters in a local region, to provide weather forecasts and warning information, and to support weather operations such as flight patterns and entry routes.
• Airborne Measurement: ABS-25 can be used for the observation of atmospheric parameters in low-altitude regions, and for the monitoring of aircraft health and safety in the air.
• Maritime Navigation: ABS-25 can be used to measure the atmospheric parameters such as temperature, pressure and humidity for navigation purposes, and to provide warning information for vessel safety.
• Aviation Medicine: ABS-25 can be used by doctors to measure the atmospheric parameters such as temperature, pressure and humidity in order to assess the effects of high altitude on human health.
• Middle-Atmospheric Observation: ABS-25 can be used to measure the atmospheric parameters of the middle-atmospheric regions and to provide data for the study of climate change and other scientific phenomena.

2. Working Principle of ABS-25

The working principle of ABS-25 is based on the absorption spectroscopy. First, a source of light is used to illuminate the sample. Then, the sample absorbs certain light of particular wavelengths, resulting in a decrease in the overall intensity of the light, or the “transmission”. Finally, the intensity of the light after passing through the sample is measured and compared to the original intensity, allowing the atmospheric parameters to be calculated.

ABS-25 utilizes an electronic scanning spectrometer, which consists of three parts: an optical system, an electronics system and a data processor. The optical system consists of an optical source, which can be either a light-emitting diode (LED) or a laser diode, and a detector to measure the light intensity. The electronics system consists of an amplifier and a digital-to-analog converter (DAC) for measuring and digitizing the signal. Finally, the data processor processes the data and calculates the atmospheric parameters.

In summary, ABS-25 is a versatile airborne sensor that can measure the atmospheric parameters such as temperature, humidity, pressure and carbon dioxide. Its multi-functional design makes it suitable for a wide range of applications, such as meteorological monitoring, airborne measurement, maritime navigation, aviation medicine, and middle-atmospheric observation. It utilizes the absorption spectroscopy to measure the intensity of the light after passing through the sample, and an electronic scanning spectrometer to convert the signal into usable data. Thus, this sensor will continue to be an invaluable tool for monitoring the atmospheric environment in the years to come.
