Under COVID-19, there is an urgent requirement for fast and precise temperature measurement. However, the existing contact thermometers are likely to cause secondary infection, while the non-contact ones have low reliability and are easily affected by external environments.
Concerning these problems, a precise and fast optical thermometer based on tunable diode laser absorption spectroscopy is developed for breath diagnostics with relevance to non-contact body temperature measurements.
Uniqueness and Competitive Advantages:
- Non-contact measurement
- Fast response (1s real-time)
- High accuracy (< 0.16 ℃ error)
- Active measurement without needs for pre-calibration
- Highly integrated system and intelligent data post-processing program
