How does the temperature measurement accuracy of thermal imaging scopes affect their performance?

(1) Target identification accuracy

Distinguishing target types: In military and law enforcement scenarios, accurate temperature measurement accuracy helps to accurately distinguish different types of targets. For example, the temperature of the human body is usually around 36-37℃, while the temperature of parts such as the engine of a vehicle may be as high as tens of degrees Celsius or even higher. If the temperature measurement accuracy of the thermal imaging scope is high, such as being accurate to within ±2℃, it can easily distinguish personnel and equipment based on the temperature difference to avoid misjudgment.

Identifying target status: For some special targets, such as personnel hiding behind a bunker or camouflaged equipment, their temperature characteristics may be the key clue to discovering them. High-precision temperature measurement can help users determine whether the target is in normal working condition (such as whether the equipment is running hot) or whether there is abnormal heat dissipation (such as whether the human body has abnormal body temperature due to injury, carrying heating equipment, etc.).

(2) Improved shooting accuracy

Distance estimation assistance: The temperature measurement accuracy of thermal imaging scopes will affect the accuracy of distance estimation. When the actual temperature of the target and the ambient temperature are known, the apparent temperature of the target can be measured by a thermal imaging scope, and the distance of the target can be estimated by combining the atmospheric transmission model and the law of thermal radiation. If the temperature measurement accuracy is poor, the distance estimation will produce a large error, which will affect the shooting accuracy. For example, in hunting, accurate distance estimation is crucial for choosing the right shooting method and ammunition.

Environmental factors: Factors such as ambient temperature, humidity and wind speed will affect the temperature measurement accuracy of thermal imaging scopes. High-precision temperature measurement can better consider these environmental factors and make more accurate corrections to the target's thermal imaging, thereby making the aiming point more accurate. When shooting at long distances, a small temperature error may cause a large deviation in the bullet landing point, and accurate temperature measurement can help reduce this deviation.

(3) Adaptability in complex environments

Performance under adverse weather conditions: In adverse weather conditions such as rain, snow, and fog, the temperature measurement accuracy of thermal imaging scopes becomes more critical. This is because these weather factors will interfere with the transmission and reception of thermal signals and reduce the image quality. If the temperature measurement accuracy is high, the thermal imaging scope can better filter out these interference factors and accurately measure the true temperature of the target, thereby maintaining good performance. For example, in foggy days, accurate measurement of the target temperature can be used to distinguish between real targets and false targets caused by fog droplet reflections.

Dealing with thermal background interference: When the target is in a complex thermal background environment, such as near a high-temperature heat source (such as a burning building, an industrial furnace) or in terrain with large differences in thermal radiation (such as a desert or snow), high-precision temperature measurement can help users distinguish the temperature difference between the target and the background. This makes the target still clearly identifiable under complex thermal backgrounds, improving the ability of thermal imaging scopes to work in complex environments.

(4) Effective use of equipment functions

Alarm function accuracy: Some thermal imaging scopes have a temperature alarm function that sounds an alarm when the target temperature exceeds the set range. Accurate temperature measurement accuracy is a prerequisite for ensuring the accuracy and effectiveness of the alarm function. If the temperature measurement accuracy is insufficient, it may cause false alarms or missed alarms, affecting the normal functioning of the equipment. For example, in security monitoring, targets within a specific temperature range need to be monitored, and inaccurate temperature measurement may cause the monitoring system to fail.

Working in conjunction with other systems: In some complex military or industrial application scenarios, thermal imaging sights may need to work in conjunction with other systems (such as fire control systems and automated monitoring systems). Accurate temperature measurement data is an important basis for these systems to make accurate decisions. If the temperature measurement accuracy is poor, it will affect the synergy of the entire system and reduce work efficiency and safety.
