In 2016, the total defense expenditure of countries in the Asia-Pacific region reached $450 billion, and five of the world's top 10 military powers came from the Asia-Pacific region, of which China accounted for about 42 percent of the region's military expenditure. According to the fact that military infrared detection in the Asia-Pacific region accounts for 21 percent of the global market, China's military infrared detection market in 2016 is roughly calculated to be about $640 million, accounting for about 0.33 percent of total military expenditure. There is still a big gap between China's military infrared detection market and the United States, and penetration needs to be improved.
According to the YoleDeveloppementGroup statistics, the proportion of thermal imaging, infrared monitoring and fire protection applications in the global uncooled infrared thermal imager market is 24%,14% and 13%, respectively, accounting for more than half of the total uncooled infrared market.At present, the domestic civil infrared detector is mainly hand-held thermal imager, and its application in monitoring, fire protection and other fields needs to be expanded.At the same time, in some emerging applications such as smart phone thermal imaging accessories account for 5% of the global market share, but in the domestic popularity and application is low.
According to the statistics of YoleDeveloppementGroup, the cost of assembly, test and calibration is the largest, accounting for 43.9% of the total cost, followed by infrared detector, accounting for 24.9% of the total cost.
The cost reduction of infrared imager is mainly through three ways :1, using wafer level technology to produce detector, and enjoying the cost reduction caused by scale effect through mass production. 2. reduce sensor chip size, that is, reduce pixel spacing size. The 12μm pixel structure is being actively promoted by all microthermometer manufacturers to increase the sensor's thermal sensitivity to 50 mK. 3. the production of uncooled infrared sensors that are more suitable for low cost and low pixels, as the low-end market expands, the pixel resolution requirements of the sensors are reduced, so the commercial opportunities for low-resolution sensors will increase.With the breakthrough of domestic infrared detector technology, the cost of infrared thermal imager will be further reduced. We predict that infrared detection will likely increase rapidly in civil field in the future.
