紅外傳感器從軍事發(fā)展到物聯(lián)網(wǎng)應(yīng)用

　　使用紅外傳感器準(zhǔn)確地測(cè)量材料或氣體在軍事應(yīng)用中的化學(xué)成分是眾所周知的?，F(xiàn)在，然而，他們迅速下降的價(jià)格標(biāo)簽，這些紅外傳感器是物聯(lián)網(wǎng)M2M應(yīng)用互聯(lián)網(wǎng)獲得牽引力，包括醫(yī)療診斷、成像、工業(yè)過程控制、火災(zāi)探測(cè)和遠(yuǎn)程煤氣泄漏檢測(cè)、污染監(jiān)測(cè)、實(shí)時(shí)燃燒控制。

　　有三個(gè)主要的波長(zhǎng)/頻率類別的紅外光譜：近，中，遠(yuǎn)紅外。近紅外涉及光纖，紅外傳感器在700 nm–1400 nm（0-7μM–1.4μm）范圍。中紅外包括在1400 nm 3000 nm–熱傳感裝置（1.4μM–3μm）范圍內(nèi)，或遠(yuǎn)，或熱紅外成像，包括3000 nm–1毫米（3μM–1000μm）；所有的市場(chǎng)都在銷售和產(chǎn)品開發(fā)的上升。

　　According to a recent market research report by ReportsnReports，1 mid-IR sensor markets totaled $789 million in 2012 and are forecast to reach $7 billion by 2019. The impetus for growth includes price-performance increases and unit cost decreases from a high of $3，000 per unit to $300， in some cases， all the way down to approximately $8 per unit. Size has also migrated from bench sizes to portable units.

　　A WinterGreen Research study， Mid-IR Sensor： Market Share， Strategy and Forecasts， Worldwide， 2013 to 2019，2 focuses on how sensors are becoming part of network systems in the IoT， fueling substantial demand. What is new is the use of new types of lasers for a wide array of sensing applications， from industrial process controls and environmental monitors to new medical diagnostics.
