6、组成部分，它在各领域都得到广泛的应用,并且抗干扰能力强。研究红外辐射的产生、传播、转化、测量及其应用的技术科学。任何物体的红外辐射包括介于可见光与微波之间的电磁波段。通常人们又把红外辐射称为红外光、红外线。实际上其波段是指其波长约在0.75微米到1000微米的电磁波。通常人们将其划分为近、中、远红外三部分。近红外指波长为0.753.0微米；中红外指波长为3.020微米；远红外则指波长为201000微米。在光谱学中，波段的划分方法尚不统一，也有人将0.753.0微米、3.040微米和401000微米作为近红外、中红外和远红外波段。另外，由于大气对红外辐射的吸收，只留下三个重要的窗口区，即13微米

7、、35微米和813微米可让红外辐射通过，因而在军事应用上，又分别将这三个波段称为近红外、中红外和远红外。813微米还称为热波段。红外技术的内容包含四个主要部分：(1)红外辐射的性质，其中有受热物体所发射的辐射在光谱、强度和方向的分布；辐射在媒质中的传播特性-反射、折射、衍射和散射；热电效应和光电效应等。(2)红外元件、部件的研制，包括辐射源、微型制冷器、红外窗口材料和滤光电等。(3)把各种红外元、部件构成系统的光学、电子学和精密机械。(4)红外技术在军事上和国民经济中的应用。由此可见，红外技术的研究涉及的范围相当广泛，既有目标的红外辐射特性，背景特性，又有红外元、部件及系统；既有材料问题，又有

8、应用问题。1.2 红外技术的概况自从1800年英国天文学家FW赫歇尔发现红外辐射至今，红外技术的发展经历了将近两个世纪。从那时开始，红外辐射和红外元件、部件的科学研究逐步发展，但发展比较缓慢，直到1940年前后才真正出现现代的红外技术。目前，美国将红外技术应用于单兵装备、装甲车辆、航空和航天的侦察监视、预警、跟踪以及武器制导等各个领域。红外技术2发展的先导是红外探测器的发展。1800年，FW赫歇尔发现红外辐射时使用的是水银温度计，这是最原始的热敏型红外探测器。1830年以后，相继研制出温差电偶的热敏探测器、测辐射热计等。在1940年以前，研制成的红外探测器主要是热敏型探测器。19世纪，科学家们

9、使用热敏型红外探测器，认识了红外辐射的特性及其规律，证明了红外线与可见光具有相同的物理性质，遵守相同的规律。它们都是电磁波之一，具有波动性，其传播速度都是光速、波长是它们的特征参数并可以测量。20世纪初开始，测量了大量的有机物质和无机物质的吸收、发射和反射光谱，证明了红外技术在物质分析中的价值。30年代，首次出现红外光谱代，以后，它发展成在物质分析中不可缺少的仪器。40年代初，光电型红外探测器问世，以硫化铅红外探测器为代表的这类探测器，其性能优良、结构牢靠。50年代，半导体物理学的迅速发展，使光电型红外探测器得到新的推动。到60年初期，对于13、35和813微米三个重要的大气窗口都有了性能优良

10、的红外探测器。在同一时期内，固体物理、光学、电子学、精密机械和微型致冷器等方面的发展，使红外技术在军、民两用方面都得到了广泛的应用。在红外技术的发展中，需要特别指出的是：60年代激光的出现极大地影响了红外技术的发展，很多重要的激光器件都在红外波段，其相干性便于移用电子技术中的外差接收技术，使雷达和通信都可以在红外波段实现，并可获得更高的分辨率和更大的信息容量。在此之前，红外技术仅仅能探测非相干红外辐射，外差接收技术用于红外探测，使探测性能比功率探测高好几个数量级。另外，由于这类应用的需要，促使出现新的探测器件和新的辐射传输方式，推动红外技术向更先进的方向发展。1.3 发现的问题及相关解决方案在

11、家庭，商店，以及各大娱乐场所，迎宾器的用途已经越来越广泛，客人一来，就会发出“欢迎光临”的声音，给顾客一个亲切、温馨的感觉，同时减轻了人员的劳动强度，提高顾客兴趣。所以可以说它应用的范围十分广泛，而且用途大。然而，到目前为止，迎宾器都是靠光控来实现的比较多，而且功能单一，只能说一种语音，客人来了，是“欢迎光临”，然后顾客走了仍然是“欢迎光临”，而不是“谢谢惠顾”，没有智能化，这些都已经越来越限制了它的发展。如何能够在客人来的时候会发出“欢迎光临”，客人走之后发出“谢谢惠顾”是我们现在研究的重点方向之一。随着红外技术的成熟发展，我想到了利用红外线的方法。我们知道，在常规的环境参数中，人体探测常容

12、易受环境的影响而使得参数改变，随着红外线及激光技术的成熟，许多运用于室外场合的红外线产品开始出现，由于光线是沿着直线传播的，在发射端发射出的光束，中间如果没有东西遮挡，那么接收端就能收到正常的光束；当有人经过时，光束被挡住了，此时接收端便无法接收到光束，从而产生信号，发出声音。根据以上分析，我设计出一种利用红外线进行探测的红外迎宾系统，利用双发射与接收来探测是否是出入，采用多谐振荡器作为红外线发射器的驱动电路，驱动红外发射管，向探测区内发射红外线，接收端利用专用的红外线接收器件HS0038对发射的红外线信号进行接收，经放大电路进行信号放大及整形，以单片机作为逻辑处理器，控制语音发生电路，电路中

13、有信号锁定的功能，只能当进行判断结束之后，才能关闭。这样的设计在实际应用中有比较高的价值，可以减少人力,物力以及财力的付出，是一种价格低而实用性强的产品。1.4 相关文献1红外技术. 昆明物理研究所:1979年出版2 瞿贵荣. 期刊论文.家庭电子（爱好者）. 2005年8期3 沙占友编.集成化智能传感器原理与应用.电子工业出版社:2004年1月出版4 苏长赞.红外线与超声波遥控M.北京：人民邮电出版社:1997出版5 方佩敏编.新编传感器原理.应用.北京电子工业出版社:1994年出版6 激光与红外.2005年01期7 电子报社编.电子报2004年合订本.四川科学技术出版社: 2004年出版8
