本发明涉及安检技术领域，尤其涉及一种毫米波三维全息扫描成像设备。
背景技术
面对日益严峻的公共安全形势，实现快速有效的人体安全检查开始成为机场、地铁站等人流密集场所亟待解决的问题。目前机场的人体安检主要依靠安检员手持金属探测器对乘客进行全身扫描，该方案只对金属物品有效并且无法对隐私部位进行检查。人体安检设备主要包含X射线背散射人体成像设备和毫米波人体成像设备。X射线背散射人体成像设备利用X射线入射到人体表面散射回来的信号进行成像，由于X射线具有致电离性，其在安全性方面易受到公众质疑。毫米波人体成像设备主要包含主动式和被动式两种。主动毫米波成像的图像质量明显优于被动式成像，良好的成像效果保证了对违禁品的高识别率，因此主动式毫米波人体安检设备已经逐渐成为人体安检设备的主流发展方向。而主动式毫米波成像技术又以全息成像技术为主。
运用于人体安检的主动式毫米波三维全息成像技术中，柱面扫描成像技术运用较为广泛，但其设备占地面积大且难以对待测对象的四周进行完整的成像。

具体实施方式
下面通过实施例，并结合附图，对本发明的技术方案作进一步具体的说明。在说明书中，相同或相似的附图标号表示相同或相似的部件。下述参照附图对本发明实施方式的说明旨在对本发明的总体发明构思进行解释，而不应当理解为对本发明的一种限制。
根据本发明的总体构思，提供一种毫米波三维全息扫描成像设备，包括：至少一个毫米波收发机以及与所述至少一个毫米波收发机对应地电连接的至少一个毫米波收发天线阵列，所述至少一个毫米波收发天线阵列分别用于发送和接收至少一个毫米波信号；至少一个引导装置，所述至少一个毫米波收发天线阵列分别对应连接至所述至少一个引导装置从而能够随所述至少一个引导装置移动以对待测对象的周侧进行扫描，所述至少一个毫米波收发天线阵列的延伸方向分别与所述至少一个引导装置垂直；驱动装置，用于驱动所述至少一个引导装置移动以带动所述至少一个毫米波收发天线阵列以沿直线形轨迹进行扫描；和壳体，所述壳体包围待测对象在检测时所处的检测 区域，所述壳体形成有供待测对象进入检测区域的入口和供待测对象离开检测区域的出口。
另外，在下面的详细描述中，为便于解释，阐述了许多具体的细节以提供对本披露实施例的全面理解。然而明显地，一个或更多个实施例在没有这些具体细节的情况下也可以被实施。
图1示意性地示出根据本发明的一实施例的毫米波三维全息扫描成像设备100。该毫米波三维全息扫描成像设备100可以包括：毫米波收发机10以及与所述毫米波收发机10对应地电连接的毫米波收发天线阵列20，所述毫米波收发天线阵列20用于发送和接收毫米波信号；引导装置30，毫米波收发天线阵列20连接至引导装置30从而能够随所述引导装置30移动以对待测对象90的周侧进行扫描，毫米波收发天线阵列20的延伸方向与引导装置30垂直；驱动装置40(例如驱动轮及其电机等)，用于驱动引导装置30移动以带动毫米波收发天线阵列20以沿直线形轨迹进行扫描；和壳体50，所述壳体50包围待测对象90在检测时所处的检测区域91，所述壳体50形成有供待测对象90进入检测区域91的入口92和供待测对象90离开检测区域91的出口93。作为示例，壳体50可以具有圆筒形状。作为示例，毫米波收发天线阵列20可以位于壳体50内侧、外侧或壳体50中。
根据本发明的实施例的毫米波三维全息扫描成像设备采用了具有独立的入口92和出口93的结构，待测对象(例如人员或物品)可以方便地在检查之前从入口92进入，而在检查之后从出口93走出。这与仅具有一个出入口的传统检查设备相比，待测对象无需转身就可以进入和离开检测区域，提高了检查效率。这对于机场、车站等人流密集的场所的安全检查尤其有利。
在一示例中，如图1所示，毫米波收发天线阵列20的扫描方向为竖直方向，且毫米波收发天线阵列20沿着水平方向延伸。这种设置有助于方便地实现对于待测对象周侧的扫描。在图1的示例中，毫米波收发天线阵列20具有圆环形状。该圆环形状的毫米波收发天线阵列20完整地围绕待测对象，只需要进行一次从上至下(或从下至上)的扫描就可以完成对于待测对象的所有侧面的毫米波数据进行采集，从而实现全视角的毫米波全息成像。这种方式操作简单，操控便利。然而，本领域技术人员应当理解，虽然在上述示例中采用了一个圆环形状的毫米波收发天线阵列20，但是本发明的实施例不限于此，也可以使用更多个毫米波收发天线阵列20来实现扫描，例如可以将该圆环形状的毫米波收发天线阵列20在圆周方向上分成多个独立的圆弧形状的毫米波收发天线阵列20，同样可以完成对待测对象的扫描。采用多个毫米波收发天线阵列20，可以减轻单个毫米波收发天线阵列20的重量，提高操作的灵活性。
作为示例，入口92和出口93分别位于所述检测区域91的两侧，如图1-2所示。这有助于提高待测对象通过检测区域91的效率，尤其是在待测对象需要排队检测时。
在一示例中，毫米波三维全息扫描成像设备100还可以包括：设置于入口92处的第一门装置51和设置于出口93处的第二门装置52。所述第一门装置51和第二门装置52配置成在所述毫米波收发天线阵列20进行扫描时关闭而在毫米波收发天线阵列20进行扫描之前或之后打开。第一门装置51和第二门装置52能够在毫米波收发天线阵列20进行扫描时为检测区域91提供一个封闭的环境。对于毫米波收发天线阵列20在扫描过程中经过入口92和出口93位置的情况，第一门装置51和第二门装置52可以防止毫米波收发天线阵列20在扫描过程中暴露给待测对象90以避免发生危险或对待测对象90产生不利影响。而在扫描结束后，毫米波收发天线阵列20可以隐藏于壳体50的顶端或底端，而不妨碍待测对象90从入口92或出口93通过。
作为示例，第一门装置51和第二门装置52中的每个可以具有第一壁53和第二壁54，所述毫米波收发天线阵列20能够从所述第一壁53和第二壁54之间扫描通过。这可以避免毫米波收发天线阵列20暴露给待测对象或毫米波三维全息扫描成像设备外部的人员，以避免意外。类似地，壳体50也可以采用与第一门装置51和第二门装置52类似的双层壁结构，以将毫米波收发天线阵列20容纳于双层壁之间。
在一示例中，第一壁53相对于第二壁54更靠近所述检测区域91，所述第一壁53对于毫米波信号至少是部分透明的，例如是完全透明的。这可以保证毫米波收发天线阵列20对于毫米波信号的顺利收发。作为示例，第二壁54可以对于毫米波信号具有屏蔽作用，以防止毫米波信号对于周围环境产生干扰。作为示例，所述第一门装置51和第二门装置52可以是圆弧形的自动门。
在一示例中，该毫米波三维全息扫描成像设备100还可以包括数据处理装置70。数据处理装置70与毫米波收发机无线连接或有线连接以接收来自毫米波收发机的对于待测对象的各个侧面的扫描数据并生成毫米波全息图像。该毫米波三维全息扫描成像设备100还可以包括显示装置80。显示装置80与数据处理装置70相连接，用于接收和显示来自数据处理装置70的毫米波全息图像。
在一示例中，数据处理装置70可以用于控制驱动装置40以驱动毫米波收发天线阵列20运动。在另一示例中，毫米波三维全息扫描成像设备100也可以包括与所述数据处理装置70相独立的控制装置71。
作为示例，驱动装置40可以包括驱动轮41-42，其可以在驱动轴和驱动电机的驱动下旋转。还可以根据需要设置一些从动轮43、44。虽然图1中示出了两个驱动轮41-42和两个从动轮43、44，但在本发明的实施例中，驱动轮和从动轮的数量不限于此，也可以采用一个、两个、三个或多于四个驱动轮或从动轮。在采用多个驱动轮的情况下，这些驱动轮可以独立地工作，也可以一起协作。
作为示例，所述引导装置30可以包括与所述驱动轮41-42啮合的传动带索，例如皮带、缆索等本领域已知的能够用于实现上述传动功能的部件。
作为示例，所述毫米波收发天线阵列20可以通过固定装置35、36固定于引导装置30。该固定装置35、36可以包括滑座、卡件等等。
图2示出根据另一实施例的毫米波三维全息扫描成像设备100’。在该毫米波三维全息扫描成像设备100’中，设有第一毫米波收发天线阵列21和第二毫米波收发天线阵列22，所述第一毫米波收发天线阵列21用于发送和接收第一毫米波信号，所述第二毫米波收发天线阵列22用于发送和接收第二毫米波信号。相应地，该毫米波三维全息扫描成像设备100’还设有第一引导装置31和第二引导装置32，所述第一毫米波收发天线阵列21连接至所述第一引导装置31从而能够随所述第一引导装置31以第一扫描轨迹移动以对待测对象90的第一侧进行扫描，所述第二毫米波收发天线阵列22连接至所述第二引导装置32从而能够随所述第二引导装置32以第二扫描轨迹移动以对所述待测对象90的第二侧进行扫描。作为示例，还可以设有与第一毫米波收发天线阵列21和第二毫米波收发天线阵列22分别对应的第一毫米波收发机11和第二毫米波收发机12。
在图2的示例中，入口91和出口92分别位于检测区域91的两侧第一毫米波收发天线阵列21和第二毫米波收发天线阵列22可以相对地布置，以便于避开入口91和出口92。在这种情况下，可以不在入口91和出口92处设置门装置。为了在对待测对象的扫描中获得尽可能大的扫描面积，第一毫米波收发天线阵列21和所述第二毫米波收发天线阵列22可以均具有圆弧形状。第一引导装置31和第二引导装置32可以是各自独立的引导装置，例如各自独立的传动带索、导轨等等，也可以由一个整体的传动带索的两个不同的部分形成，在后者的情况下，在扫描过程中，第一毫米波收发天线阵列21和第二毫米波收发天线阵列22将只能反向移动，但有利于简化驱动装置40的设计。与前述的实施例相似，第一引导装置31和第二引导装置32可以在诸如驱动轮等驱动装置来驱动。相应地，其也可以包括如前所述的数据处理装置70、显示装置80以及控制装置71等结构。采用图2所示的结构，也可以实现待测对象的快速通过和检测，且可以实现对于待测对象的周侧的大部分(除去面向入口91和出口92的部分)进行扫描。
在一示例中，传动带索在实现传动的同时，也可以为所述第一毫米波收发天线阵列21和第二毫米波收发天线阵列22的扫描运动提供一定的约束，例如，可以使所述第一毫米波收发天线阵列21和第二毫米波收发天线阵列22只能以相等的速率沿反向移动。
在另一示例中，第一毫米波收发天线阵列21和第二毫米波收发天线阵列22也可以组合形成对待测对象90的完整包围以实现对于待测对象90所有侧面的完整扫描。例如，可以将图1的示例中的圆环形状的毫米波收发天线阵列20由两个半圆环形的毫米波收发天线阵列替代。
图3示出根据另一实施例的毫米波三维全息扫描成像设备100”。在该毫米波三维全息扫描成像设备100”中，与如图2所示的毫米波三维全息扫描成像设备100’类似，也设有第一毫米波收发天线阵列21、第二毫米波收发天线阵列22、第一引导装置31、第二引导装置32、驱动装置40等。然而，在图3的示例中，第一毫米波收发天线阵列21具有圆弧形状，第二毫米波收发天线阵列22具有直线形状。相应地，如图3所示，壳体50具有半圆筒形状。
作为示例，入口92和出口93可以设置在检测区域91的同一侧。而待测对象可以借助于旋转门55从入口92进入或从出口93离开该毫米波三维全息扫描成像设备100”。该旋转门55可以具有第一旋转位置和第二旋转位置，在所述第一旋转位置，所述旋转门55关闭所述入口92和所述出口93，而在所述第二旋转位置，所述旋转门55打开所述入口92和所述出口93，所述旋转门55设置在毫米波三维全息扫描成像设备100”的第二毫米波收发天线阵列22所在的一侧。图3示出的是旋转门55关闭的位置，即第一旋转位置。而旋转门55例如从该第一旋转位置围绕旋转轴线56旋转90度，就可以打开入口92和出口93，而到达第二旋转位置。在一示例中，第二毫米波收发天线阵列22可以设置成与旋转门55一起旋转。而替代地，第二毫米波收发天线阵列22也可以在旋转门55旋转时隐藏于壳体50中位于旋转门55上方或下方的位置处，从而避免妨碍旋转门55的旋转。
对于上述示例，入口92、出口93与圆弧形状的第一毫米波收发天线阵列21和直线形状的第二毫米波收发天线阵列22可以采用多种布置方式，例如如图4-图6所示的示例性布置方式。
在图4的示例中，圆弧形状的第一毫米波收发天线阵列21和直线形状的第二毫米波收发天线阵列22组合形成封闭布置，于是，入口92和出口93需要通过旋转门55来打开和封闭。采用这种方式，扫描操作的封闭性好而且可以将毫米波三维全息扫描成像设备100”设计得更为紧凑以进一步减小占地面积。
在图5的示例中，圆弧形状的第一毫米波收发天线阵列21和直线形状的第二毫米波收发天线阵列22没有组合形成封闭布置，而是在第二毫米波收发天线阵列22的两边留出入口92和出口93。这种方式可能需要较大的占地面积，但是可以避免旋转门55的使用且仍然可以实现对待测对象90的全方位扫描。
在图6的示例中，第一毫米波收发天线阵列21和第二毫米波收发天线阵列22的间距进一步拉大，在圆弧形状的第一毫米波收发天线阵列21和直线形状的第二毫米波收发天线阵列22之间留有的入口92和出口93敞开的角度更大，这种方式可以使得待测对象90的进出更为方便，可以沿直线路径进出毫米波三维全息扫描成像设备100”而不需要转弯，但这种模式可能导致待测对象90的一部分(例如与入口92和出口93相对的部分)不能被扫描到。
作为示例，上述旋转门55也可以采用与第一门装置51和第二门装置52相似的双层壁结构以在扫描进行过程中将第二毫米波收发天线阵列22容纳在双层壁之间。
对于设置有第一毫米波收发天线阵列21和第二毫米波收发天线阵列22的毫米波三维全息扫描成像设备100’、100”，作为示例，其可以设置成在扫描过程中第一毫米波收发天线阵列21和第二毫米波收发天线阵列22在大部分时间不处于相互正对的位置，以减小第一毫米波收发天线阵列21和第二毫米波收发天线阵列22之间的干扰。然而这不是必须的，例如，所述第一毫米波收发天线阵列21和第二毫米波收发天线阵列22也可以采用相同的扫描方向来进行同步的扫描。
在另一示例中，第一毫米波收发天线阵列21和第二毫米波收发天线阵列22也可以采用不同的速度进行扫描(例如，在待测对象的不同的侧面或不同的局部可能需要以不同的精细程度进行扫描的情况下)，这可以兼顾检测的准确性和效率。作为示例，毫米波收发天线阵列20、第一毫米波收发天线阵列21和第二毫米波收发天线阵列22在扫描中的速度可以是恒定的，也可以是可变的，后者可以实现变速扫描，为检测工作提供更多的灵活性。
作为示例，至少一个毫米波收发天线阵列可以设有彼此错位布置的一列发射天线和一列接收天线。例如，该列接收天线可以与该列发射天线列平行布置但在水平方向上错位半个天线尺寸。在天线阵列工作时，每一时刻只有一个发射天线和其相邻的一个接收天线工作。通过电子开关切换，可以实现水平方向的快速扫描。毫米波收发系统采用步进频率连续波的扫描方法，频率扫描范围可以为24-30GHz或27-33GHz，频率扫描点数由最大成像距离决定。
在毫米波收发天线阵列的扫描过程中，作为示例，当某一高度处的所有收发单元都工作过后，毫米波收发天线阵列移动到下一个竖直位置进行如上所述的水平方向快速扫描。由于在水平方向上一整排扫描的速度非常快，因此扫描天线阵列可以在竖直方向上以较快的速度连续运动。使用驱动电机带动驱动轮或与驱动轮连接的驱动轴转动，并通过引导装置连接天线阵列就可以实现上述运动。当两排天线阵列分别移动了整个装置竖直高度的距离后，一次扫描结束。这时待测对象可以直接从出口93离开检测区域，即完成了该次检查。
作为示例，在毫米波收发机和毫米波收发天线阵列的工作过程中，毫米波源可以产生两路毫米波信号，一路作为发射信号，通过放大器和发射天线对待测对象发出毫米波；另一路作为参考信号，与接收天线接收的毫米波信号混频，通过I/Q解调得到毫米波全息数据。作为示例，各个毫米波收发天线阵列(如第一毫米波收发天线阵列和第二毫米波收发天线阵列)可以采用相同的毫米波扫描频率。
替代地，为了减小第一毫米波收发天线阵列和第二毫米波收发天线阵列之间的信号干扰，在一示例中，第一毫米波收发天线阵列发送和接收的毫米波信号和第二毫米 波收发天线阵列发送和接收的毫米波信号可以采用不同的频率。或者，在另一示例中，在第一毫米波收发天线阵列和第二毫米波收发天线阵列一起对待测对象进行扫描的整个过程中，第一毫米波收发天线阵列和第二毫米波收发天线阵列发射毫米波的时刻不同，即不同时发射毫米波。这也可以削弱或避免第一毫米波收发天线阵列和第二毫米波收发天线阵列之间的信号干扰。
根据本发明的实施例的毫米波三维全息扫描成像设备100、100’、100”，可以减小毫米波检查系统的占地面积和提高检查效率。
虽然结合附图对本发明进行了说明，但是附图中公开的实施例旨在对本发明优选实施方式进行示例性说明，而不能理解为对本发明的一种限制。
虽然本发明总体构思的一些实施例已被显示和说明，本领域普通技术人员将理解，在不背离本总体发明构思的原则和精神的情况下，可对这些实施例做出改变，本发明的范围以权利要求和它们的等同物限定。
