Abstract
本发明提供一种可以对发出红外线的物体成像的影像模组。所述影像模组包括至少一个非球面透镜单元、红外线影像传感器以及允许红外线通过的红外线滤波器,所述红外线滤波器设置在影像传感器与透镜单元之间。
Description
技术领域
本发明涉及一种影像模组,尤其是一种红外线成像的影像模组。
背景技术
数码相机是一种全新的照相机,不用底片,而改一数字资料的方式,将拍摄到的影像储存到相机的存储器。当存储器储存满后,也不需要冲洗,只要将影像资料传送到电脑上,即可用影像处理软件编辑或用打印机印出。
数码相机的原理和传统相机很接近,只不过是用来感光并储存影像的底片被电子传感器和存储器取代而已,电子传感器负责接收影像,并将其转换为数字资料,而存储器则用来储存影像资料。
此外,某些数码相机除了可以如同一般相机一样,拍摄静态的影像外,还可以如同摄像机一样,拍摄动态的影像,甚至把声音也纪录下来。
一般的数码相机是采用可见光成像,夜晚或者光线弱的环境下,采用可见光成像的相机便无法使用,此时需要特殊的相机以得到所需要的影像。
发明内容
有鉴于此,有必要提供一种可以对发出红外线的物体成像的影像模组。
一种影像模组,其包括至少一个非球面透镜单元、红外线影像传感器以及允许红外线通过的红外线滤波器,所述红外线滤波器设置在影像传感器与透镜单元之间。
与现有技术相比,所述影像模组利用红外线进行成像,所以即使在夜晚或者光线弱的环境下,也可以对发出红外线的物体成像。
附图说明
图1是本发明影像模组的示意图。
图2是本发明影像模组中红外线滤波器的示意图。
具体实施方式
下面将结合附图对本发明作进一步详细说明。
如图1所示,本发明实施例提供之影像模组10包括一个镜筒11以及容纳在镜筒11中的第一透镜单元12、第一间隔体13、第二透镜单元14、第二间隔体15、红外线滤波器16、盖体18、红外线影像传感器19和容纳镜筒11的固定装置17。
镜筒11外表面具有外螺纹110,固定装置17内表面具有内螺纹170,内螺纹170与外螺纹110相配合,以使镜筒11可以在固定装置17里上下移动调整影像模组10的焦距。盖体18及影像感测器19固定在固定装置17中。
第一透镜单元12通过第一间隔体13与第二透镜单元14隔开一定距离。第一透镜单元12与第二透镜单元14均设有防反光(AR,anti-reflection coating)涂层120,该防反光涂层120可有效地减低外来光线的反射。第一透镜单元12和第二透镜单元14可以是单个非球面透镜,也可以是多个非球面透镜组成的透镜组。
第二透镜单元14通过第二间隔体15与红外线滤波器16个开一定距离。红外线滤波器16包括玻璃基板164以及设置在基板164上的薄膜叠层162。
红外线滤波器16为带通滤波器,其带宽在60纳米至200纳米之间。波长在800纳米至1100纳米之间的红外线可以通过红外线滤波器16,而可见光、波长在400纳米至800纳米的红外线以及波长在1100纳米至1200纳米之间红外线通过率小于2%。
如图2所示,红外线滤波器16的薄膜叠层162包括交替设置的若干第一膜层1621及若干第二膜层1622。第一膜层1621设置在基板164上,第二膜层1622叠加在第一膜层1621上。
第一膜层1621的材料包括二氧化硅,第二膜层1622的材料包括二氧化钛。
可选择地是,第二膜层1622设置在基板164上,第一膜层1621叠加在第二膜层1622上。
欲成像物体发出的光线依次经过第一透镜单元12、第二透镜单元13后,入射至红外线滤波器16。红外线滤波器16滤出所需要的红外线,红外线经过盖体18后,以红外线成像的方式在红外线影像传感器19上成像。
红外线影像传感器19可以为电荷耦合传感器(CCD,charge coupleddevice)或者互补金属氧化物半导体传感器(CMOS,complementary metaloxide semiconductor)。
本实施例之影像模组10利用红外线进行成像而不是可见光,因此可以对发出红外线的物体成像。
另外,本领域技术人员还可以在本发明精神内做其它变化,当然,这些依据本发明精神所做的变化,都应包含在本发明所要求保护的范围之内。
