Description

一种激光阵列装置及其投影机照明光路 技术领域
本发明涉及数字投影显示技术领域，更具体地说，涉及一种激光阵列装置及其投影机照明光路。
背景技术
近年来,便携式电子设备功能的提升，使得用户对人机界面的显示器件的要求越来越向着微型、大屏幕以及高分辨率方向发展。在广大用户强烈需求的促使下，投影机技术发展迅猛，DLP、LCOS等产品纷纷推出了性能高、尺寸小且重量轻的便携式的投影机。
在激光投影领域，常采用多颗激光器组成激光器阵列来作为***的光源，而每颗激光器前一般会配一颗准直透镜，用于输出准直的激光束，此时，激光器阵列可输出多束准直激光束。一般而言，为了使得多束准直激光束可以进入后续的光学***，常常需要对它们的空间尺寸做压缩处理，目前主流的方案是采用望远镜组来实现光束空间尺寸的压缩，如图1所示，图1为所述望远镜组结构方案。
采用望远镜组的方案来压缩激光束的空间尺寸，可以达到比较满意的压缩效果，但是存在以下的几个问题：望远镜组会占用较多的空间位置，包括横向和纵向的空间尺寸，特别是对于空间紧凑度要求较高的情况，采用望远镜组往往无法满足实际的使用要求，因为占用了宝贵的空间。采用望远镜组的方案，成本也会相对较高，因为增加了两片透镜的成本。
发明内容
针对上述技术问题，本发明的目的在于提供一种解决望远镜组占用较大空间尺寸的问题，在压缩多束激光束的同时，保证空间上的紧凑度，在一些对空间紧凑度要求较高的方案下，依然可以满足使用要求,降低方案的成本，避免使用透镜缩束的方案。

具体实施方式
下面结合附图，对本实用新型的具体实施方式进行详细描述，但应当理解本实用新型的保护范围并不受具体实施方式的限制。
除非另有其它明确表示，否则在整个说明书和权利要求书中，术语“包括”或其变换如“包含”或“包括有”等等将被理解为包括所陈述的元件或组成部分，而并未排除其它元件或其它组成部分。
本发明提供了一种激光阵列装置，包括：一用于发出激光光源的激光单元和一与其对应的准直透镜，能够辐射单色光束并对光束进行准直；一组或多组反射镜组；所述反射镜组的每组由第一反射镜和与第一反射镜配对的第二反射镜组成，所述第一反射镜和第二反射镜平行设置；所述多组 激光光源组相互平行设置，使得多组激光光源组发出的光束沿同一个方向平行出射；所述反射镜配置成用于两次改变激光光源组发出的多束方向平行的光束方向，多束方向平行的光束沿一个方向集中出射,压缩激光阵列激光光束的慢轴空间。
其中，准直透镜并不是必须的，准直透镜的使用只是为了准直光束，使得光束辐射的效果更好。
其中，所述反射镜组可以由两组组成，也可以根据实际情况由1组或多组组成。
其中，所述反射镜可以设置为平面反射镜，也可以根据需要设置为曲面反射镜。
其中，所述多组激光光源组也可以根据实际需要设置成不平行，反射镜组设置成使得激光光源组的出射光束经过反射镜组反射后平行出射。
其中，所述反射镜组的每组不仅可以包括两个反射镜，也可以包括一个或更多个反射镜，每组的反射镜之间可以平行设置，也可以不平行设置，可以根据激光光源组的位置和出射方向设置反射镜的位置和出射方向，只要能够使得经反射后的光束沿同一个方向集中平行出射即可。
其中，所述激光光源组的组数可以设置成大于反射镜组的组数，且优选差为1，也可以使得差为其他数值，但是差为1时，光束集中收缩的效果最好。
其中，所述激光光源组的组数和反射镜组的组数也可以根据实际需要设置，可以将两者设置成相等，或者激光光源组的组数小于反射镜组的组数都可，且差数可以根据实际需要调整。
其中，反射镜组的每组反射镜的个数可以根据需要设置数量。可以先 设置一定数额的初级反射镜组，使得激光光源组发出的光束经初级反射镜组反射后沿几个方向或一个方向分散出射；再设置一定数额的次级反射镜组，使得经初级反射镜组反射后的光束再经次级反射镜组反射最终沿同一方向集中平行出射。其中，设置几级次级反射镜组，以及每级的反射镜组的个数和位置，结构设置可以根据实际情况设定。
其中，所述反射镜组的每组由第一反射镜和与第一反射镜配对的第二反射镜组成，所述第一反射镜和第二反射镜平行设置。
所述反射镜组的每组中的第一反射镜分别设置于激光光源组的其中一组的光路正前方；所述激光光源组的其中一组的光路正前方不设置第一反射镜；所述反射镜组的每组中的第二反射镜设置于不设置第一反射镜的所述激光光源组的其中一组发出的光束的光路前方，且不遮挡所述不设置第一反射镜的所述激光光源组的其中一组发出的光束的位置；所述反射镜组的每组中的第一反射镜接收其对应的激光光源组发出的光束并进行反射，并且将反射后的光束入射到与其对应的第二反射镜，所述第二反射镜将接收到的光束进行反射；所有通过每个第二反射镜反射后的光束相互靠近并且沿同一方向平行出射。这样设置可以改变及引导其光束走向；进而压缩了激光阵列激光光束的慢轴距离。
在本发明实施例中，所述多组平行设置的激光光源组的组数可以设置为N组，所述一组或多组平行设置的反射镜组的组数可以设置为N-1组，所述N为自然数，N的取值范围为2≤N≤20，在此数值范围内，使用本发明所述的反射镜组来压缩光束会比使用望远镜来压缩，结构上更紧凑。实际情况，N的取值范围为3≤N≤5，即对3组或者4组或者5组激光单元组进行光束慢轴压缩效果比较好，使用比较广泛。
其中，所述反射镜组的每组的第一反射镜和第二反射镜与激光光源组发出的光束的中心光轴夹角为45℃。
如图2所示，一种激光阵列装置，包括：N组平行设置的激光光源组101、102、……10N，组成的激光阵列，所述一组激光光源组包括：一激光单元和一与其对应的准直透镜，能够辐射单色光束并对光束进行准直；N-1组平行设置的反射镜组，所述反射镜组由第一反射镜和与第一反射镜配对的第二反射镜组成，如：第一反射镜A01与第二反射镜A02；第一反射镜B01与第二反射镜B02；等。第一反射镜(A01，B01，等)依次设置在N-1组平行设置的激光光源组的光路前方，其中，第N组激光光源组的光路前方不设置第一反射镜；第二反射镜(A02，B02，等)设置在第N组激光光源组的光路前方附近，且不遮挡第N组激光光源组发出的光束的光路；所述第一反射镜(A01，B01，等)和第二反射镜(A02，B02，等)等平行设置；所述反射镜组的每组中的第一反射镜(A01，B01，等)接收其对应的激光光源组发出的光束并进行反射，并且将反射后的光束入射到与其对应的(A02，B02，等)，所述第二反射镜(A02，B02，等)将接收到的光束进行反射；所有通过每个第二反射镜(A02，B02，等)反射后的光束相互靠近并且沿同一方向平行出射。所述N-1组反射镜组分别设置于N-1组激光光源组前方，用于改变及引导对应的来自激光光源组的光束，使其与第N组激光光源组的光束靠近并同向，所述第N组激光光源组前方没有设置反射镜组来改变及引导其光束走向；进而压缩了激光阵列激光光束的慢轴距离。
下面对3组激光光源组的情况进行描述，如图3所示，第一组激光光源组11、第二组激光光源组12以及第三组激光光源组13均包括一激光单元和一与其对应的准直透镜，能够辐射单色光束并对光束进行准直；第一反射镜组由平行设置的第一反射镜片M1和第二反射镜片M2组成，用于对来自第一组激光光源组11的激光光束进行两次反射，使其光束与第三组激光光源组13的光束靠近并同向；同理，第二反射镜组由平行设置的第一反射镜片N1和第二反射镜片N2组成，用于对来自第二组激光单元12的激光光束进行两次反射，使其光束与第三组激光光源组13的光束靠近并同向； 其中第一反射镜片M1和第一反射镜片N1分别设置于第一激光光源组11和第二激光光源组12的光路正前方；第三组激光单元13的光源光路前方不设置第一反射镜；第二反射镜片M2和N2设置在第三组激光单元13的光源光路前方附近，不遮挡第三组激光单元13的光源的出射路线；所述第一反射镜组和第二反射镜组平行设置；借助反射镜组，激光光源组相邻两组激光光束之间的距离由D压缩为d2。
在本发明中，所述激光阵列激光光束慢轴方向的空间填充率Fs，可以由下述公式表示：
Fs＝Sa/D
其中,Sa为激光阵列单个激光单元光束的慢轴方向的间距，D为来自激光光源组两组激光光束之间的距离；
所述激光阵列激光光束压缩比M表示：
M＝D/d2
其中，来自两平行设置的激光单元的光束间距为D，压缩后所述两激光束间距为d2。
值得注意的是，在本发明实施例中，激光阵列装置的排列方式并不限制于上述的排列方式；如图4a-图4e所示，N-1组反射镜组可以对应分别设置于任意N-1组激光光源组前方，将N-1组激光光源组的光束靠近并与第N组光束同向。其中N-1组第一反射镜片必须设置于对应的激光光源组正前方，第N组激光光源组的光路前方不设置第一反射镜片；N-1组反射镜组的第二反射镜片的位置可以设置于第N组激光光源组光束的上方或者下方，且不遮挡第N组激光光源组发出的光源光束的位置。其中所述第N组激光光源组的光路前方不设置第一反射镜片，N是可以任意选择的，根据实际情况而定。
