微透镜阵列成像装置
摘要：
本发明提供了一种微透镜阵列成像装置，其包括主透镜、微透镜阵列以及位于微透镜阵列的远离所述主透镜一侧的图像采集单元，所述微透镜阵列包括多个阵列排布的子透镜，其中，所述主透镜对物体所成的第一图像位于所述主透镜与所述微透镜阵列之间，且所述第一图像经过每个子透镜后在所述图像采集单元上成一个第二图像，每个第二图像包括一个像圆以及围绕所述像圆的弥散圆，所述微透镜阵列成像装置的厚度与所述微透镜阵列的焦距成正比。所述微透镜阵列成像装置通过减少所述微透镜阵列的焦距，从而可以减少所述微透镜阵列成像装置的厚度。
摘要（英）：

The invention provides a micro lens array imaging device, comprising a main lens, a micro lens array and an image collection unit which is arranged on one side of the micro lens array which is away from the main lens; the micro lens array comprises a plurality of sub-lenses which are arranged in an array manner; a first image formed by the main lens on the object is positioned between the main lens and the micro lens array; the first image forms a second image on the image collection unit after going through each sub-lens; each second image comprises an image circle and confusion cycles surrounding the image cycle; and the thickness of the micro lens array imaging device is in direct proportion to the focal length of the micro lens array. The micro lens array imaging device can reduce the thickness of the micro lens array imaging device through reducing the focal length of the micro lens array.
