LENS-ARRAY IMAGER

A lens array imager includes: lenses Lm forming a lens array having a pitch dx; a pixel array comprising a pixel array region Rm; and a perforated baffle layer therebetween; wherein m = {0, 1, 2,...}. Each pixel array region has a width rx < dx and a pitch px < dx. Each perforated baffle layer is located at a respective distance zk from the array of pixels, respectively, and has a respective plurality of aperture diaphragms Am forming an array of aperture diaphragms, respectively. The center of each aperture diaphragm Am is collinear with the center of the region Rm and the optical center of the lens Lm. Each aperture diaphragm array has a pitch; the pitch approaches px as zk approaches zero and the lens pitch dx as zk approaches a distance zL between the lens L0 and the region R0. The width of each aperture stop Am has an upper limit that increases from px when zk is equal to zero to Wx when the distance zk is equal to zL. 本发明提供一种透镜阵列成像器，包括：形成具有节距dx的透镜阵列的透镜Lm，包括像素阵列区域Rm的像素阵列，以及在它们之间的有孔挡板层；m＝{0，1，2，...}。每个像素阵
