| 1 | 3D printed optics with nanometer scale surface roughness显示文摘Complex optical devices including aspherical focusing mirrors,solar concentrator arrays,and immersion lenses were 3D printed using commercial technology and experimentally demonstrated by evaluating surface roughness and shape.The as-printed surfaces had surface roughness on the order of tens of microns.To improve this unacceptable surface quality for creating optics,a polymer smoothing technique was developed.Atomic force microscopy and optical profilometry showed that the smoothing technique reduced the surface roughness to a few nanometers,consistent with the requirements of high-quality optics,while tests of optical functionality demonstrated that the overall shapes were maintained so that near theoretically predicted operation was achieved.The optical surface smoothing technique is a promising approach towards using 3D printing as a flexible tool for prototyping and fabrication of miniaturized high-quality optics. | Nina Vaidya Olav Solgaard | 2018 | Microsystems & Nanoengineering2018，4，1： | 2 |
| 2 | Design and fabrication of silicon-tessellated structures for monocentric imagers显示文摘Compared with conventional planar optical image sensors,a curved focal plane array can simplify the lens design and improve the field of view.In this paper,we introduce the design and implementation of a segmented,hemispherical,CMOS-compatible silicon image plane for a 10-mm diameter spherical monocentric lens.To conform to the hemispherical focal plane of the lens,we use flexible gores that consist of arrays of spring-connected silicon hexagons.Mechanical functionality is demonstrated by assembling the 20-μm-thick silicon gores into a hemispherical test fixture.We have also fabricated and tested a photodiode array on a siliconon-insulator substrate for use with the curved imager.Optical testing shows that the fabricated photodiodes achieve good performance;the hemispherical imager enables a compact 160°field of view camera with >80% fill factor using a single spherical lens. | Tao Wu Stephen S.Hamann Andrew C.Ceballos Chu-En Chang Olav Solgaard Roger T.Howe | 2016 | Microsystems & Nanoengineering2016，2，1： | 1 |
