| 1 | Snapshot imaging spectrometer based on a microlens array显示文摘This Letter proposes a snapshot imaging spectrometer, which obtains the spectral information and spatial information in one 'shot'. The device proposed can achieve the data cube size of 21 × 29 × 40 in the waveband of400–800 nm. The core element of this system is the microlens array, which contains 60 × 60 microlenses in a square arrangement, each microlens has an aperture of 125 μm× 125 μm, and the F number is 15. The microlens array is mounted in a rotation mount, which provides 360° of rotation around the optical axis to maximize the spectral resolution. The final resolution of the system is about 10 nm. | 张泽霞 常军 任虹禧 樊恺元 李冬梅 | 2019 | Chinese Optics Letters2019，17，1： | 2 |
| 2 | Fabrication of Diffraction-limited Full Aperture Microlens Array by Melting Photoresist显示文摘A further study on the fabrication of diffraction--limited full aperture microlens array by melting photoresist is described. The formation of aspherical surface is considered. The parameters for controlling the process of lens production, the height of original photoresist cylinders and the angle of contact between the melted photoresist and the substrate, are discussed in detail. The diffraction limited full--aperture microlens arrays have been obtained,and some measurement results are shown in the paper. A method of controlling the formation of quality microlens array in real time is suggested. | 高应俊 | 1997 | High Technology Letters1997，3，1： | 0 |
| 3 | Mechanism of brittle fracture in diamond turning of microlens array on polymethyl methacrylate显示文摘Diamond cutting is a popular method to fabricate microlens array (MLA) on polymethyl methacrylate (PMMA);however, it is limited by brittle fracture, which is formed easily on the surface of MLA during the cutting process. In this paper, the formation mechanism of the brittle fracture is studied via a series of experiments including the slow tool servo (STS) cutting experiment of MLA, surface scratching experiment and suddenstop cutting experiment. The effects of undeformed chip thickness, feed rate, and machining track on brittle fracture formation are investigated in detail. In addition, based on the fracture formation mechanism, a bi-directional cutting approach is proposed to eliminate the regional brittle fracture of the microlens during diamond cutting. An experiment was then conducted to verify the method;the results demonstrated that bi-directional cutting could eliminate brittle fracture entirely. Finally, a spherical MLA with the form error (vPV) of 60 nm and the surface roughness (Ra) of 8 nm was successfully fabricated. | Tian-Feng Zhou Ben-Shuai Ruan Jia Zhou Xiao-Bin Dong Zhi-Qiang Liang Xi-Bin Wang | 2019 | Advances in Manufacturing2019，7，2： | 0 |
