从可编程 MEMS 光调制到红外阵列:把像素指标放回系统测试From programmable MEMS light modulation to infrared arrays: put pixel metrics back into system tests
依据 Fraunhofer IPMS 的两份官方发布整理。机构披露的器件信息与微纳Hub的项目准备建议明确区分。Based on two official Fraunhofer IPMS releases. Institutional device disclosures are distinct from MN Fab Hub project-preparation advice.
光调制:像素可寻址性不等于整机光学表现Light modulation: pixel addressability is not system-level optics
Fraunhofer IPMS 于 9 月 8 日介绍其衍射式 MEMS 器件:256 × 256 个可独立寻址的倾斜微镜,单元边长 16 μm,可用于 DUV 及更长波段的光束控制。该信息描述的是器件与评估套件能力;实际衍射效率、光束质量和系统分辨率仍取决于波长、入射光路、驱动方式与后续测试。On September 8, Fraunhofer IPMS described a diffractive MEMS device with 256 × 256 independently addressable tilting mirrors, each 16 μm wide, for DUV and longer-wavelength beam control. This describes a device and evaluation kit; diffraction efficiency, beam quality and system resolution still depend on wavelength, illumination, drive conditions and testing.
红外阵列:目标温度分辨率需要写明测试边界Infrared arrays: state the test boundary behind a target resolution
Fraunhofer IPMS 在 7 月 7 日的 HITACT 项目发布中说明,团队正将高效热电材料集成至 CMOS 兼容制造技术,目标是被动阵列达到低于 20 mK 的温度分辨率、像素小于 45 μm;后续阶段计划形成带集成 CMOS 驱动电子学的有源阵列。以上为项目目标与开发路径,并非通用产品规格或交付承诺。In its July 7 HITACT release, Fraunhofer IPMS says it is integrating efficient thermoelectric materials into CMOS-compatible manufacturing, targeting passive arrays below 20 mK temperature resolution with pixels under 45 μm; a later phase plans active arrays with integrated CMOS drive electronics. These are project targets and a development path, not universal product specifications or delivery commitments.
一个工艺观察Process Note
像素参数、驱动与应用测试应拆开验收Accept pixel parameters, drive and application testing separately
微纳Hub编辑观察:微镜阵列的单元尺寸、填充方式和寻址结构,应与光源波长、入射角、光学系统及目标图样分开记录;热电红外阵列则应同时写清背景温度、目标温差、积分时间、标定方法和读出链路。只有测试条件可追溯,像素级数字才适合进入方案比较。MN Fab Hub editorial note: record micromirror dimensions, fill strategy and addressing separately from wavelength, incidence angle, optics and target pattern. For thermoelectric IR arrays, state background temperature, target temperature difference, integration time, calibration and readout chain. Pixel-level numbers become comparable only when test conditions are traceable.
项目准备提醒Project Prep
提交一页结构、光路或热学测试表Submit a one-page structure, optical or thermal test sheet
光调制项目可列出阵列版图、单元尺寸、反射层或镀膜、工作波长、入射角、驱动接口和目标光学测试;红外项目可列出材料与膜层、像素几何、封装窗口、热源或黑体条件、读出方式和验收指标。将目标值与已有实测值分栏,未知条件标为待确认。微纳Hub可协助梳理需求并对接加工与表征资源。For light-modulation projects, list array layout, unit size, reflector or coating, wavelength, incidence angle, drive interface and optical test target. For IR projects, list materials and films, pixel geometry, package window, heat-source or blackbody conditions, readout and acceptance metrics. Separate targets from measurements and flag unknowns. MN Fab Hub can help organize requirements and match fabrication and metrology resources.
