Journal of Micromechanics and Microengineering, 2017 Abstract This work presents an electromagnetic scanning mirror integrated with blazed grating and an angle sensor for a near infrared micro spectrometer. This device is fabricated on an aluminum coated 7.9° off-oriented (1 1 1) silicon substrate by utilizing the micro-electro-mechanical systems (MEMS) technology.

The stray light of gratings lowers the image contrast of augmented reality display devices based on lightguide gratings. We propose to reduce the stray light of gratings fabricated with the scanning exposure method in a Lloyd’s mirror interferometer setup.

To overcome the problems of poor structural reliability, high driving voltage and small scanning angle, a novel electromagnetic MOEMS scanning grating mirror (SGM) with folded torsion beam is reported in this work. Compared with the conventional straight torsion beam, the folded torsion beam has better elastic torsion property and can effectively ...

Near infrared micro-spectrometer (NIRMS) as a vital detection equipment for various elements has been investigated over the last few years. Traditional MEMS NIRMS employs CCD array detectors for NIR spectrum collection and this leads to higher fabrication cost. In this paper, to ensure the higher diffraction efficiency as well as lower fabrication cost,
