Abstract: In this paper, a novel rotational MEMS diffraction grating for realization of micro-sized spectroscope system with SiOB (Silicon Optical Bench) technology is newly developed, and its ...

The diffraction grating of a spectrometer partially determines the optical resolution that can be achieved by the spectrometer and also determines the wavelength range. Selecting the correct grating ...

IT may be of interest to give a preliminary account of what I believe to be a new method of producing acoustic spectra. The method, which is to employ the striations on “variable-density” sound-film ...
