Near-Infrared Grating Spectrometer for Mobile Phone Applications
Near-infrared (NIR) spectroscopy is a well-established technique for the chemical analysis of organic and inorganic matter. Accordingly, spectroscopic instrumentation of different complexity has been developed and is currently commercially available. However, there are an increasing number of new mobile applications that have come into focus and that cannot be addressed by the existing technolo...
متن کاملA Near-Infrared Spectrometer Based on Novel Grating Light Modulators
A near-infrared spectrometer based on novel MOEMS grating light modulators is proposed. The spectrum detection method that combines a grating light modulator array with a single near-infrared detector has been applied. Firstly, optics theory has been used to analyze the essential principles of the proposed spectroscopic sensor. Secondly, the grating light modulators have been designed and fabri...

متن کاملA field-portable thermal infrared grating spectrometer (THIRSPEC)
A thermal infrared grating spectrometer was developed for field studies in the earth sciences. The design is based on a reflection grating and a 60-element HgCdTe detector array. The useful spectral range of the instrument covers 7.9-11.3 pm with a Nyquist limited resolution of 0.16 pm. The instrument averages over a 12" field of view and compares the exitance of the target to that of an intern...
متن کاملWidely tunable monolithic narrowband grating filter for near-infrared radiation.
We propose a monolithic narrowband guided-mode grating filter in fused silica that is widely tunable in the near-IR wavelength region. Based on a recently demonstrated approach for a monolithic reflector comprising an encapsulated grating, we theoretically investigate such a device by means of rigorous modeling aimed at a narrow linewidth. It is demonstrated that upon a spatial variation of the...
