[Design and implementation of a long wavelength near infrared spectrometer based on MEMS scanning mirror].

Long Wavelength Near InfraRed (LW-NIR) spectrometer has wide applications. Miniaturization and low-cost are two major goals of the development of LW-NIR spectrometer in the industrial or research community. Under the background that having a trend of spectrometer miniaturization and integration, method and main problems involved in miniaturization of LW-NIR spectrometer through MEMS scanning mirror, such as the design strategy of the light-splitting optical system, selection considerations of the MEMS scanning mirror, design method of the preamplifier circuit, etc, have been presented in detail.

High-throughput acousto-optic-tunable-filter-based time-resolved fluorescence spectrometer for optical biopsy.

Time-resolved fluorescence spectroscopy has been studied to perform minimally invasive optical biopsy in clinical diagnostics. A critical barrier preventing current time-resolved techniques from clinical studies is their impractically long data acquisition time. We have developed an acousto-optic-tunable-filter (AOTF)-based time-resolved fluorescence spectrometer, which is capable of near real-time data acquisition.
