Abstract: Methods, systems, and devices for particle characterization by optical phase modulation and detection of aerosol backscattering. In some aspects, a compact and cost effective particle detector device to measure the aerosol density and its size distribution by backscattered focusing using projected optical modified field distribution imaging into the aerosol medium (air). The disclosed device can be used in a variety of scientific and industrial applications, e.g., such as a particle sensor for automobiles able to detect harmful pollution which may then be filtered from the car cabin, or warnings provided to the driver. The device can also capture and store data, enabling detailed pollution maps of various roadways in real-time.

Abstract: Devices, systems and methods for optical spectroscopy using a Fourier transform that improve measurement speed, and relax the sampling rate and dynamic range requirements compared to conventional techniques, are described. One exemplary method for optical Fourier transform spectroscopy includes receiving a broadband signal, spectrally partitioning the broadband signal to generate a plurality of spectral channel interferograms, computing a one- dimensional Fourier transform of a function of each of the plurality of spectral channel interferograms to generate each of a plurality of channel spectrums, and reconstructing a spectrum of the broadband signal based on the plurality of channel spectrums. Embodiments of the disclosed technology include a free-space channel dispersed Fourier transform spectrometer and an integrated silicon-on-insulator Fourier transform spectrometer.
