Described are devices, systems and methods for thermographic imaging of conditions of the ear, nose, and throat (ENT). An example device for thermographic ENT imaging includes an endoscope and a thermal imaging camera that can be either integrated or added as an attachment to the endoscope. The device may also include a mirror configured to direct thermal radiation emitted by a target area to the thermal imaging camera.

Thermal imaging endoscope

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.

Compact optical spectrometers are provided to measure optical spectral composition of light.

Miniaturized and integrated photonic spectrometers

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.

Optical phase modulation systems and methods

This disclosure provides apparatus, systems and methods for an electromechanical systems (EMS) device having one or more flexible support posts. In one aspect, the EMS device includes a substrate, a stationary electrode over the substrate, one or more flexible support posts over the substrate, and a movable electrode over the stationary electrode and supported by the one or more flexible support posts. The movable electrode is configured to move across a gap between the movable electrode and the stationary electrode upon electrostatic actuation, where the one or more flexible support posts include a first organic material and can be configured to compress to permit the movable electrode to move across the gap.
