    Abstract: A method is described including displaying a user's body portion image on an optical display of a device employed by the user. The device may include an image sensor and the body portion image may be sensed by the sensor. The method includes determining whether a position of the body portion image relative to the sensor is acceptable to allow for recording of the body portion image; determining whether a lighting environment associated with the sensor is acceptable to allow for recording of the body portion image; recording the image using the sensor to provide a recorded image having image data; processing the recorded image to determine lighting model data associated with the lighting environment; and determining reflectance and color characteristics associated with the body portion based on the recorded image and the lighting model data. In one embodiment the optical display has an illuminant and when the lighting environment is not acceptable for recording, the method instructs the user to modify the lighting environment so that illumination of the body portion is less than about 2% of the illumination provided by the illuminant, illuminates the body portion with constant white light using the illuminant and determines whether the illuminated body portion is positioned relative to the sensor to allow for recording of the body portion image by displaying an outline of the body portion on the optical display to position the body portion in view of the sensor. Processing of the image in this case may include direct computation to determine the lighting model.

    Abstract: Ultra-miniature spatial heterodyne spectrometers (SHSs) are presented. Ultra-miniature SHSs in accordance with the invention, comprise a beam-splitter and gratings configured to generate a fringe pattern for spectroscopic detection. Many embodiments include input optics and a sensor and are configured in a way to omit collimating optics and imaging optics from the SHS. Compared to conventional SHSs known in the art, the present invention enables fewer parts, significantly smaller and lighter SHSs, are more efficient and robust, and require less maintenance. Many embodiments are field-deployable, in that such embodiments can be deployed for hand held use in real-world or remote activities outside of research or diagnostic facilities.

    Abstract: An example system includes a first spectrometer, a second spectrometer, and an electronic control device communicatively coupled to the first spectrometer and the second spectrometer. The first spectrometer is operable to emit first light using a first light source towards a sample region between the first spectrometer and the second spectrometer. The first spectrometer is also operable to measure first reflected light reflected using a first photodetector from an object in the sample region. The second spectrometer is operable to measure first transmitted light transmitted through the object using a second photodetector. The electronic control device is operable to determine, based on at least one of the measured first reflected light or the measured first transmitted light, a spectral distribution of light corresponding to the object.

    Abstract: State-of-the-art portable Raman spectrometers use discrete free-space optical components that must be aligned well and that don't tolerate vibrations well. Conversely, the inventive spectrometers are made with monolithic photonic integration to fabricate some or all optical components on one or more planar substrates. Photonic integration enables dense integration of components, eliminates manual alignment and individual component assembly, and yields superior mechanical stability and resistance to shock or vibration. These features make inventive spectrometers especially suitable for use in high-performance portable or wearable sensors. They also yield significant performance advantages, including a large (e.g., 10,000-fold) increase in Raman scattering efficiency resulting from on-chip interaction of the tightly localized optical mode and the analyte and a large enhancement in spectral resolution and sensitivity resulting from the integration of an on-chip Fourier-transform spectrometer.
