    Abstract: Provided are methods and systems for concurrent imaging at multiple wavelengths. In one aspect, a hyperspectral/multispectral imaging device includes a lens configured to receive light backscattered by an object, a plurality of photo-sensors, a plurality of bandpass filters covering respective photo-sensors, where each bandpass filter is configured to allow a different respective spectral band to pass through the filter, and a plurality of beam splitters in optical communication with the lens and the photo-sensors, where each beam splitter splits the light received by the lens into a plurality of optical paths, each path configured to direct light to a corresponding photo-sensor through the bandpass filter corresponding to the respective photo-sensor.

    Abstract: The disclosure provides methods and systems for determining tissue oxygenation. An electronic device obtains a data set including a plurality of images of a tissue of interest, each resolved at a different spectral band. Spectral analysis is performed, upon image registration, at a plurality of points in a two-dimensional area of the images of the tissue. The spectral analysis including determining approximate values of oxyhemoglobin levels and deoxyhemoglobin levels at each respective point in the plurality of points. The predetermined set of eight to twelve spectral bands includes spectral bands that provide improved methods for measuring tissue oxygenation.

    Abstract: A hyperspectral/multispectral imager comprising a housing is provided. At least one light source is attached to the housing. An objective lens, in an optical communication path comprising originating and terminating ends, is further attached to the housing and causes light to (i) be backscattered by the tissue of a subject at the originating end and then (ii) pass through the objective lens to a beam steering element at the terminating end of the communication path inside the housing. The beam steering element has a plurality of operating modes each of which causes the element to be in optical communication with a different optical detector in a plurality of optical detectors offset from the optical communication path. Each respective detector filter in a plurality of detector filters covers a corresponding optical detector in the plurality of optical detectors thereby filtering light received by the corresponding detector from the beam steering element.

    Abstract: Disclosed are hyperspectral/multiple spectral imaging methods and devices. A method obtains first and second spectral image datasets of a region of interest (ROI). The first spectral image dataset is characterized by a first spectral range and the second spectral image dataset is characterized by a second spectral range. The method then performs a first spectral analysis on the first spectral image dataset and a second spectral analysis on the second spectral image dataset. Afterwards, the method determines one or more spectral signature(s) at a deeper layer of the ROI.

    Abstract: An attachment device comprising a cover, with first and second windows, is affixed to a backing, with third and fourth windows, thereby forming a casing. The first and third windows form a first optical path with light entering the third window passing through the first window. The second and fourth windows form a second optical path with light entering the second window passing through the fourth window. A filter housing with a plurality of filters is driven by a motor so that the filters intercept the first optical path in accordance with an imaging regimen electronically stored in the casing interior. The imaging regimen communicates instructions, via a communications interface of the attachment device, to an imager and light source of an external device, to which the attachment device is attached, thereby controlling these components in accordance with the regimen.
