    Abstract: Provided are a fluorescence imaging probe and a handheld imaging prober, relating to the technical field of medical devices. The fluorescence imaging probe includes a dichroic filter and an image detector, the dichroic filter is arranged at an included angle of 45° with a direction of a main optical axis of incident excitation light, the incident excitation light is reflected by the dichroic filter to a target detection position, the reflected incident excitation light excites a fluorescent substance at the target detection position to form fluorescence, a main optical axis of the fluorescence is arranged coaxially with the image detector, the fluorescence is incident to the image detectors through the dichroic filter, and the image detector converts the received fluorescence into an image signal.

    Abstract: In general, an imaging system to synchronously record a spatial image and a spectral image of a portion of the spatial image is described. In some examples, a beam splitter of the imaging system splits an optical beam, obtained from a viewing device, into a first split beam directed by the imaging system to a spatial camera and a second split beam directed by the imaging system to the entrance slit of an imaging spectrograph that is coupled to a spectral camera. An electronic apparatus synchronously triggers the spatial camera and the spectral camera to synchronously record a spatial image and a spectral image, respectively.

    Abstract: A method of adaptively scanning a selected area that includes selecting an imaging mode, performing a scan of the selected area using the imaging mode, detecting an item of interest, automatically selecting a new imaging mode in response to detecting the item of interest, and performing a scan of the item of interest using the new imaging mode. The imaging mode may determine at least one of a scanning pattern, a scanning speed, and a scanning rate. Spectral data and image data may be gathered and used to detect the item of interest. The method may also include providing a scanning spectrometer system that has a gimbal system configured to provide at least two degrees of freedom to the scanning spectrometer system. The gimbal system may have a spectrometer and a camera each mounted on the gimbal system and configured to gather the spectral data and the image data, respectively.

    Abstract: A computer-implemented method can include providing via a digital display a graphical user interface including one or more selectable elements for retrieving spectrophotometer data measured from a target asset. The method also includes receiving spectrophotometer data from an end user of the graphical user interface, and retrieving from a database a plurality of closest match colors corresponding to the spectrophotometer data. In addition, the method can include displaying a plurality of selectable color tiles corresponding to the retrieved closest match colors, and further displaying an image for each of one or more selectable sub-component options corresponding to one or more alternate formulas for at least one of the selectable color tiles. The method further includes displaying both the adjusted formula and related sub-components corresponding to the user modifications, as well as options to select the color as a coating for eventual application.
