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 remote sensing system for time-of-flight measurements may comprise an array of laser diodes with Bragg reflectors operating in the near-infrared wavelength range synchronized to a detection system comprising lenses, spectral filters and a photodiode array coupled to a processor. The time-of-flight depth information may be combined with various camera imaging systems. The camera system may comprise a lens system, prism and a sensor. In another embodiment, the data from two cameras may be combined with the time-of-flight depth information. Yet another embodiment comprises an imaging system with another array of laser diodes followed by a beam splitter and a detection system. The remote sensing system may be coupled to a smart phone, tablet or wearable device, and the combined data may provide three-dimensional information about at least some part of an object. Also, artificial intelligence may be used in the processing to make decisions regarding the depth and images.

Abstract: The present disclosure is directed to devices and methods for synchronizing capturing of spectral images with the capturing of thermal images. A thermal imaging device of an aerial vehicle captures a sequence of thermal image of thermal images. Capturing of spectral images by a spectral imaging device of the aerial vehicle is synchronized with the capturing of the thermal images. Irradiance data indicative of a background temperature is sensed. A digital surface model of an area of interest is generated based on the sequence of spectral images. An emissivity of a target is estimated and a temperature of a pixel of the digital surface model of the target is estimated based on the sequence of thermal images, the irradiance data indicative of the background temperature and the estimated emissivity of the target.

Abstract: Optical spectrometers may be used to determine the spectral components of electromagnetic waves. Spectrometers may be large, bulky devices and may require waves to enter at a nearly direct angle of incidence in order to record a measurement. What is disclosed is an ultra-compact spectrometer with nanophotonic components as light dispersion technology. Nanophotonic components may contain metasurfaces and Bragg filters. Each metasurface may contain light scattering nanostructures that may be randomized to create a large input angle, and the Bragg filter may result in the light dispersion independent of the input angle. The spectrometer may be capable of handling about 200 nm bandwidth. The ultra-compact spectrometer may be able to read image data in the visible (400-600 nm) and to read spectral data in the near-infrared (700-900 nm) wavelength range. The surface area of the spectrometer may be about 1 mm2, allowing it to fit on mobile devices.

A processor collects and records measurement data from the devices interacting with the laser beam and calculates optical power data, irradiance data, and wavelength data. A storage device stores a first set of data comprising video data from said camera system and a second set of data comprising optical power data, irradiance data, and wavelength data, wherein said first and second set of data are timestamped, separated, and not comingled.
