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 new innovative way for connecting multiple thermal imaging sensors to a base unit while only using one port of the base unit when connected to such a base unit; this by using a daisy chained connection between the sensors themselves. The thermal imaging sensor(s) connect to each other using a wired connectivity with or without being connected directly or indirectly to a base unit. The thermal imaging sensor in this invention is not a single standalone unit but consists of at least 2 physical different devices that are connected to each other using a wired connection.

Abstract: A method of improving performance of an averager is provided. The method includes steps of: (a) multiplying a value of a (n−1)th piece of output data by a value “N” to calculate a temporary value; (b) determining whether or not a difference between an nth piece of input data and the (n−1)th piece of output data is larger than or smaller than a zero value, if yes, compensating the temporary value to obtain a correction value and performing step (c), if no, setting the correction value and performing step (c); (c) dividing the correction value by the value “N” to obtain a first value; (d) subtracting the first value from the correction value and adding up the correction value and the nth piece of input data to obtain a second value; and (e) dividing the second value by the value “N” to calculate an output value of the averager.

Abstract: A shade matching method for a tooth obtains a plurality of digitized tooth shade references, obtains a three-dimensional (3D) surface representation of a tooth and associated color information defined on the three-dimensional (3D) surface, selects a region on the three-dimensional (3D) surface representation of the tooth, determines a plurality of correspondences with the common tooth shape of all the tooth shade references, computes color difference with each of the tooth shade reference from the plurality of tooth shade references, and records the label corresponding to the shade reference with a smallest difference.

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.

Moreover, the scanning based THz imaging device is much sufficiently sensitive as compared with the common X-ray imaging device. Therefore, the scanning based THz imaging device has the potential to operate in the density for early detection problems such as dental caries or demineralization of the enamel in the teeth. Also provided is a method for diagnosing or imaging the target in the subject by using the scanning based THz imaging device of the present disclosure.

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.
