Publication number: 20200400805Abstract: A subsurface imaging technique using distributed sensors is introduced. Instead of monostatic transceivers employed in conventional ground penetrating radars, the proposed technique utilizes bi-static transceivers to sample the reflected signals from the ground at different positions and create a large two-dimensional aperture for high resolution subsurface imaging.

In addition, it eliminates the need for sampling on a grid which is a time-consuming task in imaging using ground penetration radar.

Publication number: 20200400826Abstract: Hyperspectral, fluorescence, and laser mapping imaging with reduced fixed pattern noise is disclosed. A method includes actuating an emitter to emit a plurality of pulses of electromagnetic radiation and sensing reflected electromagnetic radiation resulting from the plurality of pulses of electromagnetic radiation with a pixel array of an image sensor. The method includes reducing fixed pattern noise in an exposure frame by subtracting a reference frame from the exposure frame. The method is such that at least a portion of the pulses of electromagnetic radiation emitted by the emitter comprises one or more of: electromagnetic radiation having a wavelength from about 513 nm to about 545 nm, from about 565 nm to about 585 nm, from about 900 nm to about 1000 nm, an excitation wavelength of electromagnetic radiation that causes a reagent to fluoresce, or a laser mapping pattern.Type: ApplicationFiled: January 7, 2020Publication date: December 24, 2020Applicant: Ethicon LLCInventors: Joshua D.

Publication number: 20200400827Abstract: A laser detecting device able to detect and map all the contours a target object can configure and apply at least two scanning point groups on the target object. Each scanning point group includes at least two scanning points. The laser detecting device includes four light sources at different angles of incidence in relation to a diffracting element. A beam receiving element receives all the light reflected by the target object, and a central controller records emitting and receiving times of the light emitted and received. The detection beams sequentially scan the at least two scanning point groups as the central controller switches on in turn one of the four light sources as the others are powered off. Processing of data from the beam receiving element enables a three-dimensional image of the target object to be obtained.Type: ApplicationFiled: January 16, 2020Publication date: December 24, 2020Inventors: MING-YANG PAN, CHI-WEN HUANG, CHIA-CHU LIN
