Structured light is the process of projecting a known pattern (often grids or horizontal bars) on to a scene. The way that these deform when striking surfaces allows vision systems to calculate the depth and surface information of the objects in the scene, as used in structured light 3D scanners .
A structured-light 3D scanner is a device that measures the three-dimensional shape of an object by projecting light patterns—such as grids or stripes—onto it and capturing their deformation with cameras. [1]
The active stereo vision is a form of stereo vision which actively employs a light such as a laser or a structured light to simplify the stereo matching problem. The opposed term is passive stereo vision. Conventional structured-light vision (SLV) employs a structured light or laser, and finds projector-camera correspondences. [2] [3]
Structured illumination light sheet microscopy (SI-LSM) is an optical imaging technique used for achieving volumetric imaging with high temporal and spatial resolution in all three dimensions. It combines the ability of light sheet microscopy to maintain spatial resolution throughout relatively thick samples with the higher axial and spatial ...
Lattice light-sheet microscopy is a modified version of light sheet fluorescence microscopy that increases image acquisition speed while decreasing damage to cells caused by phototoxicity. This is achieved by using a structured light sheet to excite fluorescence in successive planes of a specimen, generating a time series of 3D images which can ...
A white light scanner (WLS) is a device for performing surface height measurements of an object using coherence scanning interferometry with spectrally-broadband, "white light" illumination. Different configurations of scanning interferometer may be used to measure macroscopic objects with surface profiles measuring in the centimeter range, to ...
Structured notes were beloved by Wells Fargo bankers. The SEC warns that they are incredibly risky for the average investor. Structured notes offer investors options that are otherwise unavailable ...
Although the term "structured illumination microscopy" was coined by others in later years, Guerra (1995) first published results [30] in which light patterned by a 50 nm pitch grating illuminated a second grating of pitch 50 nm, with the gratings rotated with respect to each other by the angular amount needed to achieve magnification. Although ...
