Enhanced multi-wavelength holographic profilometry by laser mode selection
(2006-10-19)
The application of multi-wavelength holography for surface shape measurement is presented. In our holographic setup a Bi12TiO 20 (BTO) photorefractive crystal was the holographic recording medium and a multimode diode laser ...

Rock lithological classification by hyperspectral, range 3D and color images
(Elsevier B.V., 2019)
Mine operations in the future will require automatic rock characterization at many different stages, since it can be used to supervise and optimize various processes in the laboratory as well as at the mine locations for ...
Classification of rock lithology by laser range 3D and color images
(Elsevier, 2017)
The determination of hardness and approximate mineral composition of rocks and classifying these litholo-gies aids in controlling various processes in the plant, such as reducing the grinding process, which accountsfor ...
Automated vision-based system for parallel contactless micromanipulation
(Institute of Electrical and Electronics Engineers, 2013-11)
This paper presents the automated parallel noncontact manipulation of glass beads ranging from 30 up to 300 μm in size under water. Non-contact micromanipulation is performed by generating controllable laser-induced ...
Camera and laser range finder fusion for real-time car detection
(10/29/2014)
This paper describes a car detection method by combining data obtained from a laser and a camera. Data from the camera and the laser range finder (LRF) are combined after a calibration method has been performed. The ...
Holographic imaging with multimode, large free spectral range lasers in photorefractive sillenite crystals
(Springer, 2005-03-01)
The holographic imaging of rigid objects with diode lasers emitting in many wavelengths in a sillenite Bi12TiO20 photorefractive crystal is both theoretically an experimentally investigated. It is shown that, due to the ...
