Patent number: 11204241Abstract: Provided herein is a method for measuring the size distribution and/or hardness of free falling rock pieces. The method comprises projecting at least one laser line on the falling rock pieces by a laser device; capturing images of the falling rock pieces at an angle from the at least one laser line by at least one camera; and obtaining size distribution data of the falling rock pieces based on data obtained from a topographical map generated from the captured images. Certain embodiments further comprise: obtaining at least one of the volume and area of individual rock pieces from the topographical map; conducting a data analysis on at least one of the volume and area measurements of the rock pieces to reduce at least one of sampling and measurement errors; determining the size distribution of the falling rock pieces based on the data analysis and, optionally, evaluating a rock hardness index for the rock.Type: GrantFiled: February 15, 2018Date of Patent: December 21, 2021Assignees: Her Majesty The Queen in Right of Canada as Represented by the Minister of Natural Resources Canada, Institut National d'Optique/National Optics InstituteInventors: Magella Bilodeau, Andre Demers, Daniel Lefebvre, Sebastien Roy

Patent number: 6445508Abstract: An optical system for focusing an incident light so as to obtain a linear output (as a function of the wavelength, or of the order of diffraction, or of the grating spacial frequency or of the inverse of the index of refraction) comprises a diffraction grating and a lens, or a group of lenses, having a f-Sin(&thgr;) characteristic, where f is the effective focal length of the lens, or group of lenses, and &thgr; is an output angle of the light exiting from the diffraction grating. Therefore, a light incident on the diffraction grating reaches the lens, or the group of lenses, and results in a linear output. Using the present invention in a spectrometer reduces the time consuming calibration process required and renders it easier because of the linear output between wavelength and pixels positions. The lens, or group of lenses, has a diffractive, refractive or reflective property, or any combination thereof. The incident light can be a collimated, converging or diverging beam.Type: GrantFiled: September 24, 1999Date of Patent: September 3, 2002Assignee: National Optics InstituteInventor: Simon Thibault

Patent number: 6025951Abstract: The invention relates to spatial light modulators (SLM) for amplitude and phase modulation of incident light. A "flexure" hinge which is provided between the SLM's substrate and micromirror comprises integral hinged sections which allow for the micromirror to tilt or to move in a piston-like fashion relative to the substrate in response to an electrostatic force. The hinge is particularly advantageous for large mirrors. In addition, the hinge can provide improved heat sinking capability over previously reported SLM hinge designs based on torsion bars and cantilever beams. The flexure hinge has sufficient mechanical flexibility that the SLM actuation voltage required is not excessively high. The flexure hinge has many applications, the preferred ones being a SLM for modulating high-energy beams and a SLM for optical channel switching.Type: GrantFiled: November 27, 1996Date of Patent: February 15, 2000Assignee: National Optics InstituteInventors: Nicholas R. Swart, Hubert Jerominek
