  • Publication number: 20210181022
    Abstract: A Fourier-transform hyperspectral imaging system may include an optical imaging system configured to produce an image of an object, and an adjustable birefringent common-path interferometer module comprising a movable birefringent element and configured to produce interfering replicas of an input radiation which are delayed from each other by a phase delay adjustable by the moving birefringent element. The interferometer module may be configured to produce collinear replicas for entering optical rays parallel to said optical axis. The hyperspectral imaging system further comprises a two-dimensional light detector configured to receive the replicas and provide digital images of the object depending on said adjustable phase delay. The system also includes an analysis device configured to perform a Fourier Transform of the digital images to obtain a hyperspectral representation of the object.

  • Patent number: 10520425
    Abstract: An integrated optofluidic device to illuminate, along an irradiation direction, a fluidic sample containing an object to be analysed, the device comprising: a substrate comprising an entry surface and being made of a material transparent to a light beam incident through the entry surface along the irradiation direction; a microfluidic channel formed in the substrate and having a channel portion intercepting the irradiation direction and extending along a longitudinal axis transverse to the irradiation direction, the microfluidic channel comprising a first flow inlet port for loading a fluidic sample therein, and an elongated lens cavity for an optofluidic cylindrical lens, the cavity being formed in the substrate and being arranged along the beam irradiation direction between the entry surface and the microfluidic channel, wherein the lens cavity is in fluid communication with a lens inlet port for loading a lens fluid.

  • Patent number: 10437038
    Abstract: The invention is directed to a method for creating an optical tomogram, which comprises the steps providing an optical microscope, arranging a sample (1) in the optical coverage region of a lens (5) of the microscope, setting the focus of the lens to a particular focal plane (2), recording an image of the sample through the microscope, rotating the sample through an angle ?, optionally displacing the sample along the longitudinal axis (z) of the lens (5) and/or perpendicular to the plane of the previously recorded image (9) and continuing the method with step d) until a predetermined number of section images (9) of the sample (1) have been recorded, wherein the sample (1) is displaced along the longitudinal axis (z) of the lens (5) and/or perpendicular to the plane of the previously recorded image (9), in accordance with step f), at least once during a rotation of the sample through 360°.

  • Patent number: 8161852
    Abstract: A rotary centering device for the transfer of a bar from the guiding channel of a feeder to a lathe, comprising a supporting element and provided with at least one circular seat in which a grip element for a bar is supported, the grip element being constituted by a bush which has a tubular portion and a plurality of sectors connected to the tubular portion, elastic elements being provided which act on the bush and are designed to control its axial movement between a first stop position, in which the sectors define a circular opening whose diameter is the same as that of the bar, and a second position, in which the sectors are moved until they form an opening to allow the passage of the bar pusher.

  • Publication number: 20110000348
    Abstract: A control and management method for lathes and loaders for lathes, comprising the steps of: detecting geometric parameters and mechanical characteristics of a bar to be turned; determining development of the critical frequencies of the bar upon a rotation thereof about the longitudinal axis as the rotation rate and length of the bar vary; starting turning of the bar, avoiding the combinations of mandrel rotation rate and bar length at which the rotation rate of the bar intersects the curves that represent the development of the critical frequencies.

  • Patent number: 7848433
    Abstract: A system, method and computer-readable media are introduced that relate to data coding and decoding. A computing device encodes received data such as video data into a base layer of compressed video and an enhancement layer of compressed video. The computing device controls drift introduced into the base layer of the compressed video. The computing device, such as a scalable video coder, allows drift by predicting the base layer from the enhancement layer information. The amount of drift is managed to improve overall compression efficiency.
