Abstract:
A spectroscopic instrument comprising a compartment (2) for housing instrument components (3) and desiccant (4) to protect the instrument components, and a deformable container (5) having at least one wall portion which is movable within the compartment (2) so as to vary the volume of the compartment (2) that is occupied by the deformable container as the container is deformed. The interior of the deformable container (5) is in fluid communication with the surroundings of the instrument, such that a difference in pressure between the compartment and the surroundings tends to cause the deformable container to deform, moving the wall portion.
Abstract:
An illumination device is provided with a light source, a photodetector, and a support structure. The light source, which emits light, has light distribution in which a reference axis serves as an axis of symmetry or light distribution in which a plane including the reference axis serves as a plane of symmetry. A first light beam in the light is guided to the object to be illuminated. A second light beam in the light is guided to the photodetector. The photodetector detects intensity of the second light beam. The light source and the photodetector are supported by the support structure in positions and postures that allow the first light beam and the second light beam to be guided in an aforementioned manner. A traveling direction of the first light beam and a traveling direction of the second light beam make the same angle with the reference axis.
Abstract:
A tool for positioning a scanning device provided with a spectrometer comprises: a support having a resting zone suitable for being rested onto a surface, a fixing arrangement for fixing the scanning device to the tool. The support is so dimensioned as to leave uncovered an operative zone in which the spectrometer is movable for acquiring an image provided on a substrate, so that the spectrometer can acquire the image while the support is resting directly on the substrate.The tool further comprises a vision device comprising a video camera for recording the image and a control unit that controls the video camera, the control unit being programmed to recognise pre-established points of the image recorded by the video camera.
Abstract:
Imaging tools can be fixedly or removably attached to various surfaces of test and measurement tools. An imaging tool comprising a sensor array capable of receiving electromagnetic radiation from a target scene can be configured to engage a surface of the test and measurement tool such that the imaging tool is supported by the test and measurement tool. When the imaging tool is engaged with the test and measurement tool, the sensor array can be movable relative to the imaging tool so that a target scene viewed by the sensor array of the imaging tool is adjustable without requiring movement of the test and measurement tool.
Abstract:
A spectroscopic module 1 is provided with a spectroscopic unit 8 and a photodetector 9 in addition to a spectroscopic unit 7 and a photodetector 4 and thus can enhance its detection sensitivity for light in a wide wavelength range or different wavelength regions of light. A light-transmitting hole 4b is disposed between light detecting portions 4a, 9a, while a reflection unit 6 is provided so as to oppose a region R in a light-absorbing substrate 2, whereby the size can be kept from becoming larger. Ambient light La is absorbed by the region R in the substrate 2. Any part of the light La transmitted through the region R in the substrate 2 is reflected to the region R by the unit 6 formed so as to oppose the region R, whereby stray light can be inhibited from being caused by the incidence of the light La.
Abstract:
A spectroscopic sensor 1A comprises an interference filter unit 20A having a cavity layer 21 and first and second mirror layers 22, 23 and a light detection substrate 30 having a light-receiving surface 32a for receiving light transmitted through the interference filter unit 20A. The interference filter unit 20A has a first filter region 24 corresponding to the light-receiving surface 32a and a ring-shaped second filter region 25 surrounding the first filter region 24. The distance between the first and second mirror layers 22, 23 varies in the first filter region 24 and is fixed in the second filter region 25.
Abstract:
Color calibration of color image rendering devices, such as large color displays, which operate by either projection or emission of images, utilize internal color measurement instrument or external color measurement modules locatable on a wall or speaker. A dual use camera is provided for a portable or laptop computer, or a cellular phone, handset, personal digital assistant or other handheld device with a digital camera, in which one of the camera or a display is movable with respect to the other to enable the camera in a first mode to capture images of the display for enabling calibration of the display, and in a second mode for capturing image other than of the display. The displays may represent rendering devices for enabling virtual proofing in a network, or may be part of stand-alone systems and apparatuses for color calibration. Improved calibration is also provided for sensing and correcting for non-uniformities of rendering devices, such as color displays, printer, presses, or other color image rendering device.
Abstract:
An apparatus includes a three dimensional array of light receptors disposed within a substrate having a light receiving surface, where light receptors disposed closer to the light receiving surface are responsive to light having shorter wavelengths than light receptors disposed further from the light receiving surface, and where each light receptor is configured to output a binary value and to change state between an off-state and an on-state by the absorption of at least one photon.
Abstract:
A spectroscopy system includes an array of quantum cascade lasers (QCLs) that emits an array of non-coincident laser beams. A lens array coupled to the QCL array substantially collimates the laser beams, which propagate along parallel optical axes towards a sample. The beams remain substantially collimated over the lens array's working distance, but may diverge when propagating over longer distances. The collimated, parallel beams may be directed to/through the sample, which may be within a sample cell, flow cell, multipass spectroscopic absorption cell, or other suitable holder. Alternatively, the beams may be focused to a point on, near, or within the target using a telescope or other suitable optical element(s). When focused, however, the beams remain non-coincident; they simply intersect at the focal point. The target transmits, reflects, and/or scatters this incident light to a detector, which transduces the detected radiation into an electrical signal representative of the target's absorption or emission spectrum.
