Abstract: Systems and methods for filtering an optical beam are described. In one implementation, a system for filtering an input optical beam includes a first beamsplitter, a first spectral slicing module, a second spectral slicing module, and a second beamsplitter. The first beamsplitter is configured to split the input optical beam into a first optical beam and a second optical beam. The first spectral slicing module has a first passband and is configured to filter the first optical beam. The second spectral slicing module has a second passband and is configured to filter the second optical beam. The second beamsplitter is configured to combine the first optical beam and the second optical beam into an output optical beam. The first and second spectral slicing modules may each comprise a longpass filter and a shortpass filter aligned along its optical axis, and the longpass filter and/or the shortpass filter are rotatable relative to the optical axis. Advantageously, the optical system allows for tunable spectral filtering of the input optical beam suitable for 2-D imaging systems.

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: Surface enhanced Raman spectroscopy is employed to obtain chemical data with respect to cells while electrophysiological data relating to cell membranes is obtained using the patch clamp technique. A SERS-facilitating assembly is coupled to a micropipette and is used in conjunction with a monochromatic light source for generating scattered light. Surface enhanced Raman spectroscopy is employed to obtain the chemical data. Electrophysiological data is obtained using the same micropipette to perform the patch clamp technique.

Abstract: Spectrocolorimetric device includes a light source, a light-receiving unit, a calculation unit, a storage unit, an acquisition unit, and a conversion unit. The light-receiving unit spectroscopically disperses reflected light generated on a surface and measures a spectroscopic spectrum relating to the reflected light. The calculation unit calculates a first spectral reflectance from the spectroscopic spectrum. The storage unit stores relationship information indicating a relationship between a reflectance and a reflectance difference for each wavelength. The acquisition unit acquires reflectance difference for each wavelength between the first spectral reflectance acquired using the spectrocolorimetric device and a second spectral reflectance acquired using a destination-of-conversion spectrocolorimetric device on the basis of the first spectral reflectance and the relationship information. The conversion unit converts the first spectral reflectance into the second spectral reflectance by adding or subtracting the reflectance difference for each wavelength acquired by the acquisition unit to or from the first spectral reflectance.

Abstract: A method of spectroscopic analysis of a diamond for determining whether the diamond has been artificially treated to change its colour may include: generating light emission from a diamond upon optical excitation at a wavelength equal to or smaller than 680 nm; optically producing a dispersed light emission; detecting the dispersed light emission across a collected spectral region including emission wavelengths of from 670 nm to 735 nm; processing the output signals to produce a spectral intensity distribution as a function of emission wavelengths; analysing the spectral intensity distribution to determine the presence or absence of a spectral pattern including either an intensity peak at 681 nm or a combination of intensity peaks at respective wavelengths 705 nm and 725 nm; if a spectral pattern is present, establishing that the diamond has been treated; and if a spectral pattern is absent, establishing that the diamond has not been treated.
