Abstract:
Systems and methods of the present disclosure are directed to detecting species within a fluid using a multi-pass absorption cell and a spectrometer. The absorption cell includes a plurality of mirrors arranged in a manner such that a detection light traverses multiple passes through the fluid within the absorption cell. In some implementations, the detection light is reflected by the plurality of mirrors to form optical paths in more than one plane. The system also includes an electronic unit configured to receive and process spectral data from the spectrometer. In some implementations, the electronic unit communicates with at least one computational unit over a communication interface to send a portion of the spectral data for processing. The electronic unit may also receive processed data from the computational unit.
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.

In some embodiments the method comprises: a. performing a plurality of light-scattering measurements upon a sample of hair such that for each light-scattering measurement, the sample of hair is illuminated from a different respective direction; b. comparing the results of the light-scattering measurements; c. in accordance with results of the comparing, computing an initial damage-state of hair of the sample by comparing the results of the light-scattering measurements; d. obtaining an initial color-state of the hair of the sample; and e. computing a hair-coloring composition that is predicted to transform the hair sample from the initial color-state to a target color-state such that in response to a determining of a greater (lesser) extent of initial damage, a concentration of artificial- colorant(s) within the computed coloring composition is reduced (increased).
Abstract:
System and method configured to operate under conditions when the object being imaged destroys or negates the information which otherwise allows the user to take advantage of optical parallax, configured to elicit luminescence from the same targets in the object as a result of irradiation of these targets with pump light at different, respectively corresponding wavelengths, and acquire optical data from so-illuminated targets through the very same optical path to image the object at different wavelengths. One embodiment enables acquisition, by the same optical detector and from the same object, of imaging data that includes a reflectance image and multiple fluorescence-based images caused by light at different wavelengths, to assess difference in depths of locations of targets within the object.

Abstract:
The present invention discloses a moving platform infrared image-spectrum associated detection system, including an optical hood, a broadband optical system, a two-dimensional servo system, an infrared optical fiber, a Fourier interference spectrum module, an image-spectrum associated detection processing module, a power supply module, and a display module. Incident light enters from the optical hood to the broadband optical system, and is split by a spectroscope. Transmitted light is focused by a long-wave imaging lens group on an infrared detector for imaging. Reflected light is focused by a broadband spectrum lens group to an optical fiber coupler, enters the Fourier interference spectrum module through the infrared optical fiber to form an interference pattern, and undergoes Fourier transform to obtain spectral data. The image-spectrum associated detection processing module effectively merges infrared imaging and broadband spectral data, and the two-dimensional servo system is used to control a center orientation of the broadband optical system, thereby implementing target detection, tracking and spectrum measurement in a moving platform condition. The present invention can effectively isolate the system from disturbance of the moving platform, has the capability of simultaneously performing scene imaging, local area spectrum measurement, and multi-target tracking spectrum measurement, has a high speed and an adequate data amount, and has a broad application prospect.
