Abstract: An imaging system (200) for generating a measure of authenticity of an object (10) comprises a dispersive imaging arrangement (30) and an image sensor arrangement (60). They are positioned so that, when electromagnetic radiation (20) from the object (10) illuminates the dispersive imaging arrangement (30), the electromagnetic radiation is dispersed and imaged by the image sensor arrangement (60). The imaging system (200) is configured to then generate a measure of authenticity of the object (10) depending at least on a relation between the imaged dispersed electromagnetic radiation and reference spectral information. The invention also relates to imaging methods, computer programs, computer program products, and storage mediums.

Abstract: Systems and methods are provided for measuring spectral hemispherical reflectance. One embodiment is a system that includes a laser that emits a beam of light, and an optical chopper disposed between the laser and a sample. The chopper blocks the beam while the chopper is at a first angle of rotation, redirects the beam along a reference path while the chopper is at a second angle of rotation, and permits the beam to follow a sample path through the chopper and strike the sample while the chopper is at a third angle of rotation. The system also includes a hollow sphere that defines a slot through which the sample path and reference path enter the sphere. The hollow sphere includes a spectral hemispherical reflectance detector, a mount that receives the sample at the sphere, and an actuator that rotates the sphere about an axis that intersects the sample.

Abstract: The invention features devices and methods for collecting and measuring light from external light sources. In general, the devices of the invention feature a light diffusing element, e.g., as a component of a light collector, connected by a light conducting conduit, e.g., a fiber optic cable, to a light measuring device, e.g., a spectrometer. This light diffusing element allows, e.g., for substantially uniform light diffusion across its surface and thus accurate measurements, while permitting the total footprint of the device to remain relatively small and portable. This light diffusing element also allows flexibility in scaling of the device to permit use in a wide range of applications.

Abstract: A system to provide radiant energy of selectable spectral characteristic (e.g. a selectable color combination) uses an integrating cavity to combine energy of different wavelengths from different sources. The cavity has a diffusely reflective interior surface and an aperture for allowing emission of combined radiant energy. Sources of radiant energy of different wavelengths, typically different-color LEDs, supply radiant energy into the interior of the integrating cavity. In the examples, the points of entry of the energy into the cavity typically are located so that they are not directly visible through the aperture. The cavity effectively integrates the energy of different wavelengths, so that the combined radiant energy emitted through the aperture includes the radiant energy of the various wavelengths. The apparatus also includes a control circuit coupled to the sources for establishing output intensity of radiant energy of each of the sources. Control of the intensity of emission of the sources sets the amount of each wavelength of energy in the combined output and thus determines a spectral characteristic of the radiant energy output through the aperture.
