Abstract: A lighting device (100) is suitable for adjusting a light colour with respect to elements contained within an output field, separately for each element. The lighting device comprises at least two light systems (1a-1d) each adapted for operating as a light detector and also as a light source, a scanning system (2) suitable for scanning the output field, and a processing unit (3). Such lighting device is especially adapted for exhibiting articles with producing enhanced appeal to an observer. To this purpose, light which is directed towards each element may be enhanced in saturation and brightness as compared to initial light reflected by the element, while hue may be substantially maintained.

Abstract: An active imaging system, which includes a light source and light sensor, generates structured illumination. The light sensor captures transient light response data regarding reflections of light emitted by the light source. The transient light response data is wavelength-resolved. One or more processors process the transient light response data and data regarding the structured illumination to calculate a reflectance spectra map of an occluded surface. The processors also compute a 3D geometry of the occluded surface.

Abstract: Methods and optical detection systems (200, 300, 800, 900) for generating and processing a real-time time-domain cavity ringdown spectroscopy (CRDS) signal (831, 931) from an absorbing species in an optical detection system (200, 300, 800, 900) having an optical ringdown cavity (200, 300) are disclosed. The optical ringdown cavity (200, 300) is adapted for accepting a sample of an absorbing species. One or more modulated light signals (241,243,245,341) are generated using one or more light sources (240, 242, 244, 340). The light source(s) (240, 242, 244, 340) is pulsed at a specified pulse rate(s). The modulated light signal(s) (241,243,245, 341) is resonated using the optical ringdown cavity (200, 300) comprising a plurality of mirrors (220, 230), or sets of mirrors (320, 330), to produce the CRDS signal (831, 931). The reflectivity of the mirrors (220, 230), or sets of mirrors (320, 330), is dependent upon the pulse rate of the modulated light signals (241,243,245,341). Different beamlines (212, 214, 216, 312, 314, 316) are established by the modulated light signal(s) (241,243,245, 341) and the mirrors (220, 230, 320, 330) interacting with the absorbing species sample.

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.

Abstract: An optical system comprising a light source comprising a plurality of light emitting elements (LEEs) is presented. The light source is mounted on the same substrate or chip board so that the LEEs are in thermal contact with each other such as to enable thermic conduction and heat transfer between the LEEs. The system is switchable between light source modes in which different light emitting elements or a different number of light emitting elements is switched in an on mode and in a down mode respectively. In all light source modes, one or more light emitting elements, such as those with longer expected lifetime, remain in the on mode, while one or more light emitting elements, such as those with shorter expected lifetime, may be switched in the down mode.

Abstract: A method and a system for measuring an optical asynchronous sample signal. The system for measuring an optical asynchronous sampling signal comprises a pulsed optical source capable of emitting two optical pulse sequences with different repetition frequencies, a signal optical path, a reference optical path, and a detection device. Since the optical asynchronous sampling signal can be measured by merely using one pulsed optical source, the complexity and cost of the system are reduced. A multi-frequency optical comb system using the pulsed optical source and a method for implementing the multi-frequency optical comb are further disclosed.
