Abstract: According to one aspect of the disclosure, a lighting system comprises a remote control unit (4) and at least one lighting device (2a, 2b, 2c) comprising a light driver (13) and a light emitter (14). The remote control unit (4) comprises an image capturing unit (5) and is arranged to control the lighting device (2a, 2b, 2c). To do so, the remote control unit (4) receives information relating to current/present settings of the image capturing unit (5), then determines one or more properties of signals for visible light communications based on these settings. The one or more properties are then communicated to the at least one lighting device (2a, 2b, 2c). Upon reception thereof the light driver (13) generates a light emitting control signal based on the received properties and visible light communications based on the light emitting control signal is emitted by the light emitter (14). According to another aspect, a lighting device (2a, 2b, 2c) adapts emitted modulated light and adapts the modulation so as not to correspond to blind-spots of an image capture unit (5).

Abstract: A system for determining a distance to an object comprises an image capture device (101) which has a coded aperture and an image sensor which is positioned out of a focus plane of the coded aperture. A receiver (103) receives an image of a scene from the image sensor and a detector (105) detects at least two image objects of the image corresponding to ghost images of the object resulting from different openings of the coded aperture in response to an optical characteristic of the object. A distance estimator (107) then determines a distance to the object in response to a displacement in the image of the at least two image objects. The distance may be to a person and the image may be a bright pupil image wherein pupils are enhanced by reflection of light by the retina. The image may be compensated by a dark pupil image of the scene.

Abstract: The possibility to emit and detect coded light, whereby data is modulated into the light, is known. According to one aspect of the present disclosure, to reduce the risk of the modulation going undetected due to possible frequency blind spots in the detection spectrum, the lighting device (2a, 2b, 2c) is arranged such that the frequency of its emitted modulated light (3a, 3b, 3c) shivers around a base, or center, frequency. For example the modulated light (3a, 3b, 3c) may be transmitted using pulse-width-modulation, and the resulting pulse-width-modulation light signal (3a, 3b, 3c) may thus have a period that fluctuates around the base period (T). The parameters determining the shivering of the modulated light (3a, 3b, 3c) may be chosen such that visible flicker in the emitted modulated light (3a, 3b, 3c) is avoided. According to another aspect, the lighting device (2a, 2b, 2c) emits with a plurality of different modulation frequencies simultaneously.

Abstract: An apparatus for determining a propagation velocity for a surface wave comprises a coherent light source (105) for generating at least a first and a second light spot on a surface (103). A camera (111) captures at least one out-of-focus image of at least a part of the surface (103) comprising the light spots. The out-of-focus image comprises light spot image objects for the light spots where the light spot image objects have speckle patterns. An analyzer (113) determines the propagation velocity in response to a time difference between speckle pattern changes in the two speckle patterns. The camera may specifically use a rolling shutter allowing the determination of the propagation velocity to be based on a spatial analysis of the speckle patterns. The approach may in particular allow an efficient remote measuring of pulse wave velocities e.g. in animal tissue and in particular, in human tissue.
