Light with reflector or diffuser screen
The invention relates to a light (1) comprising a housing (2) with at least one illuminant (8) and an illuminant holder (9). In order to enable a targeted light emission and hence illumination of a particular region, the housing (2) has a translucent housing element (3), which can be covered at least partially by at least one moveable screen (4, 5) and thus limits the emission angle..

Optical coherence tomography systems and methods
An optical coherence tomography system may have a reflector system that reflects light from a light source to provide a plurality of light rays that fall within different wavelength ranges, optical componentry that directs a subset of a first beam of light including the plurality of light rays to an object to be imaged, a detector that detects the subset after reflection from the object, and signal processing componentry that processes signals from the detector to provide an optical coherence tomography image of the object. The reflector system may be configured such that the optical pathways followed by the light rays change in length at an even increment, so that the first beam of light will project wavelength groups at relatively even time increments.
