Abstract: There is provided an object tracker comprising: a first waveguide; a source of illumination light; a detector optically coupled to said waveguide; and at least one grating lamina formed within said waveguide. Illumination light propagating along a first optical path from said source to an object in relative motion to the object tracker. Image light reflected from at least one surface of an object is deflected by said grating lamina into a second optical path towards said detector.
