Abstract
An optical signal data transceiver comprises a convex mirror to direct received optical signals onto at least one detector responsive to corresponding optical wavelengths. At least one optical emitter is arranged to irradiate the convex mirror such that the emitted optical radiation is reflected from the convex mirror in a diffuse manner. The specific shape of the convex mirror is selected to obtain a desired transmission and reception specificity and suitable shapes include, as non limiting examples, segments of spheres, hemispheres, paraboloids of revolution, right cones, etc.
