Abstract: An apparatus having a variable angle light source characterized by a pivot point, a variable response optical receiver, and a first optical system is disclosed. The variable response optical receiver receives light generated by the light source on a receiving surface, the receiver generating a signal indicative of an intensity of light that impinges on a receiving surface. The first optical system images the pivot point to a fixed point relative to the receiver surface. In one aspect of the invention the first optical system is chosen such that light from the variable angle light source covers mores than half the receiving surface. The variable angle light source can include a gain chip in a semiconductor laser having a pivot point located substantially on a facet of the gain chip.
