    Abstract: An apparatus for detecting a pointer within a region of interest includes a first reflective element extending along a first side of the region of interest and reflecting light towards the region of interest. A second reflective element extends along a second side of the region of interest and reflects light towards the region of interest. The second side is joined to the first side to define a first corner. A non-reflective region generally in the plane of at least one of the first and second reflective elements is adjacent the first corner. At least one imaging device captures images of the region of interest including reflections from the first and second reflective elements.

    Abstract: A variable-intensity, wide-angle illuminator is disclosed, one embodiment comprising: a light source for providing a light beam; an optical cable, optically coupled to the light source for receiving and transmitting the light beam; a handpiece, operably coupled to the optical cable to receive the light beam; an optical fiber, operably coupled to the handpiece, wherein the optical fiber is optically coupled to the optical cable to receive and transmit the light beam; an optical element, optically coupled to a distal end of the optical fiber, for receiving the light beam and scattering the light beam to illuminate a surgical field, wherein the optical element comprises: a polymer matrix; and a plurality of microbubbles displaced within the polymer matrix; and a cannula, operably coupled to the handpiece, for housing and directing the optical fiber and the optical element. The optical element can be a small-gauge, diffusive optical element having circular or semi-ellipsoidal incident surfaces. For example, the optical element can be a 19, 20 or 25 gauge optical element. Further, the optical element, the cannula and the handpiece can be fabricated from biocompatible materials. The optical cable can comprise a first optical connector operably coupled to the light source and a second optical connector operably coupled to the handpiece (to optically couple the optical cable to the optical fiber housed within the handpiece and cannula).
