Abstract
A method for fabricating a detector or light guide using laser technology. The method yields a detector component such as a scintillator, light guide or optical sensor which provides for the internal manipulation of light waves via the strategic formation of micro-voids to enhance control and collection of scintillation light, allowing for accurate decoding of the impinging radiation. The method uses laser technology to create micro-voids within a target media to optically segment the media. The micro-voids are positioned to define optical boundaries of the optically-segmented portions forming virtual resolution elements within the scintillator. Each micro-void is formed at its selected location using a laser source. The laser source generates and focuses a beam of light into the target media sequentially to form the micro-voids. The laser beam ablates the media at the focal point, thereby yielding the micro-void.
