Abstract

A diagnostic system for support of laser ocular surgery, for example, solves a problem of competition for light which is often encountered when a series of different detectors are used to receive and detect features of a target reflecting an illuminating light beam. The intensity of an illuminating beam, particularly in eye surgery, is limited to a level above which damage to the eye can occur. In a system wherein a plurality of successive beam splitters are used, each reflecting a portion of the light intensity and transmitting the remaining light intensity, the series of detecting devices compete for adequate light intensity for the particular functions being served. The system of the invention solves this problem and increases the effective quantity of light useful from a given input intensity by dividing the light spectrally after its reflection from the eye, thereby making use of a different spectral range of the light at each of the plurality of different detecting devices.
