Abstract:
1. An apparatus for interferometric measurement of a sample, the sample comprising an eye, the apparatus comprising: a short-coherence interferometer arrangement, which comprises a measurement beam path through which a measurement beam is incident on the sample, and a reference beam path, through which a reference beam passes wherein the measurement beam is superimposed on the reference beam and interference occurs between the reference beam and the measurement beam; and a spectrometer arrangement that detects the superimposed beams, said arrangement comprising an element which spectrally spreads the superimposed beams and a detector array which comprises at least 7,000 individual photo-sensitive cells arranged such that two signal peaks are captured in a short period of time, one of the two signal peaks representing an anterior structure and another of the two signal peaks representing a posterior structure and such that eye measurements over a full axial length of the eye are performed in the single measurement over a short period of time.
