Paper Abstract

Influence of illuminating beam Gauss parameter to Biological Compact Disc Sensor (BioCD) is presented in this paper. BioCD is a sensitive Interferometry detection platform to detect bimolecular immobilized on the surface of a spinning disk. Interferometry has the advantage of higher photon fluxes than conventional fluorescence detection and consequently shorter detection time. It allows high speed detection of optical path length changes down to sub-nanometer scales with high repeatability. The influences of illuminating beam Gauss parameter to detection sensitivity were simulated. Simulation result showed that Gauss parameter increase will reduce detection sensitivity. But if there is a pinhole filter in optical system Gauss parameter influence could be ignored. This also will be help to Suppression influence of lens aberration, so improve BioCD detection sensitivity.
