A multi-function opto-electronic detection apparatus for detecting molecular characteristics of a test sample. The appratuses comprises functional mode subsystems including a detecting light source subsystem for generating sampling beams for illuminating the test sample; a manipulation optics subsystem for aligning the sampling beam onto the test sample; a target signal processing subsystem for analyzing target beams emerging from the test sample resulting from the illuminating of the sampling beam; and a sample fixation subsystem for holding the test sample. The detecting light source subsystem, manipulation optics subsystem and target signal processing subsystem are assembled into one of several possible optical sampling setups for the detection characteristics of the test sample. The functional mode setups include at least ellispometer, confocal image scanner, photon tunneling scanning microscope and interferometer.

A polarization splitting backlight module for efficiently converting a non-polarized light beam emitted from the light source into a single polarization state is disclosed. The polarization splitting backlight module of the present invention comprises an under plate with a ridged lower surface, a light source, a special reflection film, a scattering structure, a substrate and a polarization splitting film. The light beam emitted from the light source is introduced into the scattering structure between the under plate and the substrate. After a series of processes, such as scattering, reflection, phase retardation and polarization beam-splitting, the light beam will pass through the polarization splitting film being of a single polarization state such that it could be utilized by electro-optical systems, such as liquid crystal displays. The present invention converts light beams into a single polarization state, and the efficiency thus is higher than that of a conventional backlight module. The present invention achieves brightness levels that are almost twice that of conventional backlight module.

A method and apparatus is claimed for measuring the distance between a slider and a transparent disk with sub-nanometer resolution. The flying height is measured by applying ellipsometry. The measurement is done by: providing a sampling light beam with adjustable initial polarization state by phase modulation, and with variable incident angles relative to the air film and reflecting the sampling light off of the specimen at a detection site forming a reflected light beam that is then reflected at the detection site again and then guided to both detectors for detecting the intensity and phase change of the light beam to determine the gap's thickness as well as passing some light to a microscope used for observation of the detecting site on the specimen.
