dc.description.abstract | A chromatic confocal microscopic profilometer for full-field three-dimensional
micro surface measurement was developed using innovative multi-wavelength light correlation. Micro/nano structures patterned on the substrate and fabricated by the R2R (Roll-to-Roll) nanoimprint processes are usually having a smooth and low-reflective surface which is not easily measured by the existing optical or contacted methods. It was an extremely difficult task to achieve an effective 3-D profile reconstruction on this kind of micro component by using a traditional confocal microscope. In this paper, a multi-wavelength confocal measurement method employing the focusing cross correlation between three LED color (Red, Green and Blue) lights was introduced to measure micro structures. A compact chromatic confocal microscopic probe was developed by integrating a white light source obtained by mixing the LED light sources and a coaxial confocal optical configuration with a 3-chip CCD camera for individual light sensing. A curve-fitting function between the profile depth and the multi-color focusing correlation was established by a system calibration with a reference to an accurate laser interferometer. To attest the measurement performance, a calibrated reference target having micro-triangular structures was fabricated and measured by the developed methodology. From analysis of the measurement results, it was confirmed that a standard deviation of 30 nm on the height measurement can be achieved. The confocal profilometer can be effectively employed to the automatic optical inspection (AOI) task of the brightness e n h a n c eme n t f i lms ( BE F ) f a b r i c a t e d b y t h e R 2R p r o c e s s e s . | en |
