Abstract
A novel optical-readout for uncooled infrared (IR) focal-plane array thermal imaging system using bi-material cantilever microstructure is studied. The temperature distribution of IR source is obtained on the basis of measurement of the distribution of thermal deformation in the bi-material cantilever microstructure having a large difference in coefficients of thermal expansion. Gray-scale morphology is advanced and applied to IR image pretreatment according to the infrared image with low contrast, blurred and high noise. Gray-scale morphologic open and close operation is used in smooth filtering. Filling the holes on the thermal images is achieved with morphological reconstruction. This method can effectively remove the noise, enhance image mean grads and improve image visual effect.
