Abstract

Based on floating point DSP (TMS320C6748) processor

we design a dark field image processing system in real time

with discussing the theory and the design method and providing the implementation of the system. On this basis

we make experiments of dark field images acquisition and analysis on gold nanospheres. Stepper motor controls the optical grating rotation of dark field

matching the successive acquisition of dark-field images; Simultaneously

CMOS camera acquires the images

which to be processed by DSP

and then we get the scattering spectra of sample. The experiments show that scattering spectra of gold nanospheres consists with the actual spectral properties of gold nanospheres and the functions and properties of the system reach the expectations.The image processing system accomplishes the real-time processing feature of dark field image

which has great application value on detection of early Tumor

heavy metals

chemical and biological and other fields.
