Abstract

In the paper a result of hand fingers transillumination is presented. During experiments, an robot arm equipped with an optoelectronic system has been used. The object scanning was realized in the rectangular coordinates system. Optical radiation at the wavelength 880 nm was emitted by a high power LED to be supplied in pulse mode while a photodiode PIN was used as the photodetector. Both light source and photodetector were set into the special diaphragms in order to collect all ballistic photons. The signals obtained from the photodiode allowed determining the object optical attenuation occuring in particualr sites of the transilluminated surface in a form of two-dimensional image. Also selected examples of current modern transillumination applications in medical diagnostics are presented.
