OPEN ACCESS
The paper is devoted to modern diagnostic methods: based on utilization of the detectable effects of light–tissue interaction. Transillumination is a method of object examination by the passage of light through tissues or a body cavity. Under the transillumination and illumination from underneath, it is possible to diagnose and monitor the parameters of tissues and organs examined. The authors briefl y report the current state in the art as well as present their own results. Among other things, the presented examples include: optoelectronic techniques used in monitoring of the living tissues vitality and promising results obtained during preliminary experiments with transillumination scanning applied to human hand fi ngers. Upon the test results analysis, the necessity arises to confi gure the optical part so that a better resolution can be obtained with capacity of effective transillumination of objects optically thicker.
