Paper Abstract

Development of high power light-emitting diodes has brought new possibilities in many applications, especially in terms of flexible adjustment of light spectra. This feature is very useful in construction of many devices, for example for medical diagnosis – imaging of biological objects. In the paper we describe exemplary results of imaging of biological samples with the use of the tunable LED-based source. The source is composed of 13 high power light-emitting diodes (11 monochrome and 2 phosphor converted LEDs) covering visible region. The system allows to illuminate the object with quasi-monochromatic light (monochrome LEDs) as well as white light with the possibility of adjusting the color temperature in the range of 2700-6500K. To obtain object images miniature color camera was used which allowed us to test the operation of the source in a model of endoscope. Recorded images were processed in Matlab in order to analyze the RGB channels and test future possibility of automatic detection of selected areas of the tissue.
