For early detection of abnormalities growing within the healthy tissues a laser based multi-slice reflectance measurement
technique is developed. The laser light is guided at the center of the probe. Around this the photo-detectors are arranged
symmetrically at various distances from the beam entry point. The optical radiations after scattering within the tissue
emerge at various locations which are detected by the detectors. After conversion from current to voltage these signals
are digitized and fed to computer. After pre-processing of the backscattered signals from 36 photo-detectors arriving
from various locations the reflectance images are reconstructed. As the detectors are placed at various distances from the
beam entry point in the form of rings, their respective images are obtained. These multi-slices images provide variation
in composition at various depths ranging from 2 - 7.5mm. Thus by placing the probe just once the required data for
images reconstruction is obtained. This is in contrast to earlier developments as this does not involve the movement of
the probe for image reconstruction. Based on the sequence of images from various depths a three - D image of the tissue
structure could also be obtained.
