Abstract
Contemporary methods for minimally invasive interventions are gaining
wide acceptance in various everyday operations, offering extremely
localised treatment, reduced suffering and practically no risk for the
patient as well as great benefits to diagnostic examinations and
surgeries that require continuous monitoring. Many established endoscope
systems offer the aforementioned advantages without the risks and
restrictions of the computer-aided tomography techniques but with
limitations in the resolution and chromatic representation provided. A
microscanning specific-endoscope device has been developed aiming to
provide superior resolution and chromatic representation in comparison
with the above endoscopes. The key technology employed in the design of
this endoscope relies on the use of tinny microelectro-mechanical
silicon mirrors for the scanning of three laser beams over the target
tissue area. The so-developed microscanning endoscope system provides
color imaging with high resolution at near video rates targeting at
macroendoscopy applications. The optical design and implementation of
this endoscope system will be presented in this communication together
with a brief description of the overall endoscope device developed. In
addition results are given from the study of the metamery effect,that is
utilised in the realised endoscope, together with a presentation of the
procedure followed for the objective evaluation of its optical
performance and first results from system operation.
