White light microscope interferometry is an optical, noncontact and quick method for measuring the topography of surfaces. It is shown how the method can be applied toward mechanical wear analysis, where wear scars on tribological test samples are analyzed; and in materials science to determine ion beam sputtering or laser ablation volumes and depths.

Laparoscopy-endoscopy cooperative surgery is appropriate for the treatment of gastric gastrointestinal stromal tumors less than 5 cm in size. It can achieve the respective advantages of endoscopic and laparoscopic surgeries while avoiding their drawbacks.
FAQs
Illumination and image formation operate as a continuous optical chain. Visible light travels through optical fibers or comes from an electronic source, reaches the mucosal surface, and returns as reflected information. Lenses collect and transmit that information to a camera or display, allowing clinicians to interpret anatomy and abnormalities during the examination rather than from delayed images.
White-light imaging provides the essential reference view for examining hollow organs, identifying abnormalities, and guiding clinical decisions. Newer imaging modes may enhance subtle features, but they do not replace the standard examination’s role in screening, diagnosis, and follow-up. Maintaining this baseline also allows clinicians to compare enhanced observations with the primary visible appearance of the mucosa.
Real-time reflected images allow clinicians to inspect the mucosa for visible abnormalities such as inflammation, ulcers, bleeding, polyps, and tumors. When a suspicious or clinically relevant area appears, the endoscopic view can guide a targeted biopsy rather than relying on an undirected sample. This links visual examination with tissue-based diagnostic evaluation.
Flexible and rigid endoscopes provide different instrument formats for examining inner surfaces, while both can deliver illumination and transmit the resulting image. Their optical components support visualization through lenses, optical fibers, or an electronic light source, depending on the system. The selected format therefore remains part of how clinicians obtain and display real-time mucosal views.
The examination begins by delivering visible illumination to the inner surface of a hollow organ and displaying the reflected image in real time. Clinicians then inspect the mucosa for abnormalities, document findings through the endoscopic view, and decide whether further action is appropriate. Supported actions include targeted biopsy, lesion removal, or hemostasis when indicated by the observed finding.
Its uses extend across screening, diagnostic examination, treatment, and follow-up. The same baseline view can help identify lesions or other abnormalities, monitor previously recognized disease, and support procedures performed during examination. Because it displays the mucosa in real time, clinicians can connect visual findings with immediate decisions about sampling, lesion removal, or control of bleeding.
The technique does more than reveal abnormalities because its real-time view can guide interventions at the observed site. Clinicians may use the image to direct targeted biopsies, remove a lesion, or perform hemostasis, meaning control of bleeding. This integration of visualization and treatment makes the examination useful when diagnosis and management need to occur in the same procedure.
