Monitoring is an essential requirement for the planning, assessment and evaluation of conservation measures. It should be based on a standardized and reproducible observation of the historical surface...
A case example for laser data treatment to study rocky faces with protection barriers
Photogrammetry LIDAR, Surveying Environment Application
2015/8/25
LIDAR is a useful technique for natural and architectural metric surveying.Acquisition is the first step in laser surveying. The second step is the data treatment that is necessary to obtain a correct...
Influence of PbX2 (X = F, Cl, Br) content and thermal treatment on structure and optical properties of lead borate glasses doped with rare earth ions
lead borate glasses rare earth ions thermal treatment luminescence, up-conversion
2011/5/6
Oxyhalide lead borate glasses doped with rare earth ions have been studied before and after thermal
treatment. The rare earths as optically active ions were limited to the Er3+ ions. Near-infrared
l...
The influence of thermal treatment of the porous glass plates on the character of their scattering in visible spectral region
phase-separated alkali borosilicate glasses porous glass light transmission
2011/5/6
The pore structure and light transmission of the high-silica porous glasses in visible spectral
region are investigated depending on a temperature of their thermal treatment and composition of
the i...
Thermal treatment effect on dynamics of luminescent states in oxyfluoride glass-ceramics doped with Pr3+ and Tb3+
oxyfluoride glasses differential thermal analysis thermal treatment optical properties luminescence dynamics lifetimes
2011/5/6
The 50GeO2–(50–x–y)PbO–yPbF2–xLnF3 glass single doped with Pr3+ and Tb3+ ions was
studied. The composition of the material was modified by varying the content of both PbF2 ( y = 5,
10, 15 mol%) and ...
The application of excimer laser to polyethylene-terephthalate fiber (PET) and aramid fiber is investigated, from a viewpoint of “ablation”. First, the ablation mechanism of these fibers were revealed...
Treatment of Corneal Diseases or Refractive Errors with Laser Processing
Excimer laser Refractive surgery Vision
2009/6/8
Using the ArF excimer laser to alter corneal tissue is now applicable to the field of ophthalmology. For the treatment of corneal scarring or corneal dystrophy, phototherapeutic keratectomy (PTK) may ...
A Proposed Method for Thermal Specific Bioimaging and Therapy Technique for Diagnosis and Treatment of Malignant Tumors by Using Magnetic Nanoparticles
Thermal Specific Bioimaging Therapy Technique Malignant Tumors Magnetic Nanoparticles
2009/5/19
The objective of this research program is to develop a novel, noninvasive, low-cost infrared (8–12 μm spectral range) imaging technique that would improve upon current methods using nanostructur...
