Wound assessment by 3-dimensional laser scanning.

in general, DIA provides a technology that can at least partially overcome these problems. Finally, it is important to note that DIA provides information beyond the quantitative evaluation of traditional manual tracings. Because DIA involves digital photography, it provides an image and thus a basis for objective evaluation of other end points such as infection, lesion thickness, granulation st...

Improving solid freeform fabrication by laser-based additive manufacturing

Solid freeform fabrication (SFF) methods for metal part building, such as three-dimensional laser cladding, are generally less stable and less repeatable than other rapid prototyping methods. A large number of parameters govern the three-dimensional laser cladding process. These parameters are sensitive to the environmental variations, and they also in ̄uence each other. This paper introduces th...

Fabrication of Freeform Optics

Freeform surfaces on optical components have become an important design tool for optical designers. Non-rotationally symmetric optical surfaces have made solving complex optical problems easier. The manufacturing and testing of these surfaces has been the technical hurdle in freeform optic’s wide-spread use. Computer Numerically Controlled (CNC) optics manufacturing technology has made the fabr...

Three dimensional microstructuring of biopolymers by femtosecond laser irradiation

A sequence of single femtosecond pulses is used to create a pattern of laser affected spots at increasing depths below the surface of transparent biopolymer samples. Materials with different water contents and mechanical strengths, gelatine, chitosan, synthetic polyvinyl pyrrolidone, and biopolymer-polymer blends, are irradiated near the edge of the sample with an amplified Titanium:Sapphire la...
