Swept Volumes
Given a solid S ⊂ R with a piecewise smooth boundary, we compute an approximation of the boundary surface of the volume which is swept by S under a smooth one-parameter motion. Using knowledge from kinematical and elementary differential geometry, the algorithm computes a set of points plus surface normals from the envelope surface. A study of the evolution speed of the so called characteristic...
متن کاملFrequency comb swept lasers.
We demonstrate a frequency comb (FC) swept laser and a frequency comb Fourier domain mode locked (FC-FDML) laser for applications in optical coherence tomography (OCT). The fiber-based FC swept lasers operate at a sweep rate of 1kHz and 120kHz, respectively over a 135nm tuning range centered at 1310nm with average output powers of 50mW. A 25GHz free spectral range frequency comb filter in the s...
متن کاملImage-Swept Volumes
Many graphical objects can be represented by swept volumes (including its subset – generalised cylinders) by sweeping 2D or 3D templates along 3D trajectories. In this paper, we present a new approach for constructing swept volumes using image templates. We utilise scalar fields as our underlying data type, and employ volume ray casting techniques for rendering swept volumes in their original s...
متن کاملSwept Wavelength Testing:
In a swept-wavelength measurement system, the wavelength of a tunable laser source (TLS) is swept continuously at a constant rate throughout the desired tuning range, while the device under test (DUT) is monitored simultaneously for its wavelength-dependent optical properties. Given an ideal continuously tunable laser – one that does not exhibit any discontinuities in wavelength, or sudden chan...
متن کاملComputing swept volumes
The swept volume problem is practical, dif®cult and interesting enough to have received a great deal of attention over the years, and the literature contains much discussion of methods for computing swept volumes in many situations. The method presented here permits an arbitrary polyhedral object (given in a typical boundary representation) to be swept through an arbitrary trajectory. A polyhed...
