Digital spatially incoherent Fresnel holography.
We present a new method for recording digital holograms under incoherent illumination. Light is reflected from a 3D object, propagates through a diffractive optical element (DOE), and is recorded by a digital camera. Three holograms are recorded sequentially, each for a different phase factor of the DOE. The three holograms are superposed in the computer, such that the result is a complex-value...

متن کاملThe Feathered Clarinet Reed
In this research, a method previously applied to improve a digital simulation of the avian syrinx is adapted to the geometry of the clarinet reed. The clarinet model is studied with particular attention to the case when the reed beats again the lay of the mouthpiece, closing off air flow to the bore once each period. In place of the standard reed table which gives steady-state volume flow as a ...
متن کاملEstimating the Reed Pulse from Clarinet Recordings
In this work we estimate the volume flow pulses through a clarinet reed from recorded clarinet signal. The idea is similar to extracting glottal pulse sequences from recorded speech, however since the clarinet reed has little mass and generates significant reflection, the source-filter model used in speech processing invalid. Here, the clarinet is modeled as a pressure-controlled valve coupled ...
متن کاملImaging analysis of digital holography.
In this study we focus on understanding the system imaging mechanisms given rise to the unique characteristic of discretization in digital holography. Imaging analysis with respect to the system geometries is investigated and the corresponding requirements for reliable holographic imaging are specified. In addition, the imaging capacity of a digital holographic system is analyzed in terms of sp...
