General solution for high dynamic range three-dimensional shape measurement using the fringe projection technique
This paper presents a general solution for realizing high dynamic range three-dimensional (3-D) shape measurement based on fringe projection. Three concrete techniques are involved in the solution for measuring object with large range of reflectivity (LRR) or one with shiny specular surface. For the first technique, the measured surface reflectivities are sub-divided into several groups based o...
متن کاملHigh-Dynamic-Range Laser Amplitude and Phase Noise Measurement Techniques
We describe techniques for making sensitive and high-dynamic-range measurements of laser amplitude and envelope phase noise (timing jitter) in the frequency domain at the shot-noise limit. Examples of amplitude noise measurements on continuous-wave argon-ion and diode-pumped solid-state lasers used for pumping a femtosecond Ti : sapphire laser are presented. Amplitude and phase noise measuremen...

Peisen S. Huang, MEMBER SPIE State University of New York at Stony Brook Department of Mechanical Engineering Stony Brook, New York 11794 Abstract. We describe a high-resolution, real-time 3-D shape measurement system based on a digital fringe projection and phase-shifting technique. It utilizes a single-chip digital light processing projector to project computer-generated fringe patterns onto ...
متن کاملComparison of three different techniques in parotid gland tumors using three dimensional conformal radiation therapy
Introduction: Background: Radiotherapy of parotid tumors is achieved by different radiotherapy techniques. So they deliver the dose to organs at risk such as contralateral parotid, temporal lobe & spinal cord. The consequences of high dose to OARs are xerostomia, Temporal lobe necrosis and loss of hearing. Purpose: The aim of this study was to compare different treatment tech...
