In this paper, we use the irradiance transport equation and the Fourier transform-based experimental solution given by Ichikawa-Lohmann-Takeda. We analyze experimental factors such as the digital filter, the introduced error for the rotation and period of the Ronchi ruling, and a new method is demonstrated for the measurement of 3D wavefront information.

Measurement of aspheric and freeform surfaces remains challenging due to the various shapes of the surface under test (SUT), especially when the SUT has a large aperture and strong deviation from the ...
This Letter presents the first complete six dimensional phase space measurement of a beam in an accelerator. The measurement was made on the Spallation Neutron Source Beam Test Facility. The data reve...
Three-dimensional (3D) imaging offers new opportunities to enable objective and quantitative analysis of the breast. Unlike scanning of rigid objects, respiration may be one of the factors that can in...
This paper introduces a structured light system with two projectors and one camera for three-dimensional (3D) shape measurement to alleviate problems created by a single projector such as the shadow p...
The in-line characterization of freeform optical elements during the production cycle is challenging. Recently, we presented a compact sensor setup for the characterization of the wavefront generated ...
Development of reliable and objective evaluation methods is required for natural upper-extremity tasks. Three-dimensional imaging measurement techniques are a powerful tool for quantitativ...
The aim of the study to evaluate Five-Dimensional Ultrasound in automated measurement of ovarian follicles with controlled ovarian stimulation in contrast to the conventional 2D ultrasound
The purpose of this study is to assess the bioavailability of dexlansoprazole from a 30 milligram (mg) or 60 mg delayed-release capsule manufactured at Takeda GmbH Plant Oranienburg, Germa...
Ultrasound imaging (US), a radiation-free imaging modality, is currently used in diagnosis of developmental dysplasia of the hip (DDH) in infants. The current protocol involves manually id...
The purpose of the study to evaluate Five-Dimensional Ultrasound in automated measurement of the fetal femur length at third trimester of pregnancy.
The closeness of a determined value of a physical dimension to the actual value.
Methods for performing three-dimensional measurement and motion analysis using stereoscopic radiographs.
Echocardiography amplified by the addition of depth to the conventional two-dimensional ECHOCARDIOGRAPHY visualizing only the length and width of the heart. Three-dimensional ultrasound imaging was first described in 1961 but its application to echocardiography did not take place until 1974. (Mayo Clin Proc 1993;68:221-40)
The process of generating three-dimensional images by electronic, photographic, or other methods. For example, three-dimensional images can be generated by assembling multiple tomographic images with the aid of a computer, while photographic 3-D images (HOLOGRAPHY) can be made by exposing film to the interference pattern created when two laser light sources shine on an object.
Measurement of intracardiac blood flow using an M-mode and/or two-dimensional (2-D) echocardiogram while simultaneously recording the spectrum of the audible Doppler signal (e.g., velocity, direction, amplitude, intensity, timing) reflected from the moving column of red blood cells.
