Sentence examples for fringe frequencies from inspiring English sources

In the "long range mode," the reduced sweep range translates into lower fringe frequencies at the same imaging depth.

As a result, image quality and axial resolution degrade rapidly beyond a depth of 10.6mm, as fringe frequencies corresponding to these depths begin to alias.

As smaller fringe periods (i.e. higher fringe frequencies) correspond to deeper imaging depths, this reduced visibility results in decreasing sensitivity with increasing imaging depth.

This range of carrier fringe frequencies was chosen to optimally use the camera's spatial frequency bandwidth for off-axis interferometry [ 9].

Due to the high speed and good coherence, the −6 dB roll-off point corresponds to fringe frequencies above 1 GHz and requires sampling rates in the GS/s range.

In incoherent detection, OTF represents the contrast of the fringe detected at the image plane and is equivalent to the signal generated when a thin sheet of fluorescence is scanned through the focus [ 29]. Figure 3(a) shows the plot of Eq. (7) at the fringe periods of Tg = 3.42µm, 1.71µm, 0.85µm, 0.43µm which correspond to the normalized fringe frequencies of 0.13, 0.26, 0.52, 1.04, respectively.

In contrast to the Mach-Zehnder interferometer, this setup is compact and tunable in fringe frequency.

That is to say, the fringe frequency ratios are 1 1, 1 2, 1 3, and 1 4, respectively.

Using an original numerical simulator of ILIDS images, we propose and discuss the performances of different ILIDS configurations for microscopy, volumic 3D droplet characterization, and fringe frequency calibrations.

This paper presents a method for fringe frequency determination based on the capability of neural networks to recognize signals that are similar but not identical to signals used to train the neural network.

We have designed and fabricated one optical test system with large errors in illumination optics and low fringe frequency in CGH, and tested a 100-mm diameter convex surface with full aperture by measuring it twice with proper pinholes.
