Sentence examples for front error from inspiring English sources
Geometrical optics calculations obtained with Zemax® for each lens design are provided for the modulation transfer function (MTF), point spread function (PSF), encircled energy, transverse ray fan plots, root-mean-square wave front error (RMS WFE), chromatic focal shift, field curvature, distortion, and RMS WFE versus wavelength.
After adaptive optics correction the rms wave front error was reduced to 0.030 µm corresponding to a diffraction limited wave front.
The same pulse energy does not suffice to create a visible effect for conventionally minimized aberrations with λ/3 rms wave front error of the model eye (Fig. 8b).
The transmission of 120-fs laser pulses is given as a function of incident pulse energy for minimized aberrations with an rms wave front error of λ/3 (aberrated) and for aberrations corrected to the diffraction limit (corrected).
We found that for initial aberrations with a root-mean-square wave front error of only one third of the wavelength the threshold energy can still be reduced by a factor of three if the aberrations are corrected to the diffraction limit by adaptive optics.
The pulse energy with 50% probability for a scattering event was determined to be 1.1 µJ in the corrected case with diffraction limited wave front and 2.3 µJ in the aberrated case with λ/3 rms wave front error of the model eye.
The relationship curves show that some have different wave-front error RMS values when segmented mirrors have same position errors.
Under unparalyzed accommodation conditions and during a time-lapse of 2 seconds there are maximum RMS wave-front error variations of σ ∼0.02 μm with random characteristics [ 18], corresponding to a random Strehl ratio variations of Δ S=0.02.
Both of these sensitivities can lead to large residual wave-front errors when reconstructing large aberrations.
The owls in our study reported all stimuli as being located in the frontal hemisphere, and therefore committed back-front errors under all conditions.
The standard deviation of the wave front rms error is 6 nm for the flat mirror and 3 nm for the static deformed mirror.
