Sentence examples for optical errors from inspiring English sources
The effect of optical errors was also considered in the simulations.
And the effects of the solar brightness distribution and optical errors (e.g., alignment error and tracking error) are also involved.
In most situations, it is the characteristics of the observer that are the primary sources of blur – i.e. their optical errors.
In contrast to the classical optical errors, the wavefront aberrations of higher order can not be corrected by means of glasses or contact lenses.
A theoretical study is carried out to understand the effect of the size of facets and of their optical errors in multiple facet point focus solar concentrating systems.
For this purpose, a ray tracing program was developed based on the convolution technique, in which the brightness distribution of the sun and the optical errors of the reflecting surfaces are considered.
Instead of treating all optical error sources as probability distributions and convolving them with the sun shape into an overall beam spread function, FirstOPTIC treats mirror slope error, receiver position error, and collector tracking error as geometric modifications to the collector, as interpreted in laboratory measurements.
Comparison of the flux density distributions between this method and SolTrace show excellent agreement especially when the optical error is equivalent to or larger than the Gaussian function parameter of heliostat image which fits to most of heliostats in a solar tower system.
After training, however, his objective refraction (retinoscopy) showed a small myopic optical error, and therefore the best optical correction (−0.5 diopter in each eye) that met the objective prescription was prescribed.
The RMS optical error was not statistically different between both eyes in any of the conditions (p > 0.1). Figure 3 shows the binocular VA under the 3 conditions for all the 5 subjects.
The numerical results indicate that the reconstructed source centers are off their actual locations to the phantom edge, and the reconstructed source powers are lower than the actual values in the positive optical error cases.
