The 3D coordinates of measured point is embodied in 2D image coordinate of the optical characteristic point via the visual measurement system. Based on the gray square weighted centroid localization algorithm
the paper presents bicubic interpolation gray square weighted centroid localization algorithm
increases the number of effective pixels around the optical characteristic point imaging center
and reduces noise error via the gray square weighted
improves the imaging center location accuracy of optical characteristic point
realizes the accurate location of the optical characteristic points. Results indicate application of the proposed algorithm to location
the standard tolerance along the direction of x is 0.0022 Pixel
the standard tolerance along the direction of y is 0.0023 Pixel
compared with the others
the standard tolerance is minimum and discrete to a lesser degree distancing ideal image point
that is
the proposed algorithm has higher location accuracy. The maximum tolerance along the direction of x is 0.008 Pixel
the one along the direction of y is 0.007 Pixel
compared with the other two algorithms
the maximum tolerance is minimum.Results indicate that the stability of the proposed algorithm is better. (2013) Trans Tech Publications

High accuracy is required in surface testing of 90nm nodal point lithography projecting lens. By comparing various aspheric surface testing methods
the structure layout of the compensator is a meniscus positive lens combined with a Plano-convex positive lens. The design results indicate that: primary and high order aberrations are balanced well
we adopt Offner null compensator to test the aspheric surface in the point diffraction interferometer at last. In this paper
MTF exceeds diffraction limit
an Offner compensator is presented on the base of the third order aberration theory to test concave aspheric surface
root-mean-square (RMS) of wave front error /167. The F-number of the system can achieve F/1.64. By the analysis of the process of aspheric surface testing with the designed system
the optical construction parameters of which is determined by introducing equal-quantities spherical aberration to compensate all orders of aspheric coefficients. The field of view of the system is 0.02
a loosen distribution of the tolerance was presented based on the accuracy of measuring apparatus. 2009 SPIE.

In this paper
a color gamut transformation method which transformed the different color gamut into a same one has been proposed. In the transforming process
the deviation which was arose from the quantization error and the truncation error were existing. If the deviation was out of the color tolerance
the uniformity of the screen color will be deteriorated. Firstly
the color tolerance of vision was calculated by the color-difference formula. Secondly
in the full-color LED display experiments
it was analyzed that the tri -color tolerance values are respectively 2.5
2.8 and 1.3. According to the tri -color tolerance values and the color difference formula
the express of the quantization precision
gray value and the color difference was set up. Finally the gray-scale range of the color uniformity was analyzed by the collected data
it was concluded that the uniformity of the display was satisfied the requirement of the visual when the range of the gray level was [11
14]
and when the range was [1
11]
the value of the color difference was also reduced significantly. 2009 IEEE.

The wavefront coding technology is known as a system-level technology which can extend the depth of focus of optical system by innovative optical design and image restoration. This technology can control misfocus related aberrations including misfocus
astigmatism
and Petzval curvature
temperature-related misfocus in digital imaging systems. It can also help optical system tolerate more residual error in optical manufacturing and alignment besides misfocus. The brief introduction of wavefront coding technology and the wavefront coded TMA system under research is presented respectively in part 1 and part 2. The "MTF similarity" is defined to describe the relationship among MTF at different position or different fields in the third part. It is also shown in this part that the MTF similarity of wavefront coded system is much higher than the normal system within a large range. In part 4 comparison between the origin system and the new system with wavefront coding technology is provided after multiple errors are introduced
from which it can be observed that the system with wavefront coding technology can tolerate much bigger error than origin system. The error tolerance is re-distributed according to a new criterion based on MTF similarity. If the MTF similarity is less than a certain value
it can be regarded that the system can tolerate the residual error. The new error tolerance is displayed and it is shown that the wavefront coding technology can also loosen the error distributing besides extended the depth of focus.
