Include Vector Data: If your image contains any vector objects or type for which outline data is available (not outline or protected fonts), select this check box to send the actual vector data to a PostScript printer. Your vector objects then can be scaled to any size without degrading in quality. Including the vector data increases the image file size, which can slow printing and cause other printing problems. But if you turn off the check box, everything in the image is sent to the printer as raster data. This reduces the file size, but you no longer can scale the vector objects or type with impunity. They re subject to the same quality loss that occurs when you enlarge any pixel-based image.

plane, the marginal rays will arrive at the observation plane at the same point where the corresponding ray following the path through the reference mirror arrives, as when there is no aspherical deformation, even if the path followed by the ray is different By Fermat s principle, the optical path from any point on the surface under test to the observation plane is the same for all possible paths, automatically correcting the error In conclusion, when there is no proper imaging of the surface being tested over the detector, there will be an additional aberration added to the nal interferogram However, in this case, when the entire system is ray traced, the hologram can be designed to correct these extra aberrations if a null test is performed.

Another important consideration is that the test element may deviate the rays so much that the light re ected from the test surface will not get back through the interferometer In this case, a partial null lens must be used to ensure that light will get back through the system This is discussed in more detail in the section on the combination of CGHs with null optics Once the fringes are calculated, they are either plotted directly on a holographic substrate, or plotted and photographically reduced onto a holographic substrate The techniques of plotting have been substantially improved over the years Early work utilized pen plotters to make an enlarged version of the hologram that was then photographically reduced to the appropriate size (MacGovern and Wyant, 1971; Wyant and Bennett, 1972; Wyant and O Neill, 1974) The large format enabled a high-resolution CGH to be formed.

However, problems due to plotter irregularities such as line thickness, pen quality, plotter distortion, and quantization caused errors in the reconstructed wavefront Nonlinearities inherent in the photographic process and distortion in the reduction optics caused further degradation With the advent of laser-beam recorders, resolution improved due to machine speed and an increased number of distortion-free recording points (Wyant et al, 1974) The most recent advances in the recording of CGHs have been made using the electron beam (e-beam) recorders used for producing masks in the semiconductor industry (Emmel and Leung, 1979; Leung et al, 1980; Arnold, 1989) These machines write onto photoresist deposited on an optical quality glass plate and currently produce the highest quality.

Write a PHP function that accepts a four-digit year and a month number (1 12), and returns the number of weekdays (Monday Friday) in the given month. Use this function to calculate the number of weekdays in March 1997 and display the result. Modify the contact.php contact form script in this chapter to allow a visitor to send an email to anyone, not just the site owner. Include additional functionality to allow the visitor to copy the email to an optional carbon copy (CC) recipient. (Incidentally, such a script is easily exploitable by spammers, and therefore shouldn t be placed on a publicly accessible Web site.)

The results are very encouraging but more development is needed before it becomes a routine tool; this is an important research need 762 Modelling turbulence-chemistry interaction In a combusting flow, variables such as density and temperature are highly nonlinear functions of the chemical state We cannot simply calculate the mean value of the.

Creating an Ethernet LAN begins with installing of Ethernet adapters in or (in the case of USB adapters) on the PCs you wish to connect to the LAN via Ethernet. If you recently purchased a PC, you ll probably find a network card already in place. Examine the back of the case (or the back or side of the notebook PC) for an Ethernet port it looks a lot like a phone jack, except that it s a bit wider. If the connector on the Ethernet cable fits into it, then you have the adapter.
