based on the scattering of optical elds from permitivitty gratings induced by acoustic waves. Even though acoustic frequencies are much less than optical frequencies, acoustic wavelengths may be small because the acoustic velocity in crystals is about ve orders of magnitude less than the speed of light. Unfortunately, maximum acoustic frequencies range from 100 MHz to 1 GHz, about six orders of magnitude less than optical frequencies. This means that the period of an acoustic grating is at least an order of magnitude greater than the optical wavelength. With reference to Eqn. (9.7) or to our plot of spectral selectivity versus Bragg angle in Fig. 9.17(a), we see that long-period acoustic gratings are unlikely to be effective spectral lters. The solution to this problem is illustrated in Fig. 9.32, which is a wave matching diagram for scattering from the ordinary polarization to the extraordinary polarization in a birefringent crystal. The wave normal surfaces are scaled to the indices of tellurium dioxide (TeO2), which is commonly used for visible and near IR lters. An acoustic wave scattering light from one polarization to the other must satisfy ka ke 2 ko, where ka is the acoustic wavevector and ke and ko are the wavevectors of the extraordinary and ordinary optical waves. Assuming collinear beams, the acoustic frequency is (ne no )v l

Sometimes, an original is so large that working with multiple scans is not practical. In a case like this, think about using a digital camera on a tripod to photograph the artwork instead of scanning it.

Link business intelligence tools to enterprise goals. Although the Level 2 organization may have been using business intelligence tools, they were tuned to departmental needs. The Level 3 organization stands to gain real value from business intelligence, because these tools can be applied to enterprise-wide data. Develop enterprise-level metrics and incentives to gauge progress, validate results, and overcome the us versus them mentality that pervades Level 2 organizations. Establish a climate where everyone has a vested interest in integration. Foster high levels of communication both from upper-level management and among department managers and their teams to alleviate the anxiety and mistrust that can accompany major change. Establish a council or center of excellence that will work to implement and sustain this integrated information environment. This group can address issues that arise even after integration is complete, thereby promoting the acceptance of success of this transition. Create practices that perpetuate the integration you have achieved. It is common for an integrated Level 3 company to fragment later as a result of reorganizations, mergers, and acquisitions. Be prepared for this possibility by having practices in place to apply the above steps whenever the organization goes through flux. At this new level, the information architecture integrates data from every corner of the enterprise from operational/transactional systems, multiple databases in different formats, and from all contact channels. The key is the ability to have multiple applications share common metadata the information about how data elements are derived and managed. With consistent metadata, applications that formerly would not talk to each other now contribute to shared, enterprisewide intelligence. The result is a collaborative domain that links previously isolated specialists in statistics, finance, marketing, and logistics and gives the whole user community access to company-standard analytical routines, cleansed data, and user-appropriate presentation interfaces.

Okay, you know that any zoom lens you buy is going to be 1 or 2 f-stops slower than a high-speed, fixed focal length lens. This may not matter much when you re shooting in bright sunlight or using a flash, but it can be critical when shooting in available light. To minimize camera shake in low light, thereby increasing the sharpness of your picture, shoot at the lowest possible f-stop and at the zoom lens s widest angle. If there s still not enough light to achieve correct exposure or eliminate camera shake, try upping the ISO equivalency. (See 5.) True, the image will tend to be noisy, but you will have gotten the shot.
