Using Active Vibration Control Systems to Stabilize DIC Microscopy Systems

Differential interference contrast (DIC) microscopy is a specialized technique used in the study of live and unstained animal and human tissue samples in medical science. The accuracy of the system relies on the spatial uniformity of its many parts. Due to this, active vibration control is necessary to ensure image accuracy. 

DIC microscopy is a method of optical microscopy illumination that enhances contrast in transparent specimens. Polarized light is directed into a modified Wollaston prism to split the light into two separate beams. One of the beams is directed towards the specimen, while the other only passes through the background. Both beams are recombined through another Wollaston prism, located above the microscope's objective lens.

This technique is able to produce contrast that visually displays the gradient of optical paths in every part of the specimen. The resulting image is monochromatic and has a three-dimensional appearance. 

The components of a DIC microscopy system, including the light source, stage, and prisms, must maintain uniform distance to ensure the clarity of the image. Subtle vibrations coming from the central HVAC unit, equipment in adjacent rooms, and traffic along the hallway can affect the system and decrease the quality of results. Noise from outside the building and the equipment present in the lab also produce vibrations.

Active vibration cancellation systems are necessary to ensure the stability of DIC microscopy systems. These advanced systems utilize piezoelectric sensors and actuators to detect incoming vibrations and react by either tuning isolators to minimize vibrations or sending a signal to cancel them out. The system also creates a feedback loop that dampens inherent resonances in mechanical structures. Active systems can be combined with passive isolation systems, such as stiff metal springs for load support, to isolate a broad range of frequencies.

Guest Post: Microsoft Launches the All New Windows 8

The final and fully finished version of the much talked about operating system Windows 8 is out now. On Friday, Microsoft also surfaced Windows 8 based devices in the retail markets. Though there have been several add-on and up gradations in this new version of Windows, but you need not like all these additions. There are, however, certain features in the new OS by ASP.Net application development giant that ought to be celebrated.

2. File History: Very similar to the Time Machine utility of OS X, this feature of Windows 8 lets save multiple copies of your file. So, in case the current version of your file is lost, the other versions can be easily restored.
3. Charms Bar: If you have used Windows 8 as of now, you will be aware of the newly added Charms bar feature. It appears on the right hand side of the screen, if you swipe or click there. This feature is much more effective and resourceful than it seemed to be in the earlier versions of the OS. The charms bar icon provides the user with several icons for tasks such as sharing, searching, switching between Windows 7 desktop and metro environment and setting preferences.
4. Live Syncing: The live syncing feature is very resourceful. It lets you log into your Windows Live account just as you log onto your PC. Moreover, your Windows Live personalized settings can be traced down on any device that you use, provided you are using the same Live account.
5. Windows Reader: This is a built-in app in Windows 8 that lets you open a PDF file and take notes or highlight specific areas in it. Furthermore, you can also import PDFs in Word 2013 and edit them in their text form.
6. New and Improved Task Manager: This is one feature of the new OS that webmasters and admins would love in person. The revamped task manager gives a more specific and detailed view of the processes that are currently running.
7. Microsoft Store: Just like you get apps on your Windows phone, you can get Metro apps for your PC from the Microsoft Store. It is easy and quick.
8. Windows to Go: You can have the Enterprise Edition of Windows 8 with you on the go. Users can easily download the Windows environment on an external drive and then it can be used on any device that is compatible with Windows 7 and Windows 8.

The thought of a new operating system is overwhelming for any web application development company. If you are also super excited about the release of this new operating system, try it today!
