Spot Mode Video

Enabling rapid identification and resolution of vibration, magnetic field, and acoustic noise disturbances on electron microscope images

What is Spot Mode Video?

VEC uses its innovative Spot Mode Video technique to identify and resolve sources of disturbance on electron microscope images.  Service engineers often conduct initial measurements for vibration, magnetic fields, and acoustic noise levels.  However, specific sources degrading microscope performance often remain unclear. Spot Mode Video enables VEC engineers to correlate disturbances on the image to specific sources in the environment.  Using this technique, VEC effectively prioritizes remediation to provide the greatest return for clients.

How does Spot Mode Video identify vibration, magnetic field, and acoustic noise disturbances on electron microscope images?

Sources of vibration, acoustic noise, and magnetic field generate unique disturbances on an electron microscope image.  For instance, a pump vibrating at 29.4 Hz creates a 29.4 Hz disturbance on the image.  Similarly, an AC magnetic field emitted from a conduit with improper wiring causes a 60 Hz disturbance.  Using our Spot Mode Video technique, a VEC engineer extracts the specific frequencies impacting image quality.  VEC uses this data to pinpoint these sources in laboratories and addresses them directly.

Advantages of Spot Mode Video

Using Spot Mode Video, VEC engineers determine which environmental sources are disturbing the image, and which are not. In addition, it provides a quantitative assessment of the relative impact of each vibration, magnetic field, and acoustic noise source. VEC uses this information to effectively advise clients on investment priorities.  Therefore, clients can focus their resources on solutions that optimize performance while avoiding unnecessary expenditures.
