Why do we need VSEM?
Our research has led to a number of observations which lead to our perception of a requirement for software like VSEM:
- As SEM technology has developed, the user has become increasingly isolated from the inner workings of the instrument. The result is that users trained on modern machines are less able to use detailed knowledge of how the SEM functions to produce good images than the users of yesteryear. VSEM will put the necessary scientific knowledge at users' fingertips;
- In many laboratories, there is heavy demand on SEMs for available instrument time. This puts pressure on training schedules and reducing the time available for learning how to use the microscope. Likewise, skilled trainers are often at a premium, since they usually have other commitments aside from training. VSEM will allow new users to learn the basics at their desk, enabling them to make best use of their time on the real SEM and with experienced users;
- Universities and schools teaching students about the SEM may rely on theoretical material, with little or no access to real instruments. VSEM will help to fill the gap between theory and practice, enabling students to gain a better understanding of the relevant concepts.
These needs indicate that VSEM will be useful for:
- Experienced users in both industry and academia, for revision of their knowledge or checking how to carry out specific procedures;
- New users in industry, for familiarisation with the SEM and assessment of their competency to perform tasks;
- New users in academia, for familiarisation with the instrument, developing a good understanding of microscope theory and practice, and for assessing their competency with and knowledge of the equipment.
Not surprisingly, there has also been significant interest in the project from museums who are interested in using the technology as an interactive exhibit. The simulator in particular is seen as a valuable tool, both for gaining an understanding of what it is like to use a SEM and also for examining sample SEM images.
