The main purpose of the IDM research of prof. Tengström was to confirm the possibility of determining instrumentally the refraction angle in the field even over long distances.

An appreciable increase of the accuracy could only be achieved by further improvement of the instrument. Even with the first laboratory model it seems possible to achieve an increase of the accuracy in the final results. This paper discusses the above possibilities and proposes some methods to achieve this improvement in the accuracy.
