It is very familiar to use the transmission type double slit interferometer to measure the incident light wavelength, theoretically, it is feasible to use the transmission type double slit interferometer to measure the tiny displacement, and the measurement precision is very high, actually, because there is a light blocking strip between the transmission type double slits, the width of the light blocking strip must be smaller to make the distance between the double slits very small, the measuring of the tiny displacement by the double slit interference effect is the variation of the width of the light blocking strip, however, it is very difficult to narrow or widen the width of the light blocking strip between the transmission type double slits which are very small in width, which is the reason that the transmission type double slit interferometer is used to measure the object tiny displacement directly.
When the interference image is adjusted, the optical path difference of the two beams of amplitude-splitting light is ensured to be small and to be overlapped in parallel, otherwise, the interference image cannot be seen, and a plurality of beginners usually waste a lot of time in the process, and some of the beginners even cannot adjust the interference image at all. The images of the movable reflecting mirror surface and the fixed reflecting mirror surface near the former are not parallel, so that the image involved is not easy to adjust as soon as possible, and the fact that the optical paths of the two beams are adjusted to be basically equal in advance is not easy to grasp by many beginners.
