Compared to the limited measuring range of traditional white light interferometry, the maximum distance can be extended to arbitrary length.

相对于传统白光色散干涉技术的有限测量范围，最大测量距离可以扩展到任意长度。

This is done using a technique called interferometry, which merges the beams of light in a way that simulates the sharpness (though not the brightness) of the images that would be obtained from a telescope whose mirror was 200 metres across.

To measure the refractive indices of different parts of a cell they use a technique called interferometry, which involves splitting a beam of light in two.
