Digital holographic microscopy for silicon microsystems metrology

Christian Depeursinge, Yves Delacrétaz

We propose to use digital holographic microscopy (DHM) with an illumination in the near infrared spectrum bandwidth, where the silicon is known to have small absorption. With such an illumination condition, it is possible to observe a wider range of specim ...
