Abstract
We have investigated the speckle contrast using different configurations: we place the screen either in the imaged near-field or in the far-field of the VCSEL´s emission whereas the CCD is placed in the near-or the far-field of the screen. The measured speckle contrast is strongly dependent on both the configuration and the driving conditions of the VCSEL.
