Abstract

We exploit the terminal voltage sensitivity of self-coupled vertical cavity lasers to image a target with variable reflectivity. The technique does not use lock-in amplification, ensuring minimal components in the experimental setup. We demonstrate the imaging of a feature of the air force resolution target using this technique.
