Book Description

This Spotlight, intended for those learning how to perform laser-damage measurements on cameras, explains the importance of a camera's laser-induced damage threshold (LIDT) and how it can define protection measures. The book walks through the experimental methodology and testing considerations to measure the damage threshold of an off-the-shelf visible-band CCD camera to a pulsed laser under laboratory conditions. This same methodology can be applied to other 2D detector arrays, and the steps to adjust the experimental process to perform continuous-wave LIDT measurements are described. Finally, data-analysis techniques relevant with this type of experiment are discussed.

Preface

This Spotlight is intended for experimentalists learning how to perform laser damage measurements on cameras. The importance of understanding the laser-induced damage threshold of a camera and how it can define protection measures is discussed. A guide to the experimental methodology and testing considerations to measure the damage threshold of an off-the-shelf visible-band charge-coupled device (CCD) camera to a pulsed laser under laboratory conditions is presented. This same methodology can be applied to other 2-D detector arrays, and the steps to adjust the experimental process to perform continuous-wave laser damage threshold measurements are described. Finally, data analysis techniques relevant to this type of experiment are addressed.
