every application, but rather each application will require separate consider-

2.11.1 Special Application Lighting and Laser Illumination
An interesting test application for lasers is producing sufficient illumination
to acquire high-speed video (frame rates up to a million frames per second)
and to image through high-luminosity events such as fireballs. Previous
laser illumination systems [84-87] required complex pulse timing, exten-
sive cooling, large-scale laser systems (frequency-doubled flash-pumped
Nd:YAG, Cu-vapor, Q-switched ruby), making them difficult to implement
for illumination in high-speed videography. Requirements to illuminate
through the self-luminosity of explosive events motivated the development
of high-brightness imaging techniques obviating the limitations of previous
attempts. Vertical cavity surface-emitting laser (VCSEL) arrays and a lens sys-
tem were utilized with temporal and spectral filtering to effectively remove
