FORUM C&C OGSE Laser Path: Speckle Angular Characterization

In 30 seconds

The FORUM mission utilizes a vacuum-based Optical Ground Support Equipment system to characterize far-infrared sensors at 9 μm and 11 μm. The system employs gas lasers injected into polycrystalline infrared fibers and a large-aperture integrating sphere to simulate mission-relevant radiation conditions. This setup addresses the critical need to characterize output radiance speckle to ensure instrument calibration accuracy.
