Wyle and its contractor teammates support the Lighting Environment Test Facility’s (LETF’s) at NASA Johnson Space Center. The role of this group is to investigate and evaluate proposed lighting systems for use on space vehicles to enhance the crews' direct and indirect viewing. This effort includes the investigation, measurement and analyses of:
- Artificial lighting systems such as docking lights, portable lights and navigation lights
- Reflective characteristics of various materials and the effects of solar lighting
- Transmission characteristics of transparent materials used for visors, displays and windows
- Camera performance for minimum and maximum illumination
In addition, LETF is active in the research and development of new and advanced technologies such as solid-state luminaires, photo-luminescence technology, radio-luminescence technology and the computer modeling of light. Working in conjunction with the Graphics Research and Analysis Facility, the LETF uses tools such as illuminance and luminance meters, colorimeters, gonio-reflectometers, special purpose luminaires, scale models and computer modeling to perform its analyses and predictions.
