Overview of Universal Headgear
Universal headgear allows for the positioning of fibers on the whole head or just an area of interest. The signal from the sources located closer to the detector fibers probe the superficial layer; the signal detected from further distances from the detector bundle probe a more shallow region. Therefore, it is possible to separate the contribution to the signal from different layers by positioning sources and detectors judiciously. The headgear provides emitter-detector distances and a variety of montages for disparate applications.
Key Features of Universal Headgear
- Low profile, very flexible, comfortable
- A variety of emitter-detector positions available
- Inline detector/emitter geometry maximizes overlap of sample tissue
- Allows measurements on curved surfaces
Key Characteristics of Universal Headgear
- Pad is made of ethylene-vinyl acetate strips
- A total number of 9 strips held together by sagittal elastic strips
- 400 µm emitter fibers with 3 mm collector fiber detector bundles; 2.5 m long
