Sensors

Adult Flexible Sensor   

The flexible sensor is made from polyurethane rubber in which fiber optics and prisms are embedded. It has been designed for measurements on curved surfaces such as the head. Right hand and left hand versions are available for simultaneous dual head monitoring. The body is larger than the equivalent neonatal head scanner and is thus less susceptible to stray light and background light complications. The sensor may be held in place by medical adhesive that is attached to its surface.

Key Features
  • Low Profile, Very flexible and Comfortable
  • Many choices concerning emitter distances and number of emitter positions
  • Side entry fibers allow for maximum flexibility of the sensor
  • Inline detector/emitter geometry maximizes overlap of sample tissue
  • Allows measurements on curved surfaces
Key Characteristics
  • Flexible rubber molded construction
  • Four emitter positions with eight emitters
  • Standard fiber length 2.5 m (up to 10 m fibers available)
  • Standard emitter-detector distance; 2.0, 2.5, 3.0, 3.5 cm
  • Custom emitter detector distances available:
    1.5, 2.0, 2.5, 3.0 cm
    2.5, 3.0, 3.5, 4.0 cm

Dual Flexible Sensor   

The dual sensor optical probe, utilized for measurements on the forehead, has been developed for measurements that require the simultaneous data acquisition on both frontal lobes of the brain (for instance, sleep apnea, ADHD). The sensor is made of soft and flexible polyurethane and accounts for forehead curvature effects, as well as sampling through the skull into the brain (effective source-detector separation range). The sensor may be attached on the forehead by means of a medical adhesive in a symmetrical configuration, so each sensor acquires data simultaneously, from the right and the left frontal lobes of the brain respectively.

Animal Sensor   

The animal sensor is for research on small animals (rats, rabbits, pigs, etc.). The sensor consists of a black plastic baseplate, eight 400 μm-diameter core emitter fibers and a collecting 3 mm-diameter fiber bundle. The fiber tips are inserted through the holes in the plastic baseplate; the protruding fiber tips length is easily adjusted to fit the shape of the sample. A rubber gasket holds the fibers in place and provides a spring-like tension to the fibers. The emitter fibers are filtered to balance optical intensity at the detector for a specific range of emitter-detector distances. To block the direct reflection of the light, a replaceable, black, foam rubber strip is placed on the bottom of the sensor between the detector input and emitter output tips.

Helmet   

The detector helmet 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 deeper region. Therefore it is possible to separate the contribution of the different layers to the signal. The helmet provides several emitter-detector locations. More emitter-detector pairs allow for better localization of the area.
