Probe design
First Claim
1. An optical probe, for acquiring measurements of material in a surface, the probe comprising:
- a probe body;
at least one illuminating optical fiber that transmits light to a distal end thereof to illuminate a region of the surface and interact with the material; and
at least one receiving optical fiber, positioned to receive light that has been transmitted by the illuminating fiber to the region and has interacted with the material, which received light is used for acquiring the measurements, the receiving fiber thereby being defined as associated with the illuminating fiber;
wherein at least one of the fibers has a portion inside the probe body with a bend.

28. An optical probe, for acquiring measurements of a material, the probe comprising:
-
a plurality of optical fibers adapted for transmitting light to and from the material to acquire said measurements; and
a light-blocking material, covering at least a portion but less than 50% of at least one of the optical fibers, that reduces optical crosstalk between the fibers. - View Dependent Claims (29, 30, 31, 32)

33. An optical probe system for measuring blood flow in a tissue region, the system comprising:
-
a first optical circuit that provides light that interacts with the tissue and generates a first signal indicative of the blood flow in the tissue region, responsive to the interacting light; and
a second optical circuit that generates a second signal that indicates when the first signal is affected by a motion artifact. - View Dependent Claims (34, 35, 36, 37, 38, 39, 40, 41)

42. An optical probe for acquiring measurements of material in a surface, the probe comprising:
-
a plurality of illuminating optical fibers that transmit light to illuminate spatially separated regions of the surface and to interact with the material in the regions;
a set of at least one receiving optical fiber associated with each of the illuminating optical fibers, each receiving fiber positioned to receive at least a portion of the light that has interacted with the material in the region illuminated by the associated illuminating fiber; and
an interface to a detector for each region, to convert light received from each region to a separate signal. - View Dependent Claims (43)
