| 1. A method for winding a crossover-free fiber optic coil sensor comprising:
a) winding fiber optic cable onto a first supply spool and a second supply spool;
b) attaching the fiber optic cable to an outer edge of a coil form, wherein the coil form comprises a first side and a second
side;
c) forming a first outside-in coil layer on the first side of the coil form using a first winding head, wherein the first
supply spool supplies fiber optic cable to the first winding head;
d) attaching a first inside-out separator to the first outside-in coil layer;
e) forming a first inside-out coil layer on the first inside-out separator using the first winding head;
f) forming a second outside-in coil layer on the second side of the coil form using a second winding head, wherein the second
supply spool supplies fiber optic cable to the second winding head;
g) attaching a second inside-out separator to the second outside-in coil layer; and
h) forming a second inside-out coil layer on the second inside-out separator using the second winding head.
