1. A core holder for core testing, the core holder comprising:
a body having a cavity defined therein;
a sleeve disposed within the cavity;
a chamber defined within the sleeve, the chamber to hold at least one core plug; and
at least one fiber-optic sensor disposed at a perimeter of the chamber, the at least one fiber-optic sensor to sense at least one parameter related to flow of fluid through the chamber,
wherein the at least one fiber-optic sensor comprises an optical fiber having a sensing region extending along an axial direction of the core holder, and wherein the optical fiber is attached to or embedded in an inner surface of the sleeve,
wherein the at least one fiber-optic sensor is a fiber-optic temperature sensor, a fiber-optic pressure sensor, or a fiber-optic pressure and temperature sensor, and
wherein at least a portion of a wall of the body is made of a transparent material to allow visual monitoring of a condition within the cavity.
