1. A monitoring device that monitors deformation of a casing installed in a wellbore and housing a production tubing extending from a surface into the wellbore, the monitoring device comprising:
a packer that is installed within an annulus between the casing and the production tubing;
a deformable substrate that is disposed at an outer side of the annulus and contacts an inner surface of the casing to deform along with the deformation of the casing;
a light source that is disposed on the deformable substrate and emits light towards an inside of the annulus;
an imaging device that is disposed in the packer to be opposite to the light source across the annulus and detects the light emitted from the light source; and
a processor that produces a signal from the detected light, processes the produced signal, and transmits the processed signal to a surface control device that monitors the deformation of the casing based on the signal.
