Retinal Scans As Seen Most Famously Done By James Bond

Retinal scans, as seen most famously done by James Bond, are a means of identification that is collected by casting a beam of low-energy infrared light into the eye while the eye looks through a special eyepiece. What is a retinal scan? A retinal scan is a map of the blood vessels within the retina, which is unique to each person. A retina is the part of the eye responsible for vision. The process in which retinal scans are produced relies on generating many images of the retina using a low intensity infrared light. Eye prints, also known as retinal scans, can be used as a form of identification because of the validity, many advantages, and few disadvantages.

Initially, retinal scanning is the least used form of biometrics, but it is in fact a valid form of identity. For example, a retinal scan takes many images of the unique capillary pattern in a person’s eye, so it is hard to fake. In fact, since the retina capillary pattern is a physiological pattern it does not change over the course of one’s life. This is relevant because, unlike a fingerprint, it cannot be changed or attempted to change as it is an internal organ and as such is less susceptible to modification. Also, genetic factors do not determine the pattern of the blood vessels, so it can be used to differentiate between twins.

Retinal scanning systems are highly accurate. For example, many are used on government or military protected buildings because of the high accuracy. Another amazing advantage is the fact that they are nearly impossible to spoof; since it is an internal organ it cannot be replicated outside of one’s own body. Also, it can be used to diagnose diseases, both hereditary an non. Examples of the diseases not hereditary include: AIDS, malaria, Lyme Disease, chicken pox. As for hereditary a retinal scan can detect lymphoma, sickle cell anemia, and
