Samsung Applies To Invent Retina Scanner Support

Rumour has it that Samsung intends to get involved in the production of support devices found in their Galaxy range of smartphones. In its newest bid to expand its creativity to different fields the company is embarking on a new field – iris scanning. It has been found that the human iris of the human eye possesses patterns that are akin to fingerprints.

Samsung patent Explanation

The process of iris scanning does not involve any contact whatsoever so those treated are spared the discomfort of other forms of eye treatment. Additionally, patients wearing eyeglasses or contact lens will not impede the scanning process that involves the identification of the patient’s iris. Because the scanning process takes a very brief two seconds it has been hailed as being more advanced than scanning of the retina.

As with other scanning treatments the scanning of the iris also requires a terminal for the storing of acquired information. The issue here is that with more sophisticated portable terminals such as mobile phones readily available, the need to store more information in the terminal rises and therefore security for terminals must also become sophisticated to handle the flow of information.

Nevertheless due to its accuracy, speed and absence of direct contact during treatment, iris scanning is vastly more efficient than fingerprinting or retina scanning. It follows therefore that a terminal for storing information must also undergo renovation to strengthen its storing capacity. This is vital since the stored data will subsequently be used for authentication purposes.

But as with every other invented product or service, iris scanning also has its own downsides. Firstly, the technique is not being applied to a terminal whether in Korea or anywhere else due to costs and problems related to the scanning rate. For non-Asians, iris scanning is a simple process that uses a standard flash to provide the lighting aspect.

For Asians, the process is more complicated as their eyes do not have enough melanin pigments meaning that infra-red rays won’t be able to illumine the non-existent pigment in the eyes of Asian patients. This lack of pigment necessitates the installation of an infra-red ray illuminator so that the scanning rate can be increased. But installing the infra-red illumination device will prevent the size of the terminal from becoming smaller.

Samsung’s solution to the issue is the invention of a device that will increase the rate for iris scanning. It has done so by embedding of a proximity sensor in the scanner instead of installing a separate infra-red illuminator within the terminal itself.  The company also intends to provide a special terminal with an illuminator for scanning that complements proximity sensing.

Detailed schematic descriptions of both the terminal composition layout and a flowchart depicting the procedural mode for the iris scanning and proximity sensing fully explain how the scanning is done. The terminal diagram clearly illustrates the operation mode, scanning mode and proximity sensing mode, also depicting input options for supply, lighting and a control element.

The iris scanning system is a highly sophisticated innovation into the scanning field covering miniature areas like the eyes. No doubt the science will further develop with time and become an even more unique and efficient method of scanning parts of the eyes.
