Remote monitoring for identity authentication and health status has long been limited by the lack of devices capable of sensing meaningful information from below the surface of the skin in non-clinical or remote settings. Compact Imaging changes that with its MRO (Multiple Reference Optical Coherence Tomography) technology, an advanced miniature optical imaging and analysis system that enables non-invasive collection of biometric data from inside the body but outside a clinic or lab environment.
Sophisticated instruments for directly imaging and measuring the features, properties and behaviors of human tissue already have been widely adopted for use in medical clinics. These devices, however, are either invasive, emit harmful radiation or are simply too big, expensive and power hungry to provide immediate and meaningful data to mobile users or remote sites.
With its miniature, low-cost, low power MRO sensor technology, Compact Imaging is revolutionizing the way biometric monitoring devices can be developed, marketed and sold. MRO is a non-invasive subsurface scanning technology suitable for integration with a range of mobile and remote-use devices. It places precision tissue imaging and measurement capabilities at the disposal of device designers and application developers to address security, health and other mobile monitoring applications. MRO will provide people, enterprises and civil authorities vital, advanced biometric information when and where they need it most. Talk to us about your application.
MRO measurement of central macular thickness (CMT), for example, addresses the growing need for an affordable home monitor that can acquire and wirelessly transmit clinically useful information about the progression of conditions of the eye that manifest with macular edema (ME), such as age-related macular degeneration (AMD). Conventional clinic-scale OCT (Optical Coherence Tomography) machines, operated by highly trained clinical staff, are large, expensive and complex. Although they are indispensable clinical diagnostic tools, these machines are completely unsuited for home monitoring of disease progression post-diagnosis and treatment. Consequently, routine monitoring is performed in clinical settings. This imposes a substantial burden of care on patients and overloads clinics with costly examinations even when no treatment is indicated.
Biometrics, such as fingerprints, have been around for decades, but in recent years the need for greater security of biometrics has increased dramatically. Even with the latest improvements, conventional fingerprint scanners only provide a 2D or, in a few cases, a 3D image of the visible human fingerprint, making them susceptible to presentation attacks and false positives as well as time-consuming delays in authentication.
MRO leapfrogs these technologies by scanning below the skin surface to provide an image of the primary, or sub-dermal, fingerprint in addition to the conventional surface fingerprint. Since MRO detects fake layers that may have been applied to the surface fingerprint and since the sub-dermal fingerprint cannot be confounded by non-existent or physically altered surface features, it cannot be “spoofed” by any known means. Moreover, MRO depth images reveal blood flow and other dynamic features of living tissue to prove “liveness.” Is it real? Is it alive? Is it authentic? With MRO, you’ll know.
From the farm to the manufacturing floor, destructive testing for production quality assessment and control has been an accepted cost of doing business. MRO’s subsurface scanning capabilities create a small, low cost means to leave behind these expensive and time-consuming methods. With MRO technology, you’ll be able to develop and market non-destructive mobile sensors to detect everything from the cure rate of adhesives and the integrity of packaging seals to the fertility of seeds, all without puncturing a layer, opening a package or destroying an embryo.
Eric A. Swanson, one of the pioneers in the development of commercial OCT, recently spoke about the past, present and future of this powerful subsurface imaging technology, including in a number of emerging applications in which small, low-cost OCT systems—such as Compact Imaging’s MRO, or Multiple Reference OCT—will play a significant role. The entire talk is worth watching, but click the video on the left to see the part of the presentation where Swanson mentions the use of Compact Imaging’s technology in biometric security.
