Making advanced biometrics mobile for a wide consumer audience
Personal monitoring for health, fitness and personal security has long been limited by the lack of sensors capable of providing meaningful biometric information in the mobile environment. Compact Imaging is changing that with MRO (Multiple Reference Optical Coherence Tomography), an advanced miniature optical imaging and analysis technology that will enable mobile devices to non-invasively gather biometric data from inside the body.
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 consumers.
With its miniature, low-cost, battery-powered MRO sensor technology, Compact Imaging is revolutionizing the way personal biometric monitoring devices can be marketed and sold. MRO is a non-invasive sub-surface scanning technology suitable for integration with smartphones, tablets and wearables. It will place precision biometric and imaging capabilities at the disposal of mobile device designers and application developers to address security, health, fitness and other mobile monitoring applications. MRO will provide people vital, advanced biometric information when and where they need it most.
Compact Imaging’s MRO (Multiple Reference OCT) technology is a new form of time-domain optical coherence tomography (OCT). OCT, which has been widely adopted in clinical settings, is similar to ultrasound but, instead of sound, uses light to scan 1 – 2 mm below the surface of tissue or any translucent material and detect its light scattering properties. MRO makes available the safe and powerful scanning capabilities of conventional OCT but will simplify and miniaturize them for use in mobile applications. At the core of the MRO architecture is a reference mirror mounted on a low-cost actuator, such as a voice coil. When paired with a partial mirror, the combination enables MRO to generate multiple reference signals simultaneously that interfere with light back-scattered from various depths within the target. These result in continuous depth scans that can be processed into images and measurements of the target’s features, properties and behaviors.
