Tel Aviv University’s (TAU) Ramot Momentum Fund has unveiled this week its breakthrough ‘Unispectral’ SmartCam Technology at the MWC15 Barcelona Mobile World Congress. Unispectral by Ramot at TAU Unispectral is being funded by the Technology Innovation Momentum Fund of TAU’s Ramot tech transfer arm, whose lead investors are India’s Tata Group and Singapore’s Temasek Holdings. Another key investor is the SanDisk Corporation, with the balance of the investments provided by angel investors, primarily from South Africa, US and India. Shlomo Nimrodi, CEO of Momentum Fund and Ramot, commented: “The Momentum Fund represents an innovative approach for early stage innovations utilizing a for-profit investment mechanism with the support of strategic partners.”

Unispectral‘s Superior Imaging Technology

TAU’s Unispectral technology aims to break the image quality bottleneck by replacing the Bayer color filter array with a tunable spectral filter and complementary image fusion IP-core. The technology, backed by multiple patents, is compatible with compact camera modules and common computational platforms. The solution includes a reference design of the optical component and SW library.

Hyperspectral sensors look at objects using a vast portion of the electromagnetic spectrum, enabling a wide range of applications such as astronomy, agriculture, biomedical imaging, mineralogy, physics, and surveillance, as well as smartphone cameras, wearables, and IoT. Unispectral cameras include an additional optical component that replaces the Bayer color filter array and IP-core, suitable for heterogeneous computational platforms. The solution is integrated with common hardware, such as rolling shutter image sensors and a plastic injected lens. The component was designed for compact camera modules with small form-factor, low power consumption and high frame rate support.

Unispectral‘s Benefits

Much as the human eye sees visible light in three bands (red, green, and blue), spectral imaging divides the spectrum into many more bands. This technique of dividing images into bands can be extended beyond the visible. Unispectral cameras offer 2x more light captured, 2x resolution and improved dynamic range compared to standard compact cameras. Thus, Unispectral cameras achieve image quality improvement by utilizing common components. Furthermore, each camera is transformed into a smart camera, enabling multiple M-health applications that used to require stand alone spectroscopes.

Hyperspectral Imaging Technology

The Momentum Fund’s hyperspectral imaging technology (HSM) enables fast and reliable scanning of wavelengths for various sensing, detection and imaging applications. It aims to improve image quality and to equip any standard camera with hyperspectral imaging capabilities. It is a highly accurate, MEMS based, tunable spectral filter with closed loop feedback mechanism. HSM is especially suited for mobile cameras as well as other cameras, spectrometers, medical and industrial cameras, etc. Some of its unique advantages include small form factor, adding hyperspectral functionality to all camera types, wide wavelength range (UV, VIS, NIR, IR), flexible transmission spectra, power efficiency, and low cost. hyperspectral imaging tech
