Unispectral technology is comprised of three core building blocks:
- Optical Fabry-Perot tunable wavelength filter implemented as a micro electromechanical system (MEMS) element, suitable for mass production and compliant with the compact camera ecosystem
- Electronics that actuate the MEMS
- Image processing software algorithms that control the MEMS, fuse captured images and process hyperspectral information
Together with common image sensors, Unispectral technology is embedded within a compact camera.
Seeing More Than the Visual Spectrum
Unispectral technology unlocks sensor-seeing capabilities which are currently deliberately limited by other optical elements within the camera, enabling the device to capture a wider wavelength of visible and beyond visible shades.
There are a wide range of applications that could benefit from combining a selected NIR spectral band and visual spectrum within a single camera, and Unispectral enables this combination without compromising image quality.
Revolutionizing Digital Camera Technology
Today’s cameras use 40-year old Bayer filter technology, which trades off color (RGB) sensing with image resolution. In contrast, Unispectral’s filter is completely tunable, and takes full images in any tone. Multiple images in various tones can then be fused together with underlying software into a single unified image, leading to richer, higher quality images.
The Unispectral solution replaces current digital camera technology with a more cost effective alternative that offers superior quality photographs, especially in difficult conditions, enhancing cameras’ dynamic range.
Rather than the static green, red and blue filters of traditional digital cameras, Unispectral’s tunable filter can tweak the colors to compensate for different light conditions or accuracy and quality. For example, it can compensate for photographs taken at noon, or in low light. When these color enhancements are done optically, the results are higher quality, with truer colors, than when done in the image processing stage on a computer or another processing device.
To enhance images in low light conditions, Unispectral can add black-and-white exposure that enables the camera to collect more light; when the multiple images are fused together, the camera gains improved light sensitivity. This can greatly enhance photographs taken in the dark, or when shooting into the light.
2-in-1: Images & Near IR in One Filter
Leveraging its near infrared (NIR) capability, Unispectral eliminates the need to embed a costly, dedicated near IR sensor, instead providing NIR together with its regular RGB sensor. This combination of two sensors into a single sensor increases efficiency and reduces technological footprint. Combining RGB and NIR imaging on a single optical axis reduces the overall cost and complexity of the device.
Unispectral technology allows color cameras to support active illumination (e.g., LEDs) for applications including iris recognition, 3D mapping, hand gestures and facial recognition.
Unispectral is driving a revolution in sensing technology, bringing spectrometry to the masses by enabling smartphones and other devices with embedded cameras to determine the building blocks or ingredients of whatever is being photographed.
The same capability that at one time was available only to high end laboratories, research institutes and industrial facilities due to its high cost and complexity, can now be delivered to the public at large. A single sensor can handle both visual images (RGB) and hyperspectrometry, reducing complexity and overall cost.
The Unispectral technology and know-how can be licensed to manufacturers for use in all types of consumer-facing offerings, from smartphones to cars to refrigerators. The technology is mass-production ready.
