CurvACE Artificial Compound Insect Eye
CurvACE, a research group from EPFL in Switzerland, has announced a new artificial compound insect eye. The device could be used for small UAVs or other robots.
( CurvACE artificial compound insect eye)
In most animal species, vision is mediated by compound eyes, which offer lower resolution than vertebrate single-lens eyes, but significantly larger fields of view with negligible distortion and spherical aberration, as well as high temporal resolution in a tiny package.Compound eyes are ideally suited for fast panoramic motion perception. Engineering a miniature artificial compound eye is challenging because it requires accurate alignment of photoreceptive and optical components on a curved surface.
In CURVACE, we describe a unique design method for biomimetic compound eyes featuring a panoramic, undistorted field of view in a very thin package. The design consists of three planar layers of separately produced arrays, namely, a microlens array, a neuromorphic photodetector array, and a flexible printed circuit board that are stacked, cut, and curved to produce a mechanically flexible imager. Following this method, we have prototyped and characterized an artificial compound eye bearing a hemispherical field of view with embedded and programmable low-power signal processing, high temporal resolution, and local adaptation to illumination.
The prototyped artificial compound eye possesses several characteristics similar to the eye of the fruit fly Drosophila and other arthropod species. This design method opens up additional vistas for a broad range of applications in which wide field motion detection is at a premium, such as collision-free navigation of terrestrial and aerospace vehicles, and for the experimental testing of insect vision theories.
In reading about this device, I recalled the minute vision tubes that provided vision for the beetle-sized robotic UAV called the Scarab, from Raymond Z. Gallun's excellent 1936 short story of the same name:
...the Scarab buzzed into the great workroom as any intruding insect might, and sought the security of a shadowed corner. There it studied its surroundings, transmitting to its manipulator, far away now, all that it heard through its ear microphones and saw with its minute vision tubes.
