One point-detector imitates facet in ommateum , image detector imitates one whole ommateum , and it's visual function. Object's 3-D information is got using two point-detectors.

The shape of the detector must match the varying curvature of the image surface to accommodate continuously adjustable zoom, and this is easily done with this new hemispherical eye camera.

To achieve an in-focus and magnified image, the researchers actuate the hydraulics to change the curvatures of the lens and detector in a coordinated manner.
