Abstract

A relief image focusing system is proposed here, contrary to the normal focusing systems using a flat image. The relief is mapping the panorama's depth by a scale depending on the objective parameters. Opposite to normal understanding, the relief is not static. It is formed synchronously with the forward-backward linear motion of the objective. Each pixel of the vision sensor is illuminated and interference of light waves takes place. As the objective moves, the intensity of the interfered optical signal changes between the internal sensor noise level and certain maximum as a function of time. The process of forming the signal in the relief image space is based on searching extremes of interfered optical signals at each pixel. A method of mapping the measurement scale of a monocular focusing distance-meter is presented in the paper. It is implemented by sampling the signals, digital measurement of the time intervals and the signals' amplitudes and joint processing of the obtained numerical values providing a limited error to portions of micron. The method contributes the vision systems to perceive panoramic view in wide distance ranges. It can work at a wide range of optical signals and is invariant to aberrations.
