Effective data collection aperture in long-wavelength imaging systems
Abstract
A new configuration for the acquisition of data in long-wavelength imaging systems is described and is shown to optimise the data collection capabilities of the aperture used. The feasibility of the approach has been demonstrated at a free-space ultrasonic frequency of 40 kHz and typical imagery is presented.
