Hybrid imaging systems for depth of focus extension with or without post-processing
Abstract : We address two different methods to enhance the depth of focus (DOF) according to the application, using amplitude and/or phase masks. The first application consists in increasing the length of the focal line of a lens while preserving its transverse resolution. We propose a mask inspired from holographic principles. We then address DOF enhancement with an hybrid imaging system composed of a pupil mask followed by a digital deconvolution step. We use an optimization criterion based on the final image quality to determine the optimal parameters of phase masks.
