Real time modulable multifocality through annular optical elements.
We present and analyze new multifocal optical elements based on an annular distribution of the transmittance. These elements provide selectable number of foci and can be designed to work between two fixed positions or even to provide extended focal depth. The energy of the foci can be modulated through a single parameter that controls the area of each ring. In our study we analyze the quality o...
متن کاملReal-time hyperspectral imaging with volume holographic optical elements
We report a novel hyperspectral optical sensor capable of providing image information with four degrees of freedom (4D), i.e. volumetric spatial information and spectral information simultaneously, in real time. The imaging principle is based on the diffraction properties of volume holographic optical elements designed as spatial-spectral filters. The 4D imager can be configured to image object...
متن کاملReal - Time Quantized Optical
Algorithms based on the correlation of image patches can be robust in practice but are computation-ally intensive due to the computational complexity of their search-based nature. Performing the search over time instead of over space is linear in nature, rather than quadratic, and results in a very eecient algorithm. This, combined with implementations which are highly eecient on standard compu...
متن کاملBayesian Real-time Optical Flow
Optical flow can be used to compute motion detection, time to collision, structure, focus of expansion as well as object segmentation. Unfortunately, most optical flow techniques do not provide accurate and dense measures that are useful for these types of computations. In addition, most techniques are also slow computationally. Albeit, one method proposed by Camus is able to perform optical fl...
