Resolution Imaging

High-resolution imaging with a LaB6 instrument is limited by the spatial and temporal coherence, with little contrast remaining beyond the point resolution. A Field Emission Gun (FEG) reduces the incidence angle by a factor 5 to 10 and the energy spread by 2 to 3. Since the incidence angle is the dominant limitation for LaB6 the FEG provides a major improvement in contrast transfer, reducing the information limit to roughly one half of the point resolution. The strong improvement, predicted from high-resolution theory, can be seen readily in diffractograms (Fig. 1) and high-resolution images (Fig. 2). Even if the information in the image is limited deliberately to the point resolution by using an objective aperture, the improved contrast transfer close to the point resolution (Fig. 1) is already worthwhile.

Stimulus Time

Within the traditional notion of the senses, the perception of time is especially puzzling. There is no specific physical energy carrying information about time, and hence no sensory receptors can transduce a ‘temporal stimulus.’ Time-related properties of events can instead be shown to emerge from specific perceptual processes involving multisensory interactions. In this chapter, we will examine five such properties: the awareness that two events occur at the same time (simultaneity) or one after the other (succession); the coherent time-stamping of events despite inaccuracies and imprecisions in coding simultaneity and succession (temporal coherence); the awareness of the temporal extent occupied by events (duration); the organization of events in regular temporal units (rhythm).

AbstractWe introduce an unsupervised GAN-based model for shading photorealistic hair animations. Our model is much faster than previous rendering algorithms and produces fewer artifacts than other neural image translation methods. The main idea is to extend the Cycle-GAN structure to avoid semitransparent hair appearance and to exactly reproduce the interaction of the lights with the scene. We use two constraints to ensure temporal coherence and highlight stability. Our approach outperforms and is computationally more efficient than previous methods.
