Design of Compact Liquid Crystal on Silicon Projection Optics Utilizing a Common Freeform Optical Path for Augmented Reality Displays

Advanced Intelligent Systems, EarlyView.
This study presents a compact freeform projection optics using dual wedge prisms for waveguide displays. Unlike previous designs that separate illumination and imaging paths, a freeform optical path integrates both. The system achieves a 32º field of view, 37.5 pixels per degree, and a total volume of less than 2 cm3.

Optimized laser turrets for minimum phase distortion [PDF]

, 1980
An analysis and computer program which optimizes laser turret geometry to obtain minimum phase distortion is described. Phase distortion due to compressible, inviscid flow over small perturbation laser turrets in subsonic or supersonic flow is calculated.

Pancake Lenses through Curved Lamination for Compact Virtual Reality

Advanced Intelligent Systems, EarlyView.
This article presents an ultrathin VR optical system based on a 1.35 in. microdisplay, leveraging curved lamination technology. Compared to mainstream solutions, the proposed design demonstrates superior compactness (volume compression by 12%) and enhanced optical performance.

The Sine Condition in Relation to the Coma of Optical Systems [PDF]

Proceedings of the Physical Society of London, 1909
The condition for the correction of coma in a centred optical system is the well-known Sine condition. This has been proved by Clausius, Helmholtz, Hockin and others, and the importance of this condition in the design of optical systems has been pointed out by Abbe, Steinheil, Conrady, and others.

The coelurosaur theropods of the Romualdo formation, early Cretaceous (Aptian) of Brazil: Santanaraptor placidus meets Mirischia asymmetrica

The Anatomical Record, EarlyView.
Abstract The upper carbonate concretion levels of the Romualdo Formation (Aptian, Brazil) have yielded several theropod dinosaur remains, including spinosaurids and the coelurosaurs Santanaraptor placidus and Mirischia asymmetrica, the phylogenetic affinities of which are controversial.

“A lot of it is about feel”: The promise of sensory ethnography for anatomical education research

Anatomical Sciences Education, EarlyView.
Abstract Ethnographers have constructed rich accounts of cultural settings since the early nineteenth century. A new approach, sensory ethnography, holds great promise for Health Professions Education scholars in its incorporation of the senses, particularly regarding anatomical teaching and learning. In this article, we describe sensory ethnography as
