Achromatic optical vortex lens.
A vortex lens is a useful optical device having applications ranging from astronomy to microscopy. Current vortex masks operate across a narrow bandwidth. Two design schemes are proposed for creating a vortex across a bandwidth exceeding 100 nm in the visible region of the spectrum.
متن کاملOptical Modeling of a Holographic Single Element Head-mounted Display
This paper proposes a new method to design an optically-fabricated holographic element, where the construction optical system and the playback system can be optimized jointly. The method was driven by the use of a new holographic recording material – the photo-thermo-refractive (PTR) glass that can only be written at 325nm, while its playback takes place in the visible part of the spectrum. App...
متن کاملFabrication of blazed holographic optical element by ultrahigh-precision cutting
A holographic optical element (HOE) is a kind of diffractive optical element. It can replace an optical system with multiple optical components such as lenses, mirrors, beamsplitters, and prisms. Thus, it is expected to be possible improve performance and reduce the number of optical parts of various optical systems, such as optical storage systems 1) like compact disk or digital versatile disk...
متن کاملFull-color lens-array holographic optical element for three-dimensional optical see-through augmented reality.
A novel system of optical see-through augmented reality (AR) is proposed by making use of a holographic optical element (HOE) with full-color and lens-array functions. The full-color lens-array HOE provides see-through property with three-dimensional (3D) virtual images, for it functions as a conventional lens array only for Bragg-matched lights. An HOE recording setup was built, and it recorde...
متن کاملModulated optical vortices.
Single-beam optical gradient force traps created by focusing helical modes of light are known as optical vortices. Modulating the helical pitch of such a mode's wave front yields a new class of optical traps whose dynamically reconfigurable intensity distributions provide new opportunities for controlling motion in mesoscopic systems. An implementation of modulated optical vortices based on the...
