A headset for augmented reality applications is provided. The headset includes at least one eyepiece configured to provide a see-through image to a user via a transparent optical component, and to provide an artificial image through a display, and a dimming shutter configured to adjust a transparency level of the transparent optical component. The dimming shutter further includes an active liquid crystal layer configured to adjust a transparency level according to an electrical power provided between two electrodes, and a photoactive layer configured to adjust the transparency level upon absorption of an ultraviolet radiation for a selected period of time. A default orientation of a host material in the active liquid crystal layer may be in a dark state or in a clear state, when no electrical power is provided. A method and a memory storing instructions to execute the method for use of the above device are also provided.

This relates to systems and methods for measuring a concentration and type of substance in a sample at a sampling interface. The systems can include a light source, optics, one or more modulators, a reference, a detector, and a controller. The systems and methods disclosed can be capable of accounting for drift originating from the light source, one or more optics, and the detector by sharing one or more components between different measurement light paths. Additionally, the systems can be capable of differentiating between different types of drift and eliminating erroneous measurements due to stray light with the placement of one or more modulators between the light source and the sample or reference. Furthermore, the systems can be capable of detecting the substance along various locations and depths within the sample by mapping a detector pixel and a microoptics to the location and depth in the sample.

Embodiments described herein provide systems for stimulating a desired response, such as ovulation and egg laying, hunger, growth, mood and sexual maturity in birds, such as chickens, turkeys, ducks, quail and ostrich, by controlling the duty cycle, wavelength band and frequency of photon bursts to a bird, through the high frequency modulation of photons in an individual color spectrum to the bird and duty cycle, where the photon modulation and duty cycle is based upon the specific needs of the bird.

Disclosed herein are methods of tomographic imaging, the methods comprising emitting a beam of light from a light source to a sample and modulating the beam of light through a spatial light modulator configured to convert the beam of light to an Airy beam. The spatial light modulator can be rotatable and positioned at a first angle relative to the sample. The method can further obtain a first perspective view of the sample, rotate the spatial light modulator to a second angle relative to the sample, and obtain a second perspective view of the sample. Each of the perspective views can be generated by the Airy beam interacting with the sample on a focal plane. The method can then reconstruct a volumetric three-dimensional view of the sample using the first perspective view and the second perspective view.

A laser beam delivery apparatus for a microscope comprises first and second optical diffusers that are configured to move in a periodic manner with a respective different frequency. Each optical diffuser may comprise a spinning disk. The laser light is spatially randomized by the first spinning diffuser and its spatial pattern is further randomized by the second diffuser. The second diffuser prevents any spatial pattern from repeating after one revolution of the first diffuser, which prevents beating patterns from forming when the light is imaged through a spinning confocal disk and increases the uniformity in other cases.
