Systems and methods are described for a wide field of view (WFOV) optical doublet system. The system includes a first lens. The first lens has a first surface facing a viewer side of the system and a second surface facing away from the viewer side. The first lens has a positive refractive power. The system includes a second lens. The second lens has a first surface facing the first lens and a second surface facing away from the first lens. The second lens has a positive refractive power. The system includes a display panel. The display panel has a display surface facing the second surface of the second lens. The first lens, the second lens, and the display panel are configured in order from the viewer side along an optical axis of the system. Only one surface of either the first lens or the second lens is a diffractive surface and only two surfaces are Fresnel surfaces. In operation, light from an image displayed on the display surface enters the system through the second surface of the second lens and is magnified and presented in a system exit pupil. The system exit pupil is on the viewer side and a field of view presented to the viewer is at least eighty (80) degrees.

Wide field of view (WFOV) optical system and method

An eyepiece lens with protected Fresnel and diffractive surfaces. An eyepiece is provided with a first element having an optical axis and a diffractive structure comprising a plurality of diffraction facets formed on at least one surface of a first element, and a second element having a Fresnel structure comprising a plurality of Fresnel facets formed on at least one surface thereof, the respective draft angles of the Fresnel facets relative to the optical axis being proximate the respective incidence angles of their respective adjacent incident light rays of a nominal design so as to minimize light obscuration and scatter, the first element and the second element having essentially the same optical axis, the diffractive surface of the first element being adapted to compensate for chromatic dispersion introduced by the refractive properties of said first and second elements.

The present invention provides an optics assembly, a reflectometer, and a diagnostic device for providing quantitative measurement of optical radiation reflected from a sampling area on an assay matrix. The reflectometer includes an optical radiation source and a detector. The optical radiation source and the detector are mounted in a single plane. An optics assembly is configured to direct the illumination from the optical radiation source to the sampling area on the assay matrix and to direct the radiation diffusely reflected from the sampling area to the detector. The optics assembly is positioned over the face of the circuit board having the optical radiation source and detector mounted directly thereto. The present invention also provides a method for determining the presence of one or more selected analytes in a sample employing a plurality of sampling areas on one or more assay matrixes.

A diagnostics apparatus for detecting fluorescence events related to the presence of an analyte in a sample is disclosed. The apparatus includes a housing, a source of excitation light and a photodetector, and a unitary multi-surface optical module. The optical module is integrally formed and composed of an upstream portion having a focusing optical surface for directing excitation light from the light source to a focal region within an analyte-detection zone in the apparatus, and a downstream portion having a second focusing powered optical surface and at least one reflecting surface for directing fluorescence-emission light produced by fluorescence events within the detection zone, in a direction substantially normal to the path of the excitation light onto the photodetector. The optical module is adaptable to a variety of assay formats, including multiple-sample, sample-array, and disposable-cartridge formats.

The present invention provides a head-mounted display system that is compact and provides a wide field of view yet reduces or eliminates eyestrain. The system includes a binocular on-axis objective lens assembly that relays an image from a display device through a split-field exit aperture onto binocular optical paths. Intermediate image planes are formed within each optical path with each intermediate image plane having an associated microstructure that enhances the exit pupil of each left and right optical path.

Multi-channel optical detection system

A video interface linking a base station with a remote display, e.g., a head-mounted display, converts input video signals from NTSC or PAL formats into modulated video signals containing repetitive sequences of frame times with embedded audio and control signals. Each frame time includes equal consecutive color field times. Frame rates are converted by inserting selected repeating color frames into the datastream. Bursts of image information occupy a portion of each field time. During each data burst, the display is loaded with pixel luminance data. Between bursts, the display is illuminated by a color LED. Two video displays can be driven alternately, i.e., the first display loads while the second is illuminated. The modulated video signal can travel through the atmosphere on an infrared (IR) beam with a wavelength between 700 nm and 1100 nm. In one embodiment, the beam is scattered from a diffuse reflecting surface. Alternatively, the beam is emitted from an array of infrared light emitting diodes (LEDs). Designs for collecting lens assemblies are described. Some embodiments include return audio transmission.

An eyeglass-mount display (EMD) device includes a frame, a display pod, and a personalized module removably coupled to the frame. The frame has a cross-bracket and a pair of ear pieces each coupled to an end of the cross-bracket. The display pod is mounted to the cross-bracket and includes an electronic image generator for generating an image and optics for creating a virtual image. The personalized module includes preset fitting adjustments specific to a particular user. The module may also include corrective optical lenses.

Low-cost plastic optics allow biocular viewing of video images with a single electro-optic display device. Folded and unfolded dual off-axis configurations use collimated illumination and intermediate imaging optics to fill both eyepieces from a single display device without requiring beamsplitters. Multiple illumination schemes provide either monochrome or color, either two-dimensional or time-sequential true stereographic presentation. Light from multicolor sources is superimposed using dichroic mirrors. A display field lens proximate to the display surface collimates the illumination beam. A shaping lens provides substantially uniform illumination of the display surface. An aperture stop improves image quality by blending sub-pixel higher order spatial harmonics from the display device. Offsetting color over- and under-correction of individual optical elements provides overall chromatic correction with minimal optical complexity. Lightweight optical elements and injection-molded unitary plastic structures containing multiple optical elements reduce cost and complexity. A wireless video interface eliminates excess cabling.
