The present disclosure relates to cantilevered imaging modality wearable optical systems that provide for optimal ergonomics coupled with vision enhancement and vision magnification. Methods of use, devices, and kits are also contemplated.

An image display device is capable of easily adjusting a diopter scale with respect to a virtual image. The image display device includes an image generating unit that emits image light including image information, a first optical system that forms an intermediate image by condensing the image light, a second optical system that guides a virtual image to eyes of a viewer by deflecting the light from the intermediate image, and guides the light to the eyes of the viewer by transmitting external light, and an intermediate image position changing device that adjusts a position of the virtual image in depth direction by changing a position of the intermediate image.

An imaging system for a smartphone includes a housing configured to rigidly attach to a handheld smartphone device. The system further includes an arm extending from the housing, wherein the arm is configured to be adjustable such that the arm is movable toward and away from the housing. Additionally, the system includes a sample mounting portion attached to the arm, the mounting portion having a retaining device, wherein the retaining device is configured to secure a target sample, the mounting portion configured to direct an image of the target sample to a first camera in the handheld smartphone device.

Head-mounted display systems and methods of operation that allow users to couple and decouple a portable electronic device such as a handheld portable electronic device with a separate head-mounted device (e.g., temporarily integrates the separate devices into a single unit) are disclosed. The portable electronic may be physically coupled to the head-mounted device such that the portable electronic device can be worn on the user's head. The portable electronic device may be operatively coupled to the head-mounted device such that the portable electronic device and head mounted device can communicate and operate with one another. Each device may be allowed to extend its features and/or services to the other device for the purpose of enhancing, increasing and/or eliminating redundant functions between the head-mounted device and the portable electronic device.

A head mounted display system comprises a main body configured to be worn on a human head and to secure therein a mobile computing device having a display and hardware for generating images on the display corresponding to motion data. The system further includes a remote controller, distinct from, but in communication with, the mobile computing device, which when detachably attached to the exterior of the main body provides the motion data to the mobile computing device that is used by the mobile computing device in performing head tracking of the human head, the remote controller incorporating a remote controller processor, at least one motion sensor for providing the motion data

There is provided an imaging device, the imaging device including: a support structure configured to be mountable on a head of a user; an optical filter having a reflection surface that reflects predetermined light having a predetermined wavelength band and allows visible light to pass; and at least one first imaging unit configured to acquire a first image including at least a part of a face of the user on the basis of the predetermined light reflected by the reflection surface.

Disclosed herein are techniques for adjusting the interpupillary distance (IPD) of an optical device. A system for IPD adjustment includes a first nonmoving component, a sliding assembly comprising a button, and a pair of magnets, wherein a first magnet of the pair of magnets is coupled to the sliding assembly. The pair of magnets is configured to exert a magnetic force on the sliding assembly in a first direction to press the sliding assembly against the first nonmoving component to lock the sliding assembly to the first nonmoving component. The sliding assembly is configured to, when the button of the sliding assembly is pushed by a force in a second direction opposite the first direction of the magnetic force, disengage with the first nonmoving component and become slidable with respect to the first nonmoving component.

To provide a composite diffraction element capable of preventing nonuniformity of an image due to, for example, a bubble and improving quality. A composite diffraction element 100 includes: at least two diffraction elements 101 and 102 each having a reflection surface that reflects light; and a support body 103 placed between each of the diffraction elements 101 and 102, the support body 103 having a void 108, and each of the diffraction elements 101 and 102 are placed, facing each other across the void 108. Furthermore, in the composite diffraction element 100, the diffraction elements 101 and 102 are reflective diffraction elements, and transmit projected light while diffracting the projected light selectively. The diffraction elements 101 and 102 are volume hologram elements having protective layers 104 and 106, and photosensitive material layers 105 and 107 on each of which the reflection surface is formed.

A pipette comprising a cylinder with a piston movable inside the cylinder for aspiring and dispensing liquid, and a handle portion for gripping the pipette, wherein the pipette further comprises an imaging device element for obtaining images that assist the use of the pipette.
