A drape configured to cover a handheld imager for use in a medical procedure, the drape including a frame that is removably mountable to a front portion of an enclosure of the imager; and at least one light transmissive component mounted to the frame and recessed with respect to a front of the frame such that the at least one light transmissive component is positioned in front of at least one enclosure window of the imager when the frame is mounted to the front portion of the imager.

A case for use in association with an electronic device having a camera system with a flash that can serve as a flashlight, including: (a) a case body, wherein the case body is adapted to releasably retain the electronic device; and (b) a cover member, wherein the cover member is adapted to enable a person to use the flash of the camera system as a flashlight while simultaneously preserving his/her night vision.

A light-emitting device includes: a plurality of light-emitting elements arranged in an array on a base member; and a compound eye lens that includes a plurality of lens parts disposed above the base member and facing the plurality of light-emitting elements. The plurality of light-emitting elements are arranged such that each of the plurality of light-emitting elements faces a corresponding one of the lens parts, and a center of each of the plurality of light-emitting elements is offset from a lens center of the corresponding one of the lens parts of the compound eye lens in a direction toward a center of the compound eye lens in a plan view. The plurality of light-emitting elements include first light-emitting elements and second light-emitting elements that are alternately arranged, wherein an emission color of the first light-emitting elements is different from an emission color of the second light-emitting elements.

An oral photography system and method can include: a chassis, the chassis including a chassis base and a vertical chassis extension, the vertical chassis extension extending upward from the chassis base, and the vertical chassis extension including: a magnetic clamp having a first clamping element for securing an imaging device to the vertical chassis extension, the imaging device including a second clamping element, a diffusion panel attachment coupled to the vertical chassis extension, and a light panel attachment coupled to the vertical chassis extension; a diffusion panel releasably affixed to the diffusion panel attachment; and a light panel releasably affixed to the light panel attachment.

Apparatus for obtaining polarized imagery using a portable device, comprising a light source, a first polarizing filter configured to cover the light source, a second polarizing filter configured to cover the lens of a mobile device's built-in camera, one or more housing to contain the light source and filters, and couplers attached to the housings for coupling the housings to the mobile device. When the housing is coupled to the mobile device and the camera is operated, light from the light source passes through the first polarizing filter, then passes as polarized light through an illuminating path to illuminate an object being imaged. Then light from the illuminated object passes through an optical path, through the second polarizing filter to the camera lens. In embodiments, the axis of polarization of at least one of the polarizing filters can be modified to allow for cross, parallel and variable polarized imaging.

A light-emitting device includes: a light-emitting unit having a light-emitting surface; a light guide member configured to guide light from the light-emitting unit, the light guide member having a first surface that includes an incident portion on which light from the light-emitting unit is incident, and a second surface from which the light exits, the second surface including a plurality of concentric protrusions; and a movement mechanism configured to move the light guide member such that the incident portion and the plurality of concentric protrusions move together relative to the light-emitting unit in a first direction that intersects a center axis of the light-emitting surface.

An imaging apparatus includes an imaging element, a lens unit that focuses light on the imaging element, and a light source disposed around the lens unit. The lens unit includes a blocking part that projects over a region located around the lens unit and facing the light source so as to block stray light from the light source.
