The present disclosure relates to optical systems, vehicles, and methods that are configured to illuminate and image a wide field of view of an environment. An example optical system includes a camera having an optical axis and an outer lens element disposed along the optical axis. The optical system also includes a plurality of illumination modules, each of which includes at least one light-emitter device configured to emit light along a respective emission axis and a secondary optical element optically coupled to the at least one light-emitter device. The secondary optical element is configured to provide a light emission pattern having an azimuthal angle extent of at least 170 degrees so as to illuminate a portion of an environment of the optical system.

An apparatus for skin imaging is provided. The apparatus is used in conjunction with a mobile device to obtain digital images using a digital camera and a light source provided by the mobile device. The apparatus includes an optical system for illuminating an object to be imaged with uniform ambient light and a light conduit for delivering reflected light to the mobile device digital camera. The apparatus is removably attachable to the mobile device and/or a mobile device case. One or more optical elements, such as lenses, films, filters, and light caps may be used to improve image quality and/or acquire magnified images.

Photographic lighting devices, systems, and methods having a plurality of electrical energy storage/discharge (EESD) elements and/or one or more light sources in a single photographic lighting device to perform one or more photographic lighting effects. EESD elements and one or more light sources can be configured to have multiple separate light emissions occur in a single image acquisition window. The multiple light emissions are separated in an image acquisition window by a time period that is about shutter speed exposure time/(N1), where N is the number of light emissions. In one such example, two light emissions are separated by a time period that is about shutter speed exposure time/(N1).

A flash system for an electronic device includes a ring-shaped light guide having a central opening. A camera lens is positioned in or behind the opening. A first light emitting diode (LED) is mounted on a printed circuit board (PCB), and the LED and PCB are encapsulated by a molded light guide of the flash system. An identical LED and PCB are encapsulated at an opposite end of the molded light guide (i.e., 180 degrees away). The back surfaces of each PCB diffusively reflects light from the LED on the other PCB. Light extraction features on the light guide surface uniformly leak out light from the LEDs. The light emission profile of the light guide has a peak axially aligned with the central opening of the light guide and rolls off to the edge of the camera's field of view.

Improvements in capturing an image of a cornea with Placido's disk lines is disclosed. The imaging is with a clam shell clamping device that is easily clamped onto a cellular device and the lighting tube is centered on the camera so the image at the end of the tube can be captured. The clamping device includes a ring light source that illuminates the outside of the tube. The tube has a plurality of geometrically spaced light and dark rings to create evenly spaced rings on the cornea. Imperfections in the cornea will distort the rings. The camera can capture the image and the image or picture can be forwarded to a doctor or other care giver to determine the perfection or imperfection of the cornea.

An inspection apparatus includes a portable housing and at least one handle structure integrally formed with the portable housing. The inspection apparatus further includes a vision data system, a lighting system, a user interface system, a wireless communication system, and a controller. The vision data system includes one or more cameras provided on the first face of the portable housing. The vision data system is operable to capture component data. The lighting system is arranged with the vision data system at the first face. The lighting system includes diffused light emitting diode (LED) ring arranged around at least one of the one or more cameras. The manufacturing inspection apparatus is a stand-alone and all-in-one computing device. The manufacturing inspection apparatus processes and stores inspection data locally.

A camera-puddle lamp integrated apparatus is disclosed. The apparatus comprising a lens module; an image sensor; a light source; and an optical unit, wherein the image sensor is spaced apart from a rear of the lens module so that the image sensor and the lens module are formed to operate as a camera, the light source is disposed to be coplanar with the image sensor and disposed at a peripheral portion of the image sensor, the optical unit is disposed in front of the light source so that light emitted from the light source is directed to a rear end of the lens module, and the camera-puddle lamp integrated apparatus is formed to operate as a puddle lamp by the light source and the optical unit.

Photographic lighting devices, systems, and methods having a plurality of electrical energy storage/discharge (EESD) elements and/or one or more light sources in a single photographic lighting device to perform one or more photographic lighting effects. EESD elements and one or more light sources can be configured to have multiple separate light emissions occur in a single image acquisition window. The multiple light emissions are separated in an image acquisition window by a time period that is about shutter speed exposure time/(N1), where N is the number of light emissions. In one such example, two light emissions are separated by a time period that is about shutter speed exposure time/(N1).

An illumination device comprises: an optical member that is provided with a circular ring-shaped or horseshoe-shaped light-guiding layer and diffusion layer, which are laminated in a central axis direction, the light-guiding layer having a light-entrance surface facing a tangential direction; and a light-introducing member that is disposed at the radially outer side of the optical member and that introduces illumination light into the light-guiding layer from the light-entrance surface, in the tangential direction; wherein the diffusion layer diffuses the illumination light entering from the light-guiding layer by volume scattering, and the optical member is formed, at least, of one end surface in the axial direction and emits the illumination light emitted from the diffusion layer.
