A lighting device that is capable of retracting a reflective member inside a lighting device and of deciding size of the reflective member irrespective of the size of the lighting device. The lighting device includes a light emitting section and a reflective member. The reflective member is drawably retracted in the light emitting section and is provided with reflectors that are developed by a drawing operation to reflect a part of light irradiated from the light emitting section. Area of the reflectors in a developed state is more than area of the reflectors in a retracted state.

An infrared imaging system includes a detector configured to detect wavelengths in a first infrared wavelength band and a second infrared wavelength band, shorter than the first infrared wavelength band, wherein the second infrared wavelength band is an extended short wavelength infrared band; and a light source configured to output light in the second infrared wavelength band to an object radiating the first infrared wavelength.

An imaging device having an imaging field of view, the imaging device including at least one illumination port configured to output light for illuminating a target; an imaging sensor to detect light traveling along an optical path to the imaging sensor; and a first movable window positioned upstream of the sensor with respect to a direction of travel of light along the optical path, wherein the first movable window is configured to move into the optical path in a deployed position for modifying light received from the target.

A technique for strobe shooting using automatic irradiation direction control. A strobe device includes a light emission section that emits light, and a drive unit that changes an irradiation direction of light emitted from the light emission section. Exposure conditions set to the camera are notified to the strobe device, and light emission conditions are set according to the exposure conditions. The irradiation direction of light emitted from the light emission section is determined based on the exposure conditions and the light emission conditions.

Provided herein are imaging devices and methods of use thereof, the imaging devices comprising at least one illumination port configured to output light for illuminating a target; an imaging sensor assembly configured to detect light traveling to the imaging sensor assembly; and at least one drape sensor configured to detect a drape mounted to the device.

In a thin flash module for a camera, a rectangular array of LEDs is mounted on a single lead frame. The lead frame connects the LEDs in series. The LEDs are much smaller than conventional LEDs in a flash module. The LEDs may be in 53 array or a 43 array, for example. An array of reflective cups is molded over the lead frame or attached to the lead frame, where each of the cups has a substantially square aperture to produce a square sub-beam. A layer of phosphor is located within each cup overlying its associated LED to produce white light. The aspect ratio of the array is selected to generally match the aspect ratio of the camera's field of view (e.g., 16:9). Since the LEDs are very small, the height of the cups may be small to form an ultra-thin flash module. Thin lenses may instead be used.

An illumination device for illuminating a camera's field of view, including a light source, and a reflector unit having reflecting sections is provided. Each reflecting section is associated with a light distribution, wherein the light distributions for different reflecting sections are different. The reflector unit is arranged such that light emitted by the light source is deflected by one of said reflecting sections being selected based on the camera's field of view. A method for illuminating a camera's field of view is also provided.

A speed ring can be used to attach a light diffuser, such as a soft box, to a photographic lighting apparatus. For example, the speed ring can couple a light diffuser to a lamp housing of a photographic lighting system. The speed ring may have an overall rectangular appearance, such as a square appearance, and may be described generally as a rectangular frame, such as a square frame, with special adaptations to attach a light diffuser to a photographic lighting apparatus.

A high speed photography system and method. The system and method use a split beam laser which is recombined after passing through an image then passed through a scanning apparatus, such as a rotating mirror, to form an image upon construction by a frame alignment algorithm. The image may be a 3D image. The system and/or method of constructing an image may use a plurality of laser beams as sourced from a single split beam or as sourced from a plurality of lasers.

A light source angle-adjustment device is adapted to be disposed adjacent to a camera lens and includes a light-emitting member, a reflecting member, and a driving member. The light-emitting member has a light outlet. A light of the light-emitting member is emitted from the light outlet along a light path. The light outlet faces away from the camera lens and faces the reflecting member. The reflecting member is disposed in the light path of the light-emitting member. The reflecting member has a reflecting surface reflecting the light emitted by the light-emitting member. The driving member is connected to the reflecting member and drives the reflecting member to rotate around an axis to change an angle provided between the light path and the reflecting surface.
