A marine vessel includes a vessel body including a navigation light, an imager provided in a vicinity of or adjacent to the navigation light, and a light shield provided between the navigation light and the imager so as to block light from the navigation light to the imager.

The present invention is directed to a rotatable platform riser system used for capturing imagery of objects from one angle or multiple angles with a seamless pure white background without reflections or shadows. The rotatable platform riser system comprises a turntable platform; a rotatory drive mechanism operably coupled to the turntable platform for rotating the turntable platform along its vertical axis; a riser comprising a substantially round open top and a substantially round bottom, an upright wall extending from the bottom to the top defining volume of the riser, the riser mounted or resting on the turntable platform at the bottom; and a riser platform having a top surface and a bottom surface, the riser platform having a diameter same or larger than the diameter of the top of the riser, the riser platform mounted or resting over the top of the riser.

A softbox having a body with an integrated light-altering element. The light-altering element may have a body and an edge, where at least a portion of the edge of the light altering element is non-removably coupled to at least a portion of softbox body proximate to the softbox edge. The other portions of the edge may have attachment elements that couple to other portions of the distal edge of the softbox. Another light-altering element, such as a grid, may couple to the softbox by coupling to a cuff of the body of the softbox.

A contactless type optical device includes an image photographing module configured to photograph a subject, the image photographing module including a photographing lens forming an image of light that is scattered from the subject and is incident on the photographing lens; an illuminator configured to radiate illumination light, the illuminator being disposed within a predetermined distance from the image photographing module; a first lens configured to reduce an incidence angle of the illumination light traveling from the illuminator; and a second lens having a first surface to which the illumination light passing through the first lens is incident to be transmitted, and a second surface to which the subject's scattered light scattered from the subject is incident to be transmitted. The photographing lens is disposed such that the subject's scattered light passing through the second lens is incident on the photographing lens.

The invention refers to a lighting device comprising at least one light emitting diode (LED). The object to provide a lighting device that is capable of providing a light pattern for illuminating an object in 3D imaging, wherein the lighting device is simple and cost-effective to manufacture, while the lighting device may in addition have a very small form factor, is solved in with a lighting device comprising: at least one LED for emitting light towards a light-emitting side; a first grating with a regular pitch having light-blocking sections and light-permeable sections; wherein the first grating is arranged on the light-emitting side to block the passage of light at the light-blocking sections, such that the light passing the light-permeable sections is capable to illuminate an object with a line pattern. The invention further corresponds to a method for producing a lighting device and the use of a lighting device.

A depth camera assembly (DCA) for depth sensing of a local area includes a structured light generator, an imaging device, and a controller. The structured light generator illuminates the local area with a structured light pattern. The structured light generator includes a programmable diffractive optical element (PDOE) that generates diffracted scanning beams using optical beams. The PDOE functions as a dynamic diffraction grating that dynamically adjusts diffraction of the optical beams to generate the diffracted scanning beams of different patterns. The diffracted scanning beams are projected as the structured light pattern into the local area, wherein the structured light pattern is dynamically adjustable based on the PDOE. The imaging device captures image(s) of at least a portion of the structured light pattern reflected from object(s) in the local area. The controller determines depth information for the object(s) based on the captured image(s).
