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.

A method of producing a Pepper's Ghost, includes projecting an image of a subject onto a reflective and transparent screen to create a virtual image of the subject alongside an object, the subject in the virtual image having a colour temperature. The object is illuminated with light having a colour and intensity that results in a colour temperature of the object at least approximately matching the colour temperature of the subject in the virtual image. The subject in the virtual image has a luminance and may be illuminated with light having a colour and intensity that results in a luminance of the object at least approximately matching the luminance of the subject in the virtual image.

This application provides a lighting accessory and a photographic lamp. The lighting accessory includes a light-transmission member, a light-shielding member and a connection assembly. The light-transmission member and the light-shielding member are both in a shape of a hollow cylinder. The light-transmission member includes a cylindrical first light-transmission surface and a flat second light-transmission surface blocked at one end of the first light-transmission surface. An inner cavity of the hollow cylinder of the light-transmission member is configured to accommodate a lamp body. The light-shielding member is arranged round an outer side of the first light-transmission surface and is spaced from the first light-transmission surface in a radial direction. The light-transmission member, the light-shielding member and the lamp body are connected through the connection assembly. The connection assembly also enables the light-emitting surface of the lamp body to be opposite to the first light-transmission surface.

A foldable reflector umbrella has a flexible, cloth-like reflective element with an outer supporting and tensioning structure composed of a plurality of tensioning spokes which are preferably distributed evenly over the expanse and divide the reflective element into a number of umbrella segments essentially corresponding to the number of tensioning spokes. With the reflector umbrella in the opened state, the reflective element consisting of the number of umbrella segments forms a substantially rotationally symmetrical body with a light exit opening. The reflector umbrella has a cloth-like reflective element in the opened state that is at least partially gathered so as to form an uneven reflection surface. A reflector assembly including a reflector umbrella is also provided.

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.
