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 lighting apparatus for securing to differently dimensioned objects, in particular mobile devices, is intended to be provided. For this purpose, a lighting apparatus comprising an illuminant and a holding element is proposed, wherein the illuminant is secured to a first end section of a bistable element and the holding element is secured to a second end section of the bistable element, said second end section being situated opposite the first end section. The bistable element is rolled out in a first stable state, such that the illuminant is at a maximum distance from the holding element. The bistable element is rolled together in a second stable state. The lighting apparatus is clampable to the mobile device by spring force of the bistable element.

An imaging unit of the disclosure includes: a camera; a holding member configured to hold an imaging target object to be imaged by the camera; a light irradiation device configured to irradiate lights of different wavelengths from multiple light sources towards the imaging target object held by the holding member; and a control device configured to obtain a proper resolving power value for a light or lights of one or more light sources selected from the multiple light sources for use for imaging, irradiate the light or lights of the one or more light sources so selected onto the imaging target object to image the imaging target object using the camera, and make use of the proper resolving power value in processing an image obtained from the camera.

A flashlight camera system. The flashlight camera system includes a housing having a first portion and a second portion, wherein a light source is disposed on the first portion. A camera is disposed on the first portion at a distal end of the first portion. A motion sensor is operably connected to the camera and the light source, wherein the camera and the light source are activated when the motion sensor detects motion. A power source is disposed within the housing and is operably connected to each of the light source, the camera, and the motion sensor. The second portion includes a handle thereon.

A monitoring camera having a compound window arranged in a frame of a camera housing, and a camera head arranged inside the housing, is disclosed. The compound window has an inner transparent plate, closest to the camera head, and an outer protective window, arranged in a plane parallel to the transparent plate, on an outside thereof, and the compound window further comprises a heating arrangement arranged and configured to supply thermal energy to peripheral areas of the transparent plate. The transparent plate has a greater heat conductivity than the protective window and is arranged in close proximity to the protective window, so thermal energy will be transferred from the heating arrangement to the transparent plate and then efficiently transferred to the protective window.

This invention provides a vision system with an exchangeable illumination assembly that allows for increased versatility in the type and configuration of illumination supplied to the system without altering the underlying optics, sensor, vision processor, or the associated housing. The vision system housing includes a front plate that optionally includes a plurality of mounting bases for accepting different types of lenses, and a connector that allows removable interconnection with the illustrative illumination assembly. The illumination assembly includes a cover that is light transmissive. The cover encloses an illumination component that can include a plurality of lighting elements that surround an aperture through which received light rays from the imaged scene pass through to the lens. The arrangement of lighting elements is highly variable and the user can be supplied with an illumination assembly that best suits its needs without need to change the vision system processor, sensor or housing.

An evidence capturing device, which includes an elongate tubular body having a first object end and a second, camera mounting, end, with an optical path defined between the object end and the camera mounting end, a bracket at the camera mounting end of the body for mounting a camera to the body, so that a mounted camera is directed towards the object end of the body at which an object plane is defined perpendicular to the body, a filter holder disposed in the optical path between the object end and the camera end, a light source housing protruding from the body between the object end and the camera end for mounting a light source so that a mounted light source is directed at the object plane from an angle and a rotatable ring for rotating the camera and light source housing relative to each other about an elongate axis of the body.

An apparatus for a mobile light source is described. The apparatus comprising: a first outer casing housing an array of lights, wherein the array of lights are located on a surface of a substrate, a second outer casing coupled with the first outer casing to create an enclosure that is substantially water tight, a heat shield composed of a metal alloy creating two compartments in the enclosure such that the array of lights is situated in a first compartment, and a printed circuit board (PCB) with circuitry for controlling the array of lights, the PCB situated in the second compartment of the enclosure housed by the second outer casing, and wherein a surface the PCB is substantially parallel to the surface of the substrate.
