Introduced here are multi-channel light sources able to produce a broad range of electromagnetic radiation. A multi-channel light source (also referred to as a “multi-channel emitter”) can be designed to produce visible light and/or non-visible light. For example, some embodiments of the multi-channel light source include illuminant(s) capable of emitting electromagnetic radiation within the visible range and illuminant(s) capable of emitting electromagnetic radiation in a non-visible range, such as the ultraviolet range or infrared range. By capturing images in conjunction with the visible and non-visible light, additional information on the ambient scene can be gleaned which may be useful, for example, during post-processing.

Disclosed are a disturbance light identifying apparatus, a disturbance light separating apparatus, a disturbance light identifying method, and a disturbance light separating method capable of precisely identifying whether or not light exiting an optical system contains a disturbance light component or capable of separating such a disturbance light component by using a simple technique. Provided are: a modulated light irradiation unit that irradiates an optical system 1 with modulated light; a light receiving unit that receives light exiting the optical system 1 in response to an incidence of the modulated light from the modulated light irradiation unit; and a controlling unit that controls the modulated light irradiation unit and the light receiving unit.

A camera includes: (a) a printed circuit board supporting a first circuit component; (b) a second printed circuit board; (c) a PCB holder for holding the printed circuit boards spaced apart from each other and pivotable relative to each other; and (d) a housing for enclosing the printed circuit boards and the PCB holder, the PCB holder being dimensioned for fastening to the housing such that the printed circuit boards are not parallel to each other and the first circuit component is placed in thermal communication with the housing.

An image processing apparatus according to the present invention includes: input means for inputting a distance information distribution calculated from an image captured by using an optical system that forms a field image on an imaging element of imaging means; estimation means for estimating a depth direction in the image from an imaging condition of the imaging means; and decision means for deciding, from a relationship between the distance information distribution and the estimated depth direction, an evaluation value indicating a deviation degree of the optical system and the imaging element from design positions.

A portable optic metrology thermal chamber module including a housing defining a thermal chamber, with a thermally isolated environment arranged for holding an optic device under test, the housing having an optic stimulus entry aperture configured for entry of a stimulus beam, from a metrology system stimulus source through the entry aperture onto an entry pupil of the device to an image analyzer, and a module mount coupling to modularly mount the portable optic metrology thermal chamber module to a support of a metrology system of the metrology system stimulus source so as to removably couple the portable optic metrology thermal chamber module as a unit to the support in a predetermined position relative to the metrology system stimulus source, and the housing is sized and shaped so that the portable optic metrology thermal chamber module is portable as a unit for moving to and removing from the predetermined position.

The techniques of this disclosure relate to determining an optical characteristic of a camera. The device includes a housing that receives a test fixture retaining a camera. The housing includes a first segment and a second segment creating a chamber surrounding the camera. The first segment is attached to the test fixture and defines a first orifice located in a side of the first segment. The first orifice directs a flow of a gas out of the chamber. The second segment defines a second orifice located in a first side of the second segment to direct the flow of the gas into the chamber. An aperture is located in a second side of the second segment and positioned opposite the test fixture to define a field of view that includes a camera target. The aperture receives a lens barrel of the camera and enables the determination of the optical characteristic.

Methods, systems, and apparatus for a stray-light testing apparatus. In one aspect, the apparatus includes an optical assembly including a spatially extended light source and one or more optical elements arranged to direct light from the spatially extended light source along an optical path, a moveable frame supporting the optical assembly including one or more adjustable alignment features for guiding positioning of the stray-light testing apparatus relative to an onboard camera on a vehicle, and a shrouding mechanism attached to the frame and positioned on the frame such that, when the stray-light testing apparatus is aligned relative to the onboard camera on the vehicle and the optical path of the optical assembly is within the field of view of the onboard camera, ambient light exposure for the onboard camera is below a threshold.
