摘要： 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.

摘要： A device for checking the refractive power distribution and/or centering of a spectacle lens is disclosed. The device includes a holder for arranging the spectacle lens in a measuring position, a display device for displaying a test structure, and an image capture device for capturing an actual image of the test structure for an imaging beam passing through the spectacle lens arranged in the measurement position. The display device simultaneously displays the captured actual image and a target complement image complementary to a target image of the test structure, wherein the target image of the test structure is that image which would arise for an imaging beam passing through a spectacle lens, arranged in a predefined target measuring position, with a predefined target refractive power distribution. The corresponding method for checking the refractive power distribution and/or centering of a spectacle lens is also disclosed.

摘要： Systems and related methods are provided to perform optical characterization of system under tests (SUT), including one or more optical elements (OE), for various purposes including evaluation of optical resolution needed to distinguish image elements, blur, line of sight jitter, and/or pointing stability. Various testing systems and methods are provided including an embodiment having a vibration loading system (VLS), a first acceleration sensor coupled with the VLS, and a mounting structure adapted to receive the SUT. An illumination target system (ITS) emits light that passes through the SUT OE's lens and is captured by the SUT's imaging system. A light control system controls the ITS based on a plurality of activation commands and a Test Control System (TCS). The TCS receives ITS input through the SUT that is synchronized with acceleration sensor data (e.g. phase of VLS position) and analyzed via real-time or post-processing.
