Abstract: An apparatus for measuring the MTF or another optical property of an optical system includes an object to be imaged, which has a plurality of structures arranged in a plane and separated from one another, a two-dimensional image sensor, and collecting optics having a focal length f. The image sensor has a distance a from the collecting optics with 0.94·f?a?1.1·f. A holder for the optical system is arranged such that the optical system is located in a beam path between the object and the collecting optics. The image sensor and the collecting optics are configured such that all structures can be imaged by the optical system and the collecting optics onto the image sensor simultaneously.

Abstract: A measuring apparatus for measuring a modulation transfer function (MTF) of an afocal optical system has a receiving device, a light-providing device, a camera, at least one further light-providing device, at least one further camera, and a transmission interface. In an operational state, the light-providing device, the afocal optical system, and the camera are arranged coaxially on or with measurement axes parallel to a measuring axis oriented perpendicularly to the receiving plane. The further light-providing device, the afocal optical system, and the further camera are arranged coaxially on or with measurement axes parallel to an oblique measuring axis oriented obliquely to the measuring axis. An evaluation unit is configured to identify, using at least one camera image, the modulation transfer function of the afocal optical system.

Abstract: A system, method, and non-transitory computer-readable medium are provided for creating a freeform field of view mask for a camera in a vehicle to increase the field of view of the camera during operation of the vehicle. The camera captures an image of a portion of the vehicle in front of a calibration screen. A processor includes logic that applies a blurring filter to the captured image to create a blurred image, determines a freeform boundary of a field of view of the camera in the blurred image, creates a field of view mask based on the freeform boundary; and applies the field of view mask to the camera for maximizing the field of view of the camera during operation of the vehicle.
