As the demand for higher quality and higher resolution optical systems has become prevalent, both designers and
metrology scientists demand
mass production test stations for optical elements. Consequently, this technology is expected to be
standard procedure. Prior art's slow MTF measurement technique is expensive and inadequate for
mass production. Current proposed art will solve this and other important drawbacks by simultaneously testing multiple cameras. The proposed parallel testing method will be fast and accurate while meeting the market requirements and fulfill the growing need.This novel art will enable measuring MTF and other optical parameters in parallel formation within one
test station.The
Modulation Transfer Function (MTF) is an important aid which is necessary for
objective evaluation of the image-forming capability of optical systems. Not only that the MTF provides a means of expressing the
imaging quality of optical systems objectively and quantitatively, but it can be calculated from the lens
design data. Moreover, other parameters which are also very important, such as
field of view,
focal length and similar parameters can be measured by the proposed art.This technology allows optical and systems designers to predict and test reliably the performance of the optical systems. The manufacturers can compare the
image quality of the camera and lenses with the design expectations.Thus a method and apparatus are disclosed for fast parallel testing of multiple lenses or cameras.A unique electro optical design will be implemented to shift multiple optical elements in a synchronized matter while maintaining accuracy over a
wide field of view. The movement is angular over a wide angle and in two perpendicular directions—
pitch and
yaw. By design, each said optical element will perform its angular movement around the lens under test from remote. The center of rotation will be the central point of each lens input aperture. The apparatus is suitable for testing both camera and lenses simultaneously. The apparatus will preferably test lenses or cameras directly on the production floor.
