Background

To achieve high precision assembly of the optical lens and screen, optical grade AA equipment assembly is typically required. In the field of VR optics module AA assembly, either a human eye-like camera (NED) or a matrix camera (Telescope) is generally used.

However, if either scheme is adopted, the technical process has advantages and disadvantages.

Human eye-simulated camera (NED) scheme:

the advantages are that: the single camera can cover the whole visual field of the picture of the VR module, and can directly test the overall brightness uniformity, optical Center (OC) and distortion of the VR module.

Disadvantages: because the depth of field of the lens of the near-to-eye camera is large, the AA peak value and the Virtual Image Distance (VID) cannot be accurately judged, so that the position of the AA cannot be accurately positioned, and the accuracy of the finally measured MTF result is poor.

Matrix camera (Telescope) scheme:

the advantages are that: multiple cameras, such as 0F,0.2F,0.3F,0.4F,0.5F,0.6F,0.7F,0.8F,0.9F,1F, etc., can be custom-defined. The MTF value of a single field of view can be accurately measured.

Disadvantages: the relation among the cameras needs to be calibrated, so that the difficulty is high; the luminance uniformity of the whole module cannot be tested.

Therefore, the AA device with a single camera has a certain limitation, and in the use process, two AA devices with different cameras are required to be combined at the same time, which greatly improves the production cost of enterprises, reduces the production efficiency of the enterprises, and can solve the problems if the two cameras are combined on the same device, and the conventional AA device is inconvenient to move.
