The interpupillary distance is the distance between the binocular pupils of human eyes, the interpupillary distance of adults is usually 50-70mm, and for a virtual display image, the central sight line is defined as the connecting line of the image center (virtual image imaging position) of the binocular overlapping part and the pupil center. Referring to fig. 1(a) and 1(b), the calculation principle of the included angle between the left-eye waveguide plate and the right-eye waveguide plate in the binocular near-eye display device is shown, which can be easily derived from the geometric calculation theorem, and the calculation formula of the included angle between the left-eye waveguide plate and the right-eye waveguide plate is as follows:
Δθ＝|α-β|
where Δ θ represents an angle between the left-eye waveguide plate and the right-eye waveguide plate, α represents a lateral deflection angle of the left-eye waveguide plate, and β represents a lateral deflection angle of the right-eye waveguide plate.
And the geometric calculation theorem is also difficult to obtain, and the calculation formula of the binocular central sight line included angle is as follows:
wherein, theta represents a binocular central sight angle, L represents a pupil distance, and D represents a distance between a virtual image displayed by two eyes and two eyes.
That is to say, under the condition that the interpupillary distance L of the human eye is not changed, the included angle Δ θ between the left-eye waveguide sheet and the right-eye waveguide sheet is adjusted by adjusting the lateral deflection angle α of the left-eye waveguide sheet and/or the lateral deflection angle β of the right-eye waveguide sheet, and the binocular central sight line included angle θ can be changed to realize the adjustment of the virtual image imaging position (i.e., the depth of field), and when the included angle Δ θ between the left-eye waveguide sheet and the right-eye waveguide sheet infinitely tends to 180 °, the binocular central sight line included angle θ tends to 0 °, and the distance D (the depth of field) tends to infinity.
Further, angles between the light outgoing directions of the left-eye waveguide sheet and the right-eye waveguide sheet and between the left-eye waveguide sheet and the right-eye waveguide sheet are obtained, namely after an included angle delta theta between the left-eye waveguide sheet and the right-eye waveguide sheet is obtained through detection, a binocular central sight line included angle theta is obtained through calculation, and a distance D (depth of field) between a virtual image displayed in a binocular mode and the binoculars is obtained through calculation. For example, when the imaging light rays respectively exit perpendicularly from the left-eye waveguide sheet and the right-eye waveguide sheet, it is not difficult to obtain the imaging light rays by the geometric calculation theorem, and the sum of the included angle Δ θ between the left-eye waveguide sheet and the right-eye waveguide sheet and the binocular central sight line included angle θ is 180 °, and after the included angle Δ θ between the left-eye waveguide sheet and the right-eye waveguide sheet is detected, the binocular central sight line included angle θ and the distance D (depth of field) between the virtual image displayed by the two eyes and the two eyes can be obtained by calculation.
Based on the above principle, the present application provides a testing apparatus capable of adjusting and/or detecting an angle between a left-eye waveguide sheet and a right-eye waveguide sheet in a binocular near-eye display device to adjust or detect a depth of field of the binocular near-eye display device, the device comprises a laser collimator, a left eye optical machine, a right eye optical machine and a multi-axis regulator, wherein the laser collimator, the left eye optical machine and the right eye optical machine are arranged at the same height, the laser collimator is used for emitting laser, the left eye optical machine and the right eye optical machine are respectively used for placing a left eye waveguide sheet and a right eye waveguide sheet, the left eye waveguide sheet and the right eye waveguide sheet can reflect the laser, the laser collimator can also receive the reflected laser, the multi-axis regulator is integrated with the left eye optical machine and/or the right eye optical machine and used for regulating the deflection angle of the left eye waveguide sheet and/or the right eye waveguide sheet.
