Embodiment 1

[0026] Embodiment 1: refer to figure 1 , the measuring bracket 2 is connected with the horizontal axis rotating table 31, the horizontal axis rotating table 31 is connected with the vertical axis rotating table 32, the vertical axis rotating table 32 is arranged on the three-axis translation table 33, and the three-axis moving table 33 is arranged on the base 4 The photoelectric measuring instrument 1 is arranged on the measurement support 2; the fixed support 62 is arranged on the base 4, wherein the virtual image display device connection plate 621 is connected with the three-axis translation frame 622, and the three-axis translation platform 622 is connected with the base 4; A virtual image display device 6 is provided on the image display device connecting plate 621; the virtual image display device 6 is positioned in front of the photoelectric measuring instrument 1; Perpendicular to the optical axis 10; the imaging lens 12 and the photoelectric detector 13 are all connec...

Embodiment 2

[0027] Embodiment 2: refer to figure 2 and image 3 , in the motion table 3, the vertical axis rotating table 32 is arranged on the three-axis translation table 33, the horizontal axis rotating table 31 is arranged on the vertical axis rotating table 32, and the horizontal axis rotating table 31 also includes two separate rotating shaft brackets 311; The photoelectric measuring instrument 1 is connected with the measuring support 2, and the measuring support 2 is connected with the horizontal axis turntable 31 through two separate rotating shaft brackets 311; the rotation axes of the horizontal axis turntable 31 and the vertical axis turntable 32 are orthogonal to the photoelectric measuring instrument 1 center of entrance pupil 11. During work, after the entrance pupil 11 of the photoelectric measuring instrument 1 enters the exit pupil of the virtual image display device 6, by rotating the horizontal axis rotating table 31 and the vertical axis rotating table 32, the photo...

Embodiment 3

[0028] Embodiment 3: refer to Figure 4 , the measurement support 2 is made up of " U " shape support 21 and center arm 20, and center arm 20 is connected with the bottom of " U " shape support 21; Connect; the separation distance between the arms on both sides of the "U" support is greater than the maximum lateral shell size of the virtual image display device 6; at this moment, the axis of the horizontal rotation axis and the axis of the vertical rotation axis are orthogonal to the rear 13mm of the entrance pupil 11. When working, due to the existence of the opening between the arms on both sides of the "U"-shaped bracket, the virtual image display device 6, especially some AR / VR glasses housings, is allowed to enter the opening between the arms on both sides, so that even if the exit pupils of these devices Concave inside its shell, the entrance pupil 11 can still be reached and accurately measured; at the same time, the axis of the horizontal rotation axis and the axis of ...

Abstract

The invention relates to an optical image measurement device, and particularly relates to a photoelectric measuring device for virtual image display equipment, which comprises a photoelectric measuring instrument, a measurement support, a moving table, a base and virtual image display equipment. The virtual image display equipment is in the front. The photoelectric measuring device for the virtualimage display equipment is characterized in that the photoelectric measuring instrument comprises an imaging lens, a photoelectric detector and a position adjusting device; the position adjusting device is connected with the imaging lens; and the position adjusting device is also connected with the photoelectric detector. The problem that the existing optical measuring device can not or is hard to measure the optical performance of the virtual image display equipment can be solved, and thus, a measuring device which can simulate eyes of a person more really and can accurately and convenientlymeasure the optical performance of the virtual image display equipment is provided.

Description

technical field [0001] The invention relates to an optical image measuring device, in particular to a photoelectric measuring device for virtual image display equipment. Background technique [0002] In modern society, the development of virtual imaging technology is becoming more and more perfect, and there are more and more virtual imaging devices, such as various AR and VR smart wearable devices, HUD devices in driving tools, and so on. Since the application fields of virtual image display devices are becoming more and more extensive and in-depth, coupled with the characteristics of virtual image display devices, that is, the image receiving end is often the eyes of human beings, the various optical properties of virtual image display devices measurement is becoming more and more important. [0003] Existing display image optical measurement devices, such as luminance meters, imaging colorimeters, etc., are measured by converging the optical signal of the measurement a...
