Problems solved by technology

At present, optical lenses mainly use plastic aspheric lenses or Fresnel lenses, and use injection molding technology to detect the quality of existing VR lens imaging, and use human eyes to observe the experience, which is subject to large subjective judgment factors and low efficiency. The quality cannot be guaranteed, so it is imminent to develop a device that can quantitatively detect the imaging quality of plastic aspheric lenses or Fresnel lenses

Abstract

The invention relates to optical detection equipment which comprises a supporting mechanism, an image collecting mechanism movably carried on the supporting mechanism, a target located next to the supporting mechanism and below the image collecting mechanism, a lens carrying device located between the image collecting mechanism and the target and a bearing mechanism located next to the target forbearing the lens bearing device and being capable of adjusting the position of the lens bearing device, wherein the supporting mechanism, the target and the supporting mechanism are successively arranged from left to right. The optical detection equipment is simple in structure, convenient and rapid in detection process, high in detection precision and low in cost.

Description

technical field [0001] The invention relates to an optical detection device, in particular to an optical detection device for detecting a virtual reality (Virtual reality) lens. Background technique [0002] Chinese patent 201510424415.6 discloses a grating-modulated lens defect automatic detection device and method. The lens defect automatic detection device modulated by the grating includes an image acquisition device, a camera fixing frame, a lens fixing frame, a grating, a linear screw guide rail, a plane backlight source and the like. In this grating modulation automatic detection device for lens defects, the image acquisition device is installed on the camera fixed frame, and the image acquisition device can only move along the lateral translation on the camera fixed frame. At the same time, the lens holder cannot be moved, and the position of the detected lens on the lens holder is fixed. The grating is installed on the linear screw guide rail and can only move alon...
