Modular ocular-free naked-eye 3D display lens cone

Abstract

The invention discloses a modular ocular-free naked-eye 3D display lens cone, and the lens cone comprises an objective lens group, a prism, an imaging lens group, a camera part, an image processing part, and a display part. The prism is exactly opposite to a light outlet of the objective lens group, and the imaging lens group is exactly opposite to a light outlet of the prism. The camera part is located at an outlet of the imaging lens group, and the image processing part is electrically connected with the camera part. The display part is electrically connected with the image processing part.The lens cone is advantageous in that the objective lens group, a pentaprism and the imaging lens group are used for dioptric imaging, and enable an image to be projected on an industrial camera; a data collection card is used for collecting the image, and a 3D touch display screen is used for presenting a 3D image of a target object; a user can directly observe the 3D image, thereby solving a problem that the image of the target object is out of sight during the application of an ocular lens; moreover, the lens cone solves a problem of fatigue, caused by the long-time fixed posture, of the user; the lens cone is simple in use method, does not need to carry out the complex adjustment, and is especially suitable for a green hand of a microscope.

Description

Technical field [0001] The invention relates to a microscope accessory, in particular to a modularized eyepiece-free naked-eye 3D display lens barrel. Background technique [0002] The lens barrel is an important part of the modern optical microscope observation system. It is a binocular telescope system composed of three parts: the objective lens, the image revolving system, and the eyepiece. Therefore, the lens barrel is generally called a binocular lens barrel. When using a microscope, the user observes the object scene through the eyepieces of the binocular tube. Since the binocular observation can produce stereo vision, people can see the scene image with a stereo sense. However, due to various aberrations in the optical system, it is impossible to completely eliminate this aberration. In addition, when people use the lens barrel to observe the target, they often have to keep their posture as unchanged as possible, so that their eyes are close to the exit pupil of the eyepie...

Problems solved by technology

However, due to the existence of various aberrations in the optical system, it is impossible to completely eliminate such aberrations. In addition, when people use the lens barrel to observe the target, they often have to keep their posture unchanged as much as possible, so that the eyes are close to the exit pupil of the eyepiece. point, lest the observed object jump out of the field of vision, which will lead to eye soreness, cervical fatigue, dizziness and other discomfort symptoms when observing the object for a long time. If things go on like this, it will also lead to occupational diseases.

For this reason, a binocular tube with adjustable inclination angle has appeared at present, which can adapt to the physical conditions of different users and the actual situation of the application environment, so that users can observe the target with the posture they feel most comfortable, thus improving to a certain extent The user's physical examination, however, this lens barrel still does not solve the shortcomings of the user needing to stare at the target for a long time to prevent it from running out of the field of vision

In addition, due to the differences in the interpupillary distance and diopter of the human eye, the binocular tube needs to be adjusted repeatedly before use to match the user's interpupillary distance and diopter. It is often difficult for untrained beginners to adjust the binocular tube

For example, if the binocular tube cannot be adjusted to match the user's interpupillary distance, double images will often appear when observing the eyepiece, which will aggravate symptoms such as eye soreness and dizziness
