Embodiment 1

[0020] Embodiment 1, a multifunctional device suitable for solar image projection and shooting. Such as figure 1 As shown, it consists of an objective lens group 1, a beam splitter 2, a negative lens 3, a shooting window 4, a projection screen 5 and a device housing 6. The objective lens group 1 realizes the convergence of incident sunlight, and the objective lens group 1 may be composed of various forms of transmission optical lenses. The beam splitter 2 is used to separate the optical axes of the photographing optical path and the projection optical path, so that photographing and projection can be realized simultaneously. The beam splitter 2 can be a prism, or a beam splitting element in other structural forms. The first surface of the negative lens 3 is designed as a convex surface, coated with a spectroscopic film layer, so that part of the light is reflected and part of the light is transmitted. The negative lens 3 is placed inside the focal point of the objective len...

Abstract

Provided is a multifunctional device suitable for heliograph projecting and photographing. A human eye observing or projecting device is composed of an objective lens and a display screen. The multifunctional device is characterized in that an objective lens group, a beam splitter, a concave lens and a cell phone photographing window are arranged along the optical axis from outside to inside, anda projection screen is arranged on one side, perpendicular to the direction of the optical axis, of the light splitter. A cell phone / camera photographing light path is composed of the objective lens group, the light splitter and the concave lens; a cell phone / camera is placed on the photographing window, so the heliograph photographing function can be realized. A heliograph projecting light path is composed of the objective lens, the light splitter, the concave lens and the projecting screen, and an observer can see a clear amplified heliograph on the projection screen. By means of the multifunctional device, integral design is conducted on the heliograph projecting imaging and the cell phone / camera photographing imaging, multiple persons can watch the projected heliograph, and the photographing and recording requirements can also be met. The multifunctional device has the advantages of being simple in structure, convenient to carry and the like and can be widely applied in the sun science popularization education work.

Description

technical field [0001] The invention relates to a solar imaging and shooting device. The present invention is carried out under the support of the scientific research plan project of Shanghai Science and Technology Commission (project number: 15DZ1161803), and belongs to the field of optical measurement technology. Background technique [0002] For astronomy science workers and astronomy enthusiasts, the observation of solar images is a relatively common science display project. Traditional sun image observation methods mainly include visual observation, projection observation and photographic observation: [0003] Visual observation is mainly achieved through telescopes equipped with light reduction measures. This method is the most direct, but strict light reduction measures are required to protect the observer's eyes and avoid strong direct sunlight from causing damage to the observer's eyes. The disadvantage of this observation method is that the solar image data cann...
