Multifunctional device suitable for heliograph projecting and photographing

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 photographing device suitable for solar imaging. The invention was carried out under the funding of the scientific research project of the Shanghai Municipal 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 the sun is a relatively common science demonstration project. Traditional solar image observation methods mainly include visual observation, projection observation and photographic observation: [0003] Visual observation is mainly achieved through telescopes equipped with dimming measures. This method is the most direct, but requires strict dimming measures to protect the observer's eyes and avoid strong direct sunlight from damaging the observer's eyes. The disadvantage of this observation method is that the solar image data cannot be saved, whic...
