Fog-penetrating telescope

Abstract

The invention relates to a through-frog telescope which comprises a three-variable focus objective, a band switching circuit, an imaging detector circuit, a scieropia processing circuit, a display processing circuit, an operation panel circuit and a display interface circuit. The scieropia processing circuit is used for receiving a control command of the operation panel circuit, then analyzing and judging categories of the control command, and sending out a corresponding control command to the band switching circuit. A common filter disc or a band switching disc operates to determine the scieropia processing circuit to operate in a state of an original drawing or a state of a scieropia image. The display processing circuit receives the control command of the scieropia processing circuit to determine output of the image is in an internal output mode or an external output way, wherein the image is internally-output to an eyepiece, and externally-output to a display interface to be connected into a displayer. The operation panel circuit sends out a control command of focus changing to drive actions of focal distance of three-variable focus objective. Therefore, the through-frog telescope improves adaptive capacity and application range of telescope products.

Description

technical field [0001] The invention relates to an optical imaging technology, and mainly provides a fog-penetrating telescope. Background technique [0002] An optical telescope is an optical instrument that uses concave and convex lenses to observe distant objects. The refraction of the light through the lens or the reflection of the light by the concave mirror make it enter the small hole and converge into an image, and then pass through a magnifying eyepiece to be seen. The first function of the telescope is to enlarge the opening angle of distant objects, so that the human eye can see details with smaller angular distances. The second function of the telescope is to send the light beam collected by the objective lens that is much thicker than the diameter of the pupil (up to 8 mm) into the human eye, so that the observer can see faint objects that were originally invisible. [0003] The imaging quality of optical telescopes is greatly affected by the visibility of the...

Problems solved by technology

[0005] This shows that the above-mentioned existing optical telescope obviously still has inconvenience and defects in structure and use, and needs to be further improved urgently.

In order to solve the above-mentioned problems, the relevant manufacturers have tried their best to find a solution, but for a long time no suitable design has been developed, and the general product has no suitable structure to solve the above-mentioned problems. This is obviously the relevant industry. Urgent problem
