Description

[0001] The present invention relates to the technical field of telescopes, and in particular to a reflecting telescope for enhancing images. Background Art

[0002] A Newtonian reflecting telescope is an optical telescope that uses a concave reflecting primary mirror and a flat reflecting secondary mirror to reflect light and form an image. Newtonian reflecting telescopes are widely used in popular science telescopes because of their simple optical system and low cost.

[0003] However, when observing stars, deep-sky objects, artificial satellites, and other faint solar system objects, since these objects have fewer details and are relatively faint, observers cannot obtain more detailed information about the objects, such as their names and background knowledge.

[0056] Exemplarily, the first threshold wavelength range and the second threshold wavelength range may be preset to adjust the reflective sub-mirror. For example, the reflective sub-mirror may be adjusted to allow infrared light to pass through and to reflect visible light.

[0057] A concave reflective primary mirror, used to reflect light onto a reflective secondary mirror;

[0058] a lighting mechanism for collecting light passing through the reflective secondary mirror;

[0059] Exemplarily, the lighting mechanism at this time includes but is not limited to: an infrared camera.

[0060] A processor, configured to receive and process images acquired by the lighting mechanism and output the processed images;

[0061] Exemplarily, the processor has an external interface capable of receiving information from external output, the information including but not limited to: image data, telescope positioning data and encoder data.

[0062] A projection mechanism, configured to receive an image output by the processor and project the image onto the reflective secondary mirror;

[0069] Optionally, the projection mechanism includes: a micro display and a projection objective lens;

[0070] The projection objective lens is used to project the image in the micro display onto the reflective secondary mirror, so that the reflective secondary mirror reflects the image onto the imaging focal plane of the concave reflective primary mirror.

[0071] Optionally, the projection mechanism further includes a focusing device;

[0072] The focusing device is used to make the projection image of the micro display and the image of the concave reflection primary mirror coincide in the direction of the optical axis through focusing.

[0076] Illustratively, the operating principle of the image-enhanced reflecting telescope in this embodiment is as follows: the reflecting sub-mirror is arranged in the middle of the lens barrel, the lens barrel receives natural light and converges it to the reflecting sub-mirror, and the reflecting sub-mirror transfers the light to the eyepiece. The reflecting sub-mirror in the lens barrel can transmit infrared light and reflect visible light. The lighting mechanism obtains the infrared image and transmits it to the projection mechanism, which projects it onto the reflecting sub-mirror. In this way, the light reflected by the reflecting sub-mirror can be superimposed, so that the image observed by the eyepiece is two superimposed enhanced images.

[0077] Optionally, by adjusting the reflective sub-mirror, a portion of visible light can be allowed to pass through the translucent reflective lens. Then, after the projection mechanism receives the infrared image obtained by the lighting mechanism, when the reflective sub-mirror is projected and the wavelength of the light is adjusted, the visible light of the wavelength that is passed by the reflective sub-mirror is avoided. This makes it easier to align the infrared image and the visible light image, and to form an enhanced image.

The present invention can enhance telescopic images, achieving augmented reality and mixed reality telescopic effects, without incurring additional incident light loss, resulting in clearer images observed by the telescope.

[0079] The above description is merely a preferred embodiment of the present invention and an illustration of the technical principles employed. Those skilled in the art should understand that the scope of the invention is not limited to the technical solutions formed by the specific combination of the above-mentioned technical features, but also encompasses other technical solutions formed by any combination of the above-mentioned technical features or their equivalents without departing from the inventive concept.
