External Camera Schmidt Telescope for Reduced Exposure Blur
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Classical Schmidt telescopes face challenges in image capture due to long exposure times and limited access to imaging components, which can result in blurring or motion effects, and require specialized equipment for focusing light on curved surfaces.
Innovation Solution
A telescope system design that positions the camera body outside the housing, allowing for user-adjustable orientation and easy access, featuring a primary mirror, Schmidt corrector plate, and a lens group that focuses light at a focal location outside the housing, enabling the use of various digital imaging systems and facilitating image capture with reduced distortion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the camera body is positioned inside the telescope housing, then the optical path is compact, but the access to imaging components is limited and adjustments are difficult
Solution Approach 1:
The camera body is extracted from the interior of the telescope housing and positioned externally. This allows users to easily access the camera for adjustments, battery changes, and image retrieval without disassembling the telescope housing, while the optical path remains intact through the housing's aperture.
2Measurement precision
If long exposure times are used for photographing celestial bodies, then image detail is improved, but motion effects and blurring increase
Solution Approach 1:
The telescope housing is designed with adjustable orientation capabilities, allowing the user to dynamically adjust the telescope's angle and position during exposure. This enables tracking of celestial bodies to compensate for Earth's rotation, maintaining image clarity while using longer exposure times for detailed imaging.
3Ease of operation
If the focal location is inside the housing, then the optical path is shorter, but the camera body cannot be easily accessed or adjusted
Solution Approach 1:
The camera body is positioned in a different spatial dimension relative to the housing - externally rather than internally. The optical path extends from the primary mirror through the housing aperture to the external camera body, utilizing the external space to achieve both a functional optical path and easy camera accessibility.
4Ease of manufacture
If a spherical primary mirror is used, then manufacturing is simplified, but spherical aberration occurs without correction
Solution Approach 1:
A Schmidt corrector plate is introduced as an intermediary optical element positioned in front of the spherical primary mirror. This corrector plate compensates for spherical aberration by pre-correcting the incoming light waves, allowing the use of a simple spherical mirror while achieving high image quality.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design enhances image capture capabilities by allowing for quick adjustments and reduced exposure times, improving image clarity and accessibility, while accommodating different camera systems and wavelengths of light.
Implementation Method 1
The Schmidt corrector plate may be positioned proximate the entrance aperture to direct the light toward the primary mirror in a manner that substantially compensates for the spherical shape
Implementation Method 2
The primary mirror may be positioned proximate the mirror end, and may have a spherical shape
Implementation Method 3
The lens group may focus the light at a focal location further than the Schmidt corrector plate from the primary mirror
Implementation Method 4
The lens group may focus the light at a focal location further than the Schmidt corrector plate from the primary mirror

AI summary
A telescope system may facilitate the capture of images of light, and may have a housing, a primary mirror, a Schmidt corrector plate, and a lens group. The housing may have a mirror end and an aperture end with an entrance aperture that receives the light. The primary mirror may be positioned proximate the mirror end, and may have a spherical shape. The Schmidt corrector plate may be positioned proximate the entrance aperture to direct the light toward the primary mirror in a manner that substantially compensates for the spherical shape. The lens group may include multiple lenses, one or more of which may be positioned within the housing proximate the aperture end such that the light is directed through the lens group by the primary mirror. The lens group may focus the light at a focal location further than the Schmidt corrector plate from the primary mirror.
