Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing telescopes are limited to monocular viewing and lack the functionality to measure target distance and velocity, display measured data, and adjust focal and pupillary distances, making them inconvenient for users.
Innovation Solution
A binocular telescopic optical system incorporating a composite prism with a first and second half-pentaprism, a roof prism, and a reticle lens, which allows for binocular viewing, laser distance and velocity measurement, and projection display of data via transmissive LCD or OLED, with adjustable focal and pupillary distances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional monocular telescope design is used, then the structure is simple, but the convenience for users to view and the functionality are limited
Solution Approach 1:
The patent implements a binocular telescope that integrates multiple functions including distance measurement, velocity measurement, and projection display capabilities. The system combines a binocular viewing system with laser ranging and velocimetry functions, allowing a single device to serve multiple purposes that would traditionally require separate instruments
Solution Approach 2:
The patent merges the binocular viewing system with laser ranging and velocimetry systems into a single integrated telescope. The optical path combines visible light transmission for viewing with laser beam transmission for measurement functions, consolidating multiple subsystems into one unified device
2Adaptability or versatility
If multiple functional components are added to the telescope, then the functionality improves, but the space occupation increases
Solution Approach 1:
The patent employs a composite prism structure where multiple optical functions are nested within a single integrated component. The half-pentaprism, roof prism, and light-splitting film are combined in a nested arrangement where the laser beam path is nested within the visible light optical path, allowing multiple functions to coexist in a compact volume
Solution Approach 2:
The patent utilizes the light-splitting film to create a dimensional separation of optical paths. The film splits the optical space into visible light transmission for viewing and laser beam transmission for measurement, effectively adding a functional dimension without increasing physical volume
3Adaptability or versatility
If a light-splitting film is added to the composite prism, then the laser measurement function is enabled, but the manufacturing complexity increases
Solution Approach 1:
The light-splitting film is applied only to specific surfaces of the composite prism where laser beam splitting is required, rather than coating the entire optical system. This localized application reduces the overall manufacturing complexity while enabling the laser measurement function
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system enables multifunctional binocular viewing, precise distance and velocity measurement, and direct or projected data display, while maintaining optical stability and flexibility for various telescope configurations, reducing space occupation and improving light splitting performance.
Implementation Method 1
cemented surfaces of the first half-pentaprism and the roof prism are coated with a light-splitting film which can reflect laser light and is transmissive to visible light
Implementation Method 2
cemented surfaces of the first half-pentaprism and the roof prism are coated with a light-splitting film which can reflect laser light and is transmissive to visible light
Implementation Method 3
light passes into the first half-pentaprism of the composite through the objective lens
Implementation Method 4
enters into the roof prism from the cemented surfaces of the first pentaprism and the roof prism through the reflection of an oblique surface of the first half-pentaprism
Implementation Method 5
a laser or a laser receiver is arranged on an optical path vertical to an oblique surface of the first half-pentaprism

AI summary
A composite prism for a multi-functional telescope, and binocular telescopic optical system for same. The composite prism comprises a first half-penta prism (2), a roof prism (3), and a second half-penta prism (4). Elongated right-angled surfaces of the first half-penta prism (2) and second half-penta prism (4) are adhered to a base surface of the roof prism (3). A light incoming surface of the roof prism (3) is the same as a light emitting surface thereof, and is parallel to the roof of the roof prism (3), such that an incoming light axis and an outgoing light axis of the composite prism are parallel. A binocular telescopic optical path system comprises an object lens (1), the composite prism, a reticle lens (5), and an ocular lens (6), and has functions of viewing, aiming, laser emitting and receiving, and display.
