Solution Overview

Problem

Existing methods for determining single-photon emitters, such as the Hanbury Brown-Twiss (HBT) experiment, are time-consuming and labor-intensive, making it difficult to efficiently identify single-photon emitters from point light sources.

Innovation Solution

A method using deep learning to analyze single-photon point light source images, specifically through a trained artificial neural network model, to distinguish between single-photon and non-single-photon emitters without conducting HBT experiments.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If HBT experiment is used to measure second-order correlation function, then measurement precision is improved, but time consumption increases

Engineering Contradiction:
Improvesingle-photon emitter determination accuracyVSAvoidtime required for HBT experiment
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent replaces the mechanical/optical HBT experiment system with a computational deep learning system. Instead of performing physical correlation measurements through complex optical paths and timing electronics, the system uses trained neural network models to classify emitters based on image data, substituting a time-consuming physical measurement process with a computationally efficient classification approach

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent creates a computational model (deep learning network) that learns from training data to replicate and generalize the identification capability of HBT measurements. The model captures the essential characteristics of single-photon emitters from training examples and can quickly identify them in new data without requiring actual HBT measurements, effectively copying the measurement function through learning rather than direct measurement

Inventive Principle:
Principle #26Copying

2Measurement precision

If HBT experiment is performed to determine single-photon emitter, then measurement precision is improved, but labor intensity increases

Engineering Contradiction:

Core Design Contradiction:

Solution Approach 1:

The patent replaces manual or semi-manual HBT experiment operations with an automated deep learning classification system. The system automatically processes images, extracts features, and classifies emitters without requiring skilled operators to perform complex correlation measurements, thereby reducing labor intensity while maintaining determination accuracy

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The deep learning system performs self-service by automatically learning from training data and independently classifying new emitter data without requiring human intervention in the measurement or analysis process. The model autonomously identifies single-photon emitters based on patterns learned during training, eliminating the need for manual operation of HBT experiments

Inventive Principle:
Principle #25Self-service

AI summary

A method for determining a single-photon emitter based on deep learning, performed by at least one electronic device, may include: acquiring input data based on a single-photon point light source image; generating determination information expected values by inputting the input data to a trained artificial neural network model; and determining whether an emitter providing the single-photon point light source image is a single-photon emitter or a non-single-photon emitter, based on the determination information expected values.
