Overview
IEC 60747-18-4:2023 is an international standard published by the International Electrotechnical Commission (IEC). This standard specifically addresses the evaluation method for noise characteristics in lens-free CMOS photonic array sensors, which are widely used as semiconductor bio sensors. The document outlines a comprehensive methodology covering measurement setup, test procedures, key test items, evaluation methods, and the structure of the necessary test report. Ensuring the accurate evaluation of noise in these advanced imaging sensors supports the development, testing, and quality assurance of sensitive semiconductor devices used in bio sensing and imaging applications.
Key Topics
- Noise Characteristics: Defines types and sources of noise in CMOS photonic array sensors, including spatial noise (such as Dark Fixed Pattern Noise - DFPN and Photo Response Non-Uniformity - PRNU) and temporal noise (Random Read Noise - RRN).
- Measurement Setup: Specifies the parameters to be controlled during measurement, such as light power, illumination uniformity, environmental conditions (temperature, humidity), and electric inputs.
- Test Procedures: Details step-by-step workflows to assess various noise components, including capturing multiple frames, statistical averaging, offset removal, and calculations for noise quantification.
- Evaluation Methods: Establishes methods for the statistical processing of measurement data to ensure reliable and repeatable noise assessment results.
- Test Reporting: Requirements for documentation, covering all influencing factors, sensor specifications, and thorough presentation of evaluation results.
