GB/T 43971-2024 in English

1. Standard Overview

GB/T 43971-2024 "Test Specification for Integrating Sphere Light Source for Remote Sensor Calibration" is under the jurisdiction of the National Technical Committee for Standardization of Remote Sensing Technology (SAC/TC 327). It is applicable to the test of integrating sphere light sources with an output wavelength range from ultraviolet to short-wave infrared ($350\mathrm{nm} \sim 2500\mathrm{nm}$) and a light outlet diameter greater than or equal to $100~\mathrm{mm}$.

2. Background of Standard Formulation

With the rapid development of remote sensing technology, higher requirements are placed on the accuracy and reliability of remote sensor calibration. This standard aims to standardize the test method of integrating sphere light sources to ensure that their performance in remote sensor radiation calibration meets the standards.
