| 摘 要： | 针对基于彩色CCD的高温场辐射测温问题,提出利用红、绿基色值进行比色测温来获取单一光圈快门组合内的最大测温范围,并进一步利用变换光圈快门组合来使得测温范围能够覆盖高温生产的常用温度范围；通过标定减少CCD光谱响应带宽和被测对象光谱发射率对测温精度的影响,提高测温精度.在此基础上,开发了CCD高温场测量仪.计量校准结果表明,测温仪具有较高的测温精度和实用性,能够满足常见高温生产过程对于温度测量的应用要求. |

| Abstract: | A novel high-temperature radiation thermometry is proposed,which uses red and green primary colors to colorimetric thermometry in order to get largest measurement range in an aperture and shutter combination.Then,the measurement range is extended to cover the temperature range commonly used in high-temperature production by changing aperture and shutter combinations.Finally,The errors arising from CCD spectrum response bandwidth and unknown emissivity of the measured object are reduced through calibration.O... |
