SBIR Phase I: Two-Wavelength Thermal Imaging Solutions to Materials Process Control Needs

9860678这个小型企业创新研究第一阶段项目将研究一种双波长成像高温计，使用基于硫化铟镓(InGaS)的相机来监控高温材料过程。创新的双波长成像使用强度比来提供具有发射率变化的物体的准确温度测量。单波长成像传感器将发射率变化引起的绝对强度变化误认为温度变化。在许多形式的高温材料加工中，温度是核心参数。对长时间生产运行的温度控制提供了产品的一致性和一致性，同时降低了制造成本。第一阶段将设计和建造一个带有InGaS相机的双波长成像高温计原型，并在选定的工业和研究机构的材料加工设施中进行实验室评估和测试。这种热成像传感器有望满足工业对精度、高温运行和低成本的需求。开发的热成像传感器具有1-2微米的灵敏度，将广泛应用于高温材料加工过程控制传感器的工业需求。

9860678 This Small Business Innovation Research (SBIR) Phase I project will investigate a two-wavelength imaging pyrometer, using an indium gallium sulfide (InGaS)-based camera, to monitor high-temperature materials processes. The innovative two-wavelength imaging uses intensity ratios to provide accurate temperature measurement of objects with emissivity variation. Single wavelength imaging sensors mistake absolute intensity changes, caused by emissivity variation, for temperature changes. Temperature is a central parameter in many forms of high-temperature materials processing. Temperature control over long production runs provides product consistency and uniformity at reduced manufacturing costs. Phase I will design and construct a prototype two-wavelength, imaging pyrometer with InGaS camera and perform laboratory evaluations and tests in materials processing facilities of selected industrial and research organizations. This thermal imaging sensor is expected to meet industrial needs for accuracy, high temperature operation, and low cost. The developed thermal imaging sensor, with its 1-2 micron sensitivity, will find wide application to industrial needs for process control sensors for high temperature materials processing.
