基于比色測溫原理設(shè)計(jì)的測溫系統(tǒng)能夠提高其抗干擾性能。本文首先分析雙波段
比色測溫原理，然后將其應(yīng)用到一種基于面陣CCD 的測溫?cái)z像機(jī)的設(shè)計(jì)中。這個(gè)攝像機(jī)系統(tǒng)通過USB2.0 接口與PC 主機(jī)相連，可以達(dá)到實(shí)時(shí)監(jiān)控被觀測環(huán)境及目標(biāo)物溫度的目的。使用的面陣CCD 在近紅外波段有頻譜響應(yīng)，可以采集到足夠的光能量。這種CCD 比專業(yè)紅外探測器件價(jià)格低廉，應(yīng)用它制作的系統(tǒng)降低成本。因此本文提出的基于近紅外增強(qiáng)CCD 設(shè)計(jì)的測溫?cái)z像機(jī)系統(tǒng)是一種具有強(qiáng)抗干擾能力和低成本兩方面優(yōu)勢的設(shè)備。

Abstract Colorimetric temperature measurement can bring better anti-jamming. In this paper,
it discussed the colorimetric temperature measurement firstly. Then it proposed a video acquisition system using planar CCD. This system can transfer signals to PC by USB2.0 interface. So customers may inspect environmental temperatures on time. Cheep CCD collects enough light energy to transfer. Since its lower price and better anti-jamming ability, this system has obvious advantages.
