Imaging quality is a key factor to evaluate the quality of infrared image detector

which can direct the sensor design through direct observation of imaging effect.The goal of this research is to design a kind of imaging evaluation experimental system through which the imaging quality of IR image detector can be evaluated directly.It is a PC—DAQ virtual instrument system based on LabVIEW

the system is composed of hardware and software.The hardware platform is made up of imaging detector

external driving circuit

PCI—6115 data acquisition card and PC.The software part is made up of acquisition card control

image transformation

enhancement and display.The feasibility of system is validated through imaging experiments

it can acquire output signal of image detector and transform and process to visible light image

through which developers can observe real imaging effect

and this can provide important reference value for device modification and design.
