Application: High Speed Near Infrared (NIR) and Short Wave Infrared (SWIR) Imaging for High Speed Transient Events
Vehicle impact testing, ballistic motion analysis, and missile tracking are a few of the applications that require cameras capable of high frame rates and short exposure times. Goodrich produces a 640 x 512 pixel InGaAs camera capable of 109 full frames per second (fps) with frame rates over 15,220 fps depending on the selected pixel area. The camera's windowing capabilities enable the acquisition of user definable regions of interest for target tracking and ballistic analysis in the wavelength range of 0.9 to 1.7 um.
Short exposure times create a snapshot image of transient events allowing the user to examine a phenomenon in incremental steps of time. Water absorption bands in the shortwave infrared (SWIR) make the InGaAs camera ideal for imaging and measuring a material's water content as it dries. The temperature uniformity of rapidly cooling glass materials in the manufacturing process can be monitored with InGaAs cameras, as well. The thermal response for materials over 100ºC plus the ability to see through glass makes the Goodrich InGaAs camera a superior detector over visible and thermal detectors.
