Low Light Imaging

While traditional remote sensing instruments acquire imagery under bright illumination conditions, focal plane technology is advancing and enabling low light level image acquisition. Images acquired at sunrise and sunset, twilight and at night under artificial illumination require new techniques to calibrate and extract useful information from. These types of images support disaster response, activity monitoring and power consumption estimations.

I2R is advancing night imaging by providing:

• In-flight night-time absolute radiometric calibration using Terra Vega, the I2R-developed portable automated NIST-traceable active calibration light source

• Radiometric camera calibrations at low light level

• Image enhancement and information extraction algorithms
