{ "item_title" : "An Infrared Camera Simulation for Estimating Spatial Temperature Profiles and Signal-to-Noise Ratios of an Airborne Laser-Illuminated Target", "item_author" : [" David F. Orth "], "item_description" : "Airborne Laser testing and evaluation can be aided by developing a spectrally-based infrared camera simulation to explore how the target surface's specular and diffuse reflectivities affect the observed signal-to-noise ratio (SNR)and how the target's temperature in the laserspot can estimated. This simulation provides for the observed irradiance, scaled by atmospheric absorption, to consist of the target's self-emission, reflected background emission, and the path emission from the observer to the target. The observed irradiance isscaled and distributed onto a focal plane array by way of a simulated optical system, whose effectsare described by modulation transfer functions. The modeled detector response converts the observed irradiance to a current signal from which detector noise quantities are computed. Analyzing the simulated data shows that the observed SNR is dependent upon the target's reflectivity, and leads to a conclusion that the mid-wave infrared band is best choice for observing the thermal emission. For estimating temperature, a least-squares optimization will not work because of the effects of the point spread function.", "item_img_path" : "https://covers3.booksamillion.com/covers/bam/1/28/833/243/1288332432_b.jpg", "price_data" : { "retail_price" : "57.95", "online_price" : "57.95", "our_price" : "57.95", "club_price" : "57.95", "savings_pct" : "0", "savings_amt" : "0.00", "club_savings_pct" : "0", "club_savings_amt" : "0.00", "discount_pct" : "10", "store_price" : "" } }
