“…Infrared radiation measurements are conducted using a FLIR SC7600 mid-wave IR camera with an InSb detector. The focal plane array consists of an SCD Pelican sensor [24], connected to a 14-bit A/D. Optics include the FLIR ATS L0118 lens, and a narrow bandpass filter with central wavelength of 3.46 µm situated inside the camera's internal filter wheel.…”

“…The ensuing unbiased object image fits the model in equation 23, and when repeated for several IT settings, results in a set that can be fused using equation (18). This 'augmented NUC' (ANUC) data fusion has the implicit assumption of constant P in equation (24) and cannot be used to gather independent photoquantity information for the dark frame and the scene image, as required for equation (21). The acquisition techniques that produce fusible data are summarized as…”

Towards high-accuracy infrared radiance estimates, measurement practices and processing techniques aimed to achieve quantitative image fusion using a set of multi-exposure images of a static scene are reviewed. The conventional non-uniformity correction technique is extended, as the original is incompatible with quantitative fusion. Recognizing the inherent limitations of even the extended non-uniformity correction, an alternative measurement methodology, which relies on estimates of the detector bias using self-calibration, is developed. Combining data from multi-exposure images, two novel image fusion techniques that ultimately provide high tonal fidelity of a photoquantity are considered: 'subtract-then-fuse', which conducts image subtraction in the camera output domain and partially negates the bias frame contribution common to both the dark and scene frames; and 'fuse-then-subtract', which reconstructs the bias frame explicitly and conducts image fusion independently for the dark and the scene frames, followed by subtraction in the photoquantity domain. The performances of the different techniques are evaluated for various synthetic and experimental data, identifying the factors contributing to potential degradation of the image quality. The findings reflect the superiority of the 'fuse-then-subtract' approach, conducting image fusion via per-pixel nonlinear weighted least squares optimization.

Modern electro-optical systems contain several components such as thermal imager, laser designator, laser range finder, etc. The dem and for com pact syste ms w ith l ow po wer co nsumption an d l ow cost can be ad dressed by i ncorporating some of the traditional system abilities into the IR detector. We present SNIR, a new type of detector, which consists of a Read O ut Int egrated C ircuit (R OIC) wi th adva nced o n-chip si gnal p rocessing. T he R OIC i s fl ip chi p-bonded to a 640×512 In Sb det ector ar ray of 1 5µm pi tch. S NIR di gital R OIC can b e ope rated i n either o ne of t he f ollowing f our different modes of operation. The first operation mode is standard thermal imaging, which has typical functionalities and performance of MWIR detector. The second operation mode is a dual-function mode that includes both standard thermal imaging and information on Asynchronous Laser Pulse Detection (ALPD) for each pixel. The detection probability of a laser pu lse is significantly in creased by i ntegrating a dedicated i n-pixel circu it fo r iden tifying a fast sig nal tem poral profile. Since each pixel has internal processing to ide ntify laser pulses, it is possible a lso to m easure the ela psed time between a trigg er and th e detection of a laser pulse. Th is yi elds a t hird m ode of operation i n which the detector i s synchronized t o a l aser an d becomes a Tw o-dimensional Laser R ange Finder (TLRF). T he forth operation m ode i s dedicated to Low Noise Imaging (LNIM) for the SWIR band, where the IR radiation signal is low. It can be used in both passive or active imaging. We review some of t he predicted and measured results for the different modes of operation, both at the detector level and at the system level.

“…The IRFPA of western developed countries is evolving toward broad specifications, many spectral bands, and digitisation. In order to greatly enhance the total IRFPA performance of infrared thermal imagers, reachers in Israel, France, and Turkey have introduced useful goods for digital infrared focal plane array detector components in specifications like 640×512, 1280×1024, and 1920×1536 [9][10][11]. Particularly, the SWaP (Size, Weight, and Power) has been proposed for the digital infrared focal plane array detector components [12][13][14][15].…”
