“…Specially designed spectral filter masks for pixles of the detector arrays are pasted using a special glue with high alignment accuracy which leads to negligible cross talk between pixels and improved Nyquist frequency. Experimental demonstration of such systems was reported by Karni et al [59]. Thee improvements may however be at the cost of marginal loss in quantum efficiency due to less than 100% fill factor.…”

Infrared thermal imaging, using cooled and uncooled detectors, is continuously gaining attention because of its wide military and civilian applications. Futuristic requirements of high temperature operation, multispectral imaging, lower cost, higher resolution (using pixels) etc. are driving continuous developments in the field. Although there are good reviews in the literature by Rogalski [1-4], Martyniuk et al. [5] and Rogalski et al. [6] on various types of infrared detectors and technologies, this paper focuses on some of the important recent trends and diverse applications in this field and discusses some important fundamentals of these detectors.

“…By reducing the image sampling resolution to 11-bit resolution, the image mode frame rate can reach up to 1600 FPS. The high frame rate mode is of highly desired in both defense and commercial related applications such as hostile fire detection, semiconductor inspection, sorting, multispectral imaging [11].…”

Event-based imagers are an emerging class of sensors with demonstrated advantages relative to traditional imagers. Event-based vision sensors have a limited number of output bits that are only responsive to image variations, thus overcoming the speed and power constraints of the conventional imagers based on image integration. The SWIFT EI the first event-based InGaAs sensor that is sensitive in the Visible to SWIR band (600–1700nm). The main novelty of this sensor is that the event channel outputs in parallel to a conventional fast imaging channel. Moreover, we can reconfigure the event channel to provide a fast laser pulse detection mode (3rd generation ALPD), which also outputs in parallel to the integrated image. In that context we described in detail the architecture, key features, and preliminary simulations of the ROIC. The SWIFT EI is a low SWaP product optimized for tactical wide distribution applications that incorporates the event based FPA. We will present measurement results of the high frame rate (HFR) imaging channel; the event channel that can reach up to 25 kHz of negative, null, or positive signal, and the laser detection channel providing a single bit detection frame up to 50 kHz. This feature is ideal for multi spot tracking and pulse repetition frequency (PRF).
