“…If the Si based image sensor can account for the requirement with cost effective processes, it is advantageous to combine the wide spectral sensitivity performance with other high performance imaging technologies such as low noise, wide dynamic range and high frame rate technologies. In addition, application fields of UV/VIS/NIR imaging would be applied to consumer usage such as mobile spectroscope, hyperspectral imaging [5], health condition monitoring and so on.…”

Challenges and opportunities of ultraviolet (UV), visible (VIS) and near-infrared (NIR) light imaging technologies are overviewed in this paper. For light detectors and image sensors for UV/VIS/NIR imaging, it is required that they have high sensitivity for wide spectral light waveband or targeted narrow waveband as well as the high stability of light sensitivity toward UV light based on cost effective technology. Wide spectral response, high sensitivity and high stability advanced Si photodiode (PD) pn junction formation technology based on the flattened Si surface and high transmittance on-chip optical filter formation technology were developed. A linear photodiode array (PDA), wide dynamic range and ultrahigh speed CMOS image sensors employing the developed technology were fabricated and their advanced performances are described in this paper.

Despite the broad application of the handheld thermal imaging cameras in firefighting, its usage is mostly limited to subjective interpretation by the person carrying the device. As remedies to overcome this limitation, object localization and classification mechanisms could assist the fireground understanding and help with the automated localization, characterization and spatio-temporal (spreading) analysis of the fire. An automated understanding of thermal images can enrich the conventional knowledge-based firefighting techniques by providing the information from the data and sensing-driven approaches. In this work, transfer learning is applied on multilabeling convolutional neural network architectures for object localization and recognition in monocular visual, infrared and multispectral dynamic images. Furthermore, the possibility of analyzing fire scene images is studied and their current limitations are discussed. Finally, the understanding of the room configuration (i.e., objects location) for indoor localization in reduced visibility environments and the linking with Building Information Models (BIM) are investigated.

“…Also dedicated imager post-processing of e.g. Fresnel type micro-lenses [4] and hyperspectral filters (both at pixel level) [5] are available. Contrary to commercial foundries, imec is flexible in adapting the process flow in order to meet high-end imager customer requirements.…”
