Optical sensing techniques: IR sensors, passive IR sensors, photo-resistive sensors, photovoltaic sensors, photodiodes, photoelectric detectors, solid state lasers.
Signal processing techniques: theories and applications of auto-correlation and cross-correlation.

IMAGING BASED MEASUREMENT AND MONITORING TECHNIQUES

Digital imaging technologies: architectures of CCD and CMOS (structure of sensor array, charge generation, collection and transfer, frame readout, digitisation), characteristics of CCD and CMOS (resolution, gain, dynamic range, spectral response, linearity, noise and sensitivity), colour generation, CCD vs CMOS, camera interfaces, special cameras.

Image processing techniques: Image array, image enhancement and filtering, histogram modification, edge detection and segmentation, feature extraction, Fourier domain representations and filtering.

Imaging systems: CCD/CMOS camera based measurement and detection systems, (passive imaging, laser-based systems), industrial process tomography (IPT), stereoscopic imaging systems, case study.

INTELLIGENT MEASUREMENT AND MONITORING TECHNIQUES
