This report presents the design and development of micro-optical components for a computational imaging spectrometer. The main elements that were involved in the optical design include a microlens array that samples the spatial information and a diffraction grating that provides spectral information. One of the significant drawbacks of scanning based imaging systems is the low light collection efficiency. The new technique proposed in this study used a quasi-snapshot technology that significantly improves the optical throughput. In a quasi-snapshot system, multiple images are captured with the optical system that can tune its optical transfer function (OTF). In this work, tunable micro-optics were investigated for the realization preparation of presentations, articles, and thesis; Python package distribution especially numpy, mathplotlib; Mendeley for reference managing; Inkscape for vector graphics editor; KLayout for mask designing; and Fiji-ImageJ for image processing and analysis. I would also like to thank all others, whose direct or indirect help has benefited me during my stay at Nanyang Technological University. I express my gratitude towards all those unseen and unknown people associated with the internet, and the plethora of technical websites, forums, groups and mailing lists which have helped me with study material for my research work. Last but not the least, I would like to thank my parents and family members for their eternal love and extensive support all throughout my career.
