Design and Realization of a Lensless CMOS Image Sensor for Light Source Tracking

Localization of a light source in the space requires capturing its light intensity and angle information. However, conventional CMOS image sensors can only capture light intensity and wavelength. These sensors need to be augmented with an optical extension such as an aperture or a lens in order to capture the angle information. The use of...

A probabilistic physics-of-failure reliability assessment approach for integrated LED lamps

This work studies the effect of randomness of LED's lumen depreciation on reliability of the entire LED lamp. An integrated LED light bulb is selected as carrier of the proposed method. A PoF based lumen depreciation model and electronic-thermal simulations are introduced for reliability prediction. The normal distribution is used to describe...

Micromachined lamps for tissue spectroscopy

An implant designed to treat glioblastoma multiforme, GBM, in the brain which makes use of metronomic Photodynamic Therapy (mPDT) is being developed. A device to do spectrography is needed in this implant to monitor the evolution of the treatment. Therefore, the aim of this research is to study the viability of a micromachined lamp to do...
