Low cost 3D Scanner at Home

In the field of imaging there is another branch of image acquisition/analysis/study that is called Computational Photography as distinguished from traditional photography. In traditional photography, with a regular camera, you take a picture of a 3D scene through a camera. This light from the scene is captured as a 2-dimensional representation onto a photo-sensitive surface,…

Cell change shape frequently as they move and divide but the measurement of the thickness is difficult. Current microscopy techniques can measure the dimensions in X and Y axis very accurately but cannot measure the cell thickness. Confocal microscopy, that is usually used with fluorescence dyes can measure the thickness of the cell but it…

Luminescent phosphors have been used in biology and imaging for many applications. Interestingly, there is another application that has not been publicized as much. Scientists from Malaysia, Moldova and Russia have made unique persistent phosphors that last for many days and hours in tough environment below the ocean. These are originally made nearly 16 years…
