Title: Calibrating multiple microscopes with a smartphone
Published: April 01, 2014
Abstract: Summary: The iPhone liquid crystal displays allows efficient and accurate calibration of an inexpensive array of handheld microscopes for measuring microscopic dynamic events over a large field of view. How does one build an inexpensive array of handheld microscopes for measuring microscopic dynamic events over a large field of view? The challenges of building such an instrument lie in estimating spatial, temporal, and color properties of each handheld microscope, as well as in integrating individual fields of views into a large field of view seamlessly. These calibration challenges of building inexpensive arrays of cameras have been encountered and researched in close-range photogrammetry and multi-camera computer vision applications [1], [2], [3]. While the main objective of past work has been to reconstruct 3D scenes, our ultimate objective is to image live cells in an entire culture dish. A dish 10 cm in diameter cannot be imaged at the rate of cell state dynamics with a combination of a single camera microscope and a motorized stage.
