This paper presents an optical system for performing excitation resolved imaging of fluorescent dyes, tissue phantoms and ex vivo tissues. The excitation source was a supercontinuum generated in a highly nonlinear fibre, spectrally filtered using dispersive optics and a movable slit or digital micromirror device. This allowed excitation with multiple spectra, which may be chosen to optimize the...

The maskless lithography technology requires the management and transmission of exposure data at very high data rates. To meet these requirements, there were techniques on lossless data compression and on high performance data transmission. Many applications using Digital Micro-mirror Device (DMD) require huge and reliable data transmission and high performance processing capabilities enough to...

High resolution 3D images are of high interest in military operations, where data can be used to classify and identify targets. The Swedish defence research agency (FOI) is interested in the latest research and technologies in this area. A drawback with normal 3D-laser systems are the lack of high resolution for long range measurements. One technique for high long range resolution laser radar i...

We report on the development of a digital-micromirror-device (DMD)-based multishot snapshot spectral imaging (DMD-SSI) system as an alternative to current piezostage-based multishot coded aperture snapshot spectral imager (CASSI) systems. In this system, a DMD is used to implement compressive sensing (CS) measurement patterns for reconstructing the spatial/spectral information of an imaging sce...

Recent advances in our understanding of brain function have come from using light to either control or image neuronal activity. Here we describe an approach that combines both techniques: a micromirror array is used to photostimulate populations of presynaptic neurons expressing channelrhodopsin-2, while a red-shifted voltage-sensitive dye allows optical detection of resulting postsynaptic acti...

We demonstrate experimentally and theoretically that a coherent image of a pure phase object [implemented by a microelectromechanical system (MEMS) micromirror array] may be obtained by use of a spatially incoherent illumination beam. This is accomplished by employing a two-beam source of entangled photons generated by spontaneous parametric down-conversion. One of the beams probes the phase ob...

Using the fast measurement of a binary transmission matrix and a digital micromirror device, we demonstrate high-speed interferometric focusing through highly dynamic scattering media with binary intensity modulation. The scanning of speckles for reference optimization gives stable focusing, which can be used for focusing through a fast changing media or two dimensional scanning through a slowl...
