    Abstract: A microscopy imaging system is disclosed that includes a light source system, a spectral shaper, a modulator system, an optics system, an optical detector and a processor. The light source system is for providing a first train of pulses and a second train of pulses. The spectral shaper is for spectrally modifying an optical property of at least some frequency components of the broadband range of frequency components such that the broadband range of frequency components is shaped producing a shaped first train of pulses to specifically probe a spectral feature of interest from a sample, and to reduce information from features that are not of interest from the sample. The modulator system is for modulating a property of at least one of the shaped first train of pulses and the second train of pulses at a modulation frequency. The optical detector is for detecting an integrated intensity of substantially all optical frequency components of a train of pulses of interest transmitted or reflected through the common focal volume. The processor is for detecting a modulation at the modulation frequency of the integrated intensity of substantially all of the optical frequency components of the train of pulses of interest due to the non-linear interaction of the shaped first train of pulses with the second train of pulses as modulated in the common focal volume, and for providing an output signal for a pixel of an image for the microscopy imaging system.

    Abstract: A spectral imaging system for collecting spectral information of a two dimensional heterogeneous objects while in motion relative to the imaging system without the use of a spectrograph, filters or any dispersive optics. The system includes a pulsed light source tunable in wavelength for producing short pulses of wavelength tuned light at a plurality of selected narrow band wavelengths within a spectral range and one or more optical components for conveying or directing the short pulses of light to a two dimensional region that is substantially stationary with respect to the imaging system and through which the two dimensional target is moving. The system also includes a many pixel camera synchronized with the tunable pulsed light source. The camera is adapted to detect light in the selected narrow band wavelengths produced by the tunable pulsed light source and reflected from or transmitted through the two dimensional target in motion relative to the imaging system and to provide image frame information with each frame at a defined wavelength band. A processor processes information from said tunable light source and said camera and to produce multi-spectral images of the target.

    Abstract: The invention relates to a variable-spectrum solar simulator for characterising photovoltaic systems. The simulator can be used to obtain a spectrum adjusted to the solar spectrum, both for a standard spectrum or a real spectrum adjusted to local irradiation conditions. The simulator also allows the spatial-angular characteristics of the sun to be reproduced. The invention comprises: a broad-spectrum light source, the flux from which is emitted through an aperture; an optical system which collimates the primary source; a system which disperses the beam chromatically; an optical system which forms an image of the dispersed primary source at a given position, at which a spatial mask is placed in order to filter the received irradiance spectrally; an optical system which captures the filtered spectrum and returns, mixes and concentrates same in a secondary source with the desired spectral, angular, and spatial characteristics; an optical system which collimates the secondary source such that it reproduces the angular characteristics of the sun; and a control system.
