Abstract: A trolley 2 for use in recyclable waste collection in an aircraft or other catering environment is conformal with a normal aircraft trolley. The trolley 2 comprises a horizontal tray 14 18 19 20 21 comprising a plurality of horizontal apertures, each aperture comprising a rubbish bag 19 20 held therein by its edges 22 between a tray base 14 and tray cover 18 that snap together. Before use the rubbish bags 19 20 are contained within the horizontal tray 14 18 19 20 and are freed to hang vertically within the trolley 2 when in use. The trolley 2 comprises a retractable lid which covers the tray assembly 14 18 19 20 21 when the trolley 2 is not in use. A liquid waste container 21 also fits into the tray and is independently removable for emptying without removing rubbish bags 19 20. The apertures and/or the rubbish bags 19 20 are colour coded according to the type of waste they are intended to receive and according to the colour coding employed in the country where recycling is intended to occur.

Abstract: A device to illuminate a object, to excite its fluorescence light emission, and detect the emitted fluorescence spectrum, comprising: at least one illumination system (13), adapted to receive light from a light source (11), to select at least one wavelength bands of light spectrum of the source (11), to illuminate a object (15) with light filtered in that way (14); and a detection system (17), adapted to detect fluorescence light (16) emitted by the object (15), to select at least one wavelength bands of fluorescence, light spectrum (16), to record the spectrum of the filtered light; characterized in that said illumination system (13) comprises: at least one first dispersive element (41), at least one focusing optics (43), at least one spatial fitter of excitation (44), at least one collimating optics (45) and at least one second dispersive element (47), wherein said detection system (17) comprises: at least one dispersive element (81), at least one focusing optics (83), at least one spatial filter of detecti

Abstract: Apparatus for real-time three-dimensional laser scanning microscopy, where single-photon fluorescence light, multi-photon fluorescence light, and higher order harmonics generated in the sample are detected. The excitation light is focused into the sample in a three-dimensional matrix of focal points. Real-time three-dimensional image acquisition is obtained by fast scanning in the xy plane only.
