Abstract: An apparatus for placement on or in a body of water for hyperspectral imaging of material in the water comprises an artificial light source and a hyperspectral imager. These are arranged so that in use light exits the apparatus beneath the surface of the water and is reflected by said material before re-entering the apparatus beneath the surface of the water and entering the hyperspectral imager. The hyperspectral imager is adapted to produce hyperspectral image data having at least two spatial dimensions.

Abstract: A system and method of high-speed microscopy using a two-photon microscope with spectral resolution. The microscope is operable to provide spectrally resolved, multi-dimensional images from a single scan of a sample. The microscope may include one of a multi-beam point scanning microscope, a single beam line scanning microscope, and a multi-beam line scanning microscope. The microscope includes a descanning arrangement such that emitted fluorescence is static on a receiving detector. The detector is a narrow detector with a width at least half the size of the length, to reduce the amount of pixel data being transmitted and improve scan speeds. The microscope may also incorporate one or more binning techniques whereby pixels are binned together to improve resolution or scan speeds.

Abstract: An optical spectrum analyzer is implemented with a detector combined with a tunable filter mounted on a stage capable of 360-degree rotation at a constant velocity. Because of the constant rate of angular change, different portions of the input spectrum are detected at each increment of time as a function of filter position, which can be easily measured with an encoder for synchronization purposes. The unidirectional motion of the mirror permits operation at very high speeds with great mechanical reliability. The same improvements may be obtained using a diffraction grating or a prism, in which case the detector or an intervening mirror may be rotated instead of the grating or prism.
