Abstract: In one embodiment, an imaging method may include receiving an intensity value of a first spectral channel associated with a pixel location. The intensity value of the first spectral channel may be based on electromagnetic radiation reflected from an object after being emitted from a narrow-band electromagnetic radiation source. The method may further include defining an intensity value of a second spectral channel based on the intensity value of the first spectral channel. The second spectral channel may be associated with a spectral region of electromagnetic radiation different from a spectral region of electromagnetic radiation associated with the first spectral channel. The method may also include associating the intensity value of the second spectral channel with the pixel location.

Abstract: A device (1) for analysing the material composition of an object (2) has a casing (3) with a handle (4), an operating trigger (5), a window (6) for abutment against the object to be analysed and a display (7) for displaying the analysis of the object. Mounted in the casing is a housing (11) having a base (12) to which it is pivotally connected about an axis (14) at one end (15). At the other end (16), a stepper motor (17) is provided for traversing the end across the base. This end has an opening (18) generally in alignment with an opening (19) in the housing in which the window is mounted. Within the housing, are mounted: a laser diode (21); a laser amplification crystal (22); a collimating lens (23); a laser focusing lens (24). The components are arranged on a laser projection axis (25), which passes out through the openings (18,19). A plane mirror (32) can receive light emitted by a plasma P excited at the surface of the object (2). Light from the plasma P is reflected in the direction (34) across the projection axis to a curved focusing mirror (35). From this mirror, the light is reflected again across the projection axis and focused on the end of an optical (fibre (37) set in an aperture (38) in the side wall (39) of the housing opposite from the reflecting mirror.

Abstract: A hydrogen sensor for detecting/quantitating hydrogen and hydrogen isotopes includes a sampling line and a microplasma generator that excites hydrogen from a gas sample and produces light emission from excited hydrogen. A power supply provides power to the microplasma generator, and a spectrometer generates an emission spectrum from the light emission. A programmable computer is adapted for determining whether or not the gas sample includes hydrogen, and for quantitating the amount of hydrogen and/or hydrogen isotopes are present in the gas sample.

Abstract: An image pickup apparatus has a construction in which a diffraction element is provided in an observation optical system. Zero-order light that is transmitted straight through the diffraction element and one of the +1st-order diffracted light and the −1st-order diffracted light that is diffracted by the diffraction element are imaged onto an image pickup surface of an image pickup apparatus. The imaging areas of the zero-order light and one of the +1st-order diffracted light and the −1st-order diffracted light that is diffracted by the diffraction element do not overlap on the image pickup surface of the image pickup apparatus. With this construction, a small image pickup apparatus that provides a high-resolution spectral image and a color image of an object can be obtained.
