Abstract: An operating value of a first laser parameter of a laser device in a laser absorption spectrometer is optimised. The wavelength of laser device emitted light is adjusted by the first or a second laser parameter. The laser absorption spectrometer comprises a light intensity detector measuring the laser light intensity from the laser device. For each of multiple values of the first laser parameter: the light intensity detector measures light intensity obtained across a range of second laser parameter values, and an extremum in the light intensity measure and a peak position for the extremum are identified. A range of first laser parameter values is identified within the values of the first laser parameter for which there is a continuous trend in changes to the identified peak position with changes to the first laser parameter. The first laser parameter operating value is set to be within the identified range.
The laser device is either a mid-infrared LD or the difference frequency generated in a PPNL (250) using the output of two near infrared telecommunication laser diodes (210,220) having for example a DFB (220). The wavelength sweep is realized by a corresponding control of temperature and bias current provided to the LD while the absorption peaks of the isotopes to be detected should be in the middle of the individual sweep ranges.

Abstract: A modular device includes base and color sensing portions. The color sensing portion has a face, a controlled light source offset from the face to define an interior, the face configured to engage a target surface about a perimeter of the device housing wherein ambient light is restricted from entering the interior. A color sensor receives light reflected from the target surface and generates output signals representative of a surface color. The base portion communicates with the color sensor and a user device having a hosted program which generates a user interface enabling users to provide control input for the color sensor. The program further receives the output signals from the color sensing device and displays a first image of the detected color, and displays a second image of a user-selected color beside the first image. Color data values are further displayed corresponding to the difference between displayed colors.

Abstract: [Problem] A practicable quantum meter capable of knowing the photosynthetic photon flux density at each wavelength in real time is presented.
[Solution] Measurement light made incident on a dispersive element 12 by an incident optical system 13 in a spectroscope unit 1 is dispersed by the dispersive element 12, and converted to photoelectric signal on the detector 14. Each photoelectric signal at each wavelength (spectral data) is transmitted to the processing unit 2, which is a general use computer, via interface members 16 and 26. The processing unit 2, to which a photosynthetic photon flux density measurement program 4 and a special device driver 262 have been installed, calculates the distribution of the photosynthetic photon flux density at each wavelength by processing the received spectral data, and displays it on display 24.

Abstract: Provided is a gas absorption spectroscopic system and gas absorption spectroscopic method capable of accurately measuring the concentration or other properties of gas even in high-speed measurements. Laser light with a varying wavelength is cast into target gas. A spectrum profile representing a change in the intensity of the laser light transmitted through the target gas with respect to wavelength is determined. For this spectrum profile, polynomial approximation is performed at each wavelength point within a predetermined wavelength width, using an approximate polynomial. Based on the coefficients of the terms in the approximate polynomial at each point, an nth order derivative curve, where n is an integer of zero or larger, of the spectrum profile is created. A physical quantity of the target gas is determined based on the thus created nth order derivative curve.
