Abstract: An interference filter transmission wavelength scanning photometer wherein the angle of inclination of an interference filter (3) is periodically varied, the wavelength of the light to be transmitted is modulated with the periodical variation centered at the maximum absorption wavelength of the interesting component, the variation of the intensity of the light transmitted through a sample is extracted by an infrared sensor (11) as an electrical signal. The time between the rise and fall zero cross points of the AC component of the electric signal is determined by a microprocessor (16), the ratio (Tnull2T1)/T. is calculated from the full period T (time for every other zero cross point of the AC component) and half period T1 (the time for every zero cross point of the AC component) obtained from the above determined time, and the concentration of the interesting component is determined from the variation of the result of the calculation of the ratio, thereby quantitatively determining the component without interfering of the coexistent components.

Abstract: Light under measurement whose wavelength is continuously swept is incident on fiber-optic Etalon. The fiber-optic Etalon transmits the light under measurement each time the wavelength of the light under measurement satisfies specific conditions. A PD detects the transmitted light of the fiber-optic Etalon and outputs the intensity of the light under measurement. A counter counts the number of peaks of the output of the PD. A CPU calculates the wavelength of the light under measurement based on the count value of the counter.

Abstract: Encoded spatio-spectral information processing is performed using a system having a radiation source, wavelength dispersion device and two-dimensional switching array, such as digital micro-mirror array (DMA). In one aspect, spectral components from a sample are dispersed in space and modulated separately by the switching array, each element of which may operate according to a predetermined encoding pattern. The encoded spectral components can then be detected and analyzed. In a different aspect, the switching array can be used to provide a controllable radiation source for illuminating a sample with radiation patterns that have predetermined characteristics and separately encoded components. Various applications are disclosed.

Abstract: An optical spectrum measuring apparatus is disclosed which is able to accurately measure the optical spectrum without an influence and to measure the light intensity per unit frequency without an influence of the change of the bandwidth of the wavelength because of the measured wavelength. The diffraction grating 4 emits the diffracted light with an appropriate wavelength corresponding to the incident angle after diffracting the parallel light. The outgoing light slit 6 passes the diffracted light with a length shorter than the slit width. The AD converter 9 measures the intensity of the diffracted light passed through the outgoing light slit 6. CPU 12 controls the incident angle and the width of the slit. The memory of the bandwidth of the wavelength 14 stores the bandwidth of the passed wavelength and the measured light intensity is adjusted with the bandwidth of the passed wavelength. Also the bandwidth of the passed wavelength is converted to the frequency and the measured light intensity is adjusted by the bandwidth of passed wave frequency.

Abstract: A multichannel imaging spectrometer for airborne geological, geophysical and environmental surveys in a moving vehicle. An optical scanner employs a rotating polygon allowing reduced scan optics with increased data acquisition efficiency. Multiple spectrometers integrally registered allow channelization of the received signal to optimize noise performance in the range from ultraviolet through infrared. Output data is in a form for recording and real time display. A staring mode configuration provides enhanced sensitivity by using a two-dimensional detector array and adjustable mirror orientation. A scanning mode embodiment employs a two-dimensional detector array with time delay integration and three-dimensional storage of temporal spatial data and spectral wavelength and intensity. Thus, all channels are acquired simultaneously, resulting in perfect band-to-band registration with continuous spectral curves over the field of view.

Abstract: A spectrophotometer of the type using a pulse motor to rotate a diffraction grating through a speed reducing mechanism has a capability of constructing a conversion table according to a program, by which table a rotation amount of the motor is converted to a corresponding wavelength of output light from a monochromator. The spectrophotometer is capable of designating a calibration mode in which an emission peak at a known wavelength of light from a light source is detected, a coefficient in a conversion equation is determined on the basis of the known wavelength of the emission peak and a rotation amount of the motor at a time when the emission peak is detected, and the determined coefficient is used to construct the conversion table which is then stored in a nonvolatile memory. In an analysis mode, a rotation amount of the motor is converted to a corresponding wavelength in accordance with the conversion table in the nonvolatile memory.
