    Abstract: Spectroscopic system and spectrometers including an optical bandpass filter unit having a plurality of bandpass regions and a spatial encoding unit for encoding discrete frequencies of light passing through the optical filter. The incorporation of the encoding unit allows the spectrometer system to use a detector having one or a small number of elements, rather than using a more expensive detector array typically used with filter-based spectrometers. The system can also include an integrating chamber that collects the light that is not transmitted through the bandpass filter unit, and redirects this light to strike the filter unit again, resulting in a significant increase in the optical power passing through the filter. The integrating chamber maximizes the return of the reflected light to the filter assembly and minimizes optical losses. The integrating chamber may be an orthogonal design to preserve the optical geometric characteristics of the light entering the chamber.

    Abstract: A sample placed under a microscope is illuminated by light from a laser beam. Raman scattered light is passed back via a dichroic filter to various optical components which analyse the Raman spectrum, and thence to a CCD detector. The optical components for analysing the Raman spectrum include tunable dielectric filters in a filter wheel; a Fabry-Perot etalon; and a diffraction grating. These various components may be swapped into the optical path as desired, for example using movable mirrors, enabling the apparatus to be used very flexibly for a variety of different analysis procedures. Various novel analysis methods are also described.

    Abstract: Apparatus for inserting and removing several filters from an optical path and for determining at all times the instantaneous positional relationship of each filter with respect to the optical path includes a set of filters mounted on a carrier which is attached to a resonant piezoelectric system, and further includes reference tracks also located on the carrier and extending in the direction of the oscillatory motion and including a sequence of binary indicia progressing in the direction of the oscillatory motion. The reference tracks are read optically to produce a series of binary electrical signals which are processed to yield the instantaneous position of the carrier and filters with respect to a fixed optical path.

    Abstract: Monochromatic infrared radiation of variable wavelengths between 1.0 and 3.5 microns is directed upon a portion of a moving web, and the spectra of infrared radiation reflected from the web portion and of radiation transmitted through the web portion are separately measured by sensors located on both sides of the web. These spectra are combined to provide an absorption spectrum insensitive to any elastic scattering that is also present. Measures of the contents of the web constituents are generated by least-square fitting the individual absorption spectra of the constituents to the measured absorption spectrum of the web. Means for calibrating the reflectance and transmittance measurements and for keeping the sensor viewing windows free of dirt and dust are also disclosed.

    Abstract: A portable analysis spectrometer (10) for field mineral identification is coupled to a microprocessor (11) and memory (12) through a bus (13) and A/D converter (14) to display (16) a spectrum of reflected radiation in a band selected by an adjustable band spectrometer (20) and filter (23). A detector array (21) provides output signals at spaced frequencies within the selected spectrometer band which are simultaneously converted to digital form for display. The spectrum displayed is compared with a collection of spectra for known minerals. That collection is stored in memory and selectively displayed with the measured spectrum, or stored in a separate portfolio. In either case, visual comparison is made. Alternatively, the microprocessor may use an algorithm to make the comparisons in search for the best match of the measured spectrum with one of the stored spectra to identify the mineral in the target area.

    Abstract: A multi-wavelength time-sharing apparatus usable in various different configurations of optical measuring equipment to provide a plurality of time-shared optical channels and including appropriate circuitry. The apparatus employs a turbine-driven filter wheel having a shaft position-encoding arrangement consisting of a hollow shaft portion which is internally illuminated. The hollow shaft portion has two sets of spaced apertures cyclically communicating with respective angularly spaced pairs of externally fixedly mounted phototransistors which are sequentially illuminated as the shaft portion rotates and which produce timing pulses which drive Schmitt triggers, which, in a typical embodiment, in turn produce pulses compatible with a logic circuit employed to decode the phototransistor signals into triggers for driving a 4-channel switched gain equalizer, a dark current clamp, and detector gates. Appropriate selection of the signals enables the instrument to function as a fluorometer or a spectrophotometer.

    Abstract:  一次元的に配列された複数のPDを複数のグループに区分し、グループ毎に、当該グループに属する全てのPDの表面がそれらPDに入射する光の波長域の中で透過率が極大を示すような透過率特性を有する反射防止膜で被覆されるように、グループ毎に反射防止膜の膜構造(材料又は厚さの少なくとも一方)を変える。特にSi基板(102)上のSiO 2 膜層(104)、Al 2 O 3 膜層(105)は全PDに共通とし、その上の層を波長によって変え、さらに紫外波長域では波長に応じて細かく膜構造を変えることで、製造工程の複雑さを極力回避しながら、高い透過率(入射光が光電変換領域にまで到達する率)を上げることができる。これにより、PDA検出器を用いた分光計測装置において、特に紫外波長域でも漏れなく高い感度を達成することができる。
