Abstract: The present invention provides an apparatus and method for enhancing the system response of a photodetector array based spectrometer. For a spectrometer with a given system response curve, secondary light sources are provided to improve the system response in the spectral ranges where the dynamic range is less than at the peak of the curve. In one embodiment, multiple light sources can be combined by means of multiple branches of fibre optic bundles. The secondary light sources may be used in combination with suitable shaping filters and/or masks to further flatten the system response.

Abstract: A tunable spectral source includes an enclosure having first and second apertures; an optical dispersive element positioned in the enclosure; and multiple pixel source elements that are individually controllable for selectively directing one or more broadband light signals through the first aperture to irradiate the optical dispersive element. Each of the broadband light signals irradiates the optical dispersive element at a unique angle of incidence. The optical dispersive element disperses the broadband light signals into spectral component signals at dispersion angles that are dependent upon the angle of incidence of each broadband light signal that irradiates the optical dispersive element. The portions of the spectral component signals that are emitted through the second aperture are determined by selecting one or more particular pixel source elements to irradiate the optical dispersive element.

Abstract: A cost effective multicolor sensor and related software achieves a spectral response that closely approximates an ideal photo response to measure optical measurement, for example photosynthetic photo flux density (PPFD). The spectra error of the sensor is smaller than that of the best commercially available sensor at a significantly reduced cost. The sensor may include an 8×2 array of filtered photodiodes and spectral photo sensors that are linearly combined with the appropriate mathematically determined coefficients to create a corrected spectral response curve that has a spectral error much smaller than the best commercial available sensors made by physical coating methods for the entire desired range.

Abstract: A series combination of a shortwave pass (SWP) filter and a longwave pass (LWP) filter is provided in an arrangement where the filters are separately and independently controlled by voltages applied to the respective filters. The applied voltages modify the response profile of the associated filters, where changes in the voltage applied to the SWP filter changes its cut-off wavelength λS and changes in the voltage applied to the LWP filter changes its cut-on wavelength λL (the bandwidth of the combined arrangement between the span between λL and λS). The ability to independently tune both the SWP and LWP filters allows for the combined result of their series combination to modify both the center wavelength (CWL) and bandwidth (BW) of the overall filter resulting from their combination.

Abstract: An emission device (1) for emitting a light beam of controlled spectrum, includes: at least two separate light sources (Si to N) each emitting a light beam of wavelength λ1 or λ2, and spectral multiplexing elements (25). The spectral multiplexing elements (25) include an optical assembly (25) formed from at least one lens (25) and/or an optical prism. The optical assembly (25) has chromatic dispersion properties and moves the light beams spatially closer together. Moreover, each light beam having at least wavelength λ1 or λ2 propagates in free space from the corresponding light source (Si to N) to the optical assembly (25). Therefore the emission device (1) is particularly robust. It can have small dimensions and be produced at low cost.
