Abstract: An optical spectrum analyzer (OSA) 10 sequentially or selectively samples (or filters) a spectral band(s) 11 of light from a broadband optical input signal 12 and measures predetermined optical parameters of the optical signal (e.g., spectral profile) of the input light 12. The OSA 10 is a free-space optical device that includes a collimator assembly 15, a diffraction grating 20 and a mirror 22. A launch pigtail emits into free space the input signal through the collimator assembly 15 and onto the diffraction grating 20, which separates or spreads spatially the collimated input light, and reflects the dispersed light onto the mirror 22. A λ/4 plate 26 is disposed between the mirror 22 and the diffraction grating 20. The mirror reflects the separated light back through the λ/4 plate 26 to the diffraction grating 20, which reflects the light back through the collimating lens 18. The lens 18 focuses spectral bands of light (λ1–λN) at different focal points in space. One of the spectral bands 11 is focused onto a receive pigtail 28, which then propagates to a photodetector 30. A pivoting mechanism 34 pivots the diffraction grating 20 or mirror 22 about a pivot point 36 to sequentially or selectively focus each spectral band 11 to the receive pigtail 28. A position sensor 42 detects the displacement of the diffraction grating 24 or mirror.

Abstract: Color measurement using compact devices is described herein. A color measurement device can include a diffraction grating that receives light reflected from a surface whose color is being measured. The diffraction grating is responsive to a control signal to split selected components from the reflected light and to admit the components in sequence to a sensor. The components can correspond to a selected wavelength or frequency of the reflected light. The sensor measures the energy or power level of each of the admitted components. The device can support determining a spectral representation of the color of the surface by generating output signals representing the various energy or power levels of each component of the light reflected from the surface.

Abstract: The present invention is directed to method and apparatus for measuring the spectral characteristics of an object from a formed object generated input signal. The method comprises the steps of directing the input signal onto a diffraction grating. Diffracted signals are directed to a resonant mirror assembly for sequentially focusing a select diffracted signal. From that focused select diffracted signal, a spectral characteristic of said object is determined. Each said spectral characteristic is associated with each corresponding focused select diffracted signal and the associated signals are published. The apparatus is an improved spectrometer comprising a fiber cable assembly for receiving an object generated input signal and a diffraction grating. A resonant mirror assembly sequentially focuses a select diffracted signal, a sensor sensing which diffracted signal has been focused from the diffraction grating. An analyzer coupled with the sensor determines a spectral characteristic of the object from said select diffracted signal.

Abstract: To achieve a given spectral resolution with reduced detector size and commercially available pixel pitches, the Raman spectrum is shifted across the detector array such as by one of the following methods: 1) tuning the excitation wavelength; 2) rotating the grating; 3) displacing the effective input slit (fiber) and acquiring the spectrum under stepped displacement conditions; and 4) displacement of a lens relative to input fiber to displace effective input slit relative to the detector. A composite spectrum is formed and deconvolution of the entrance aperture image and/or pixel masking is then used.

The illustrative embodiment of the present invention, like the prior art, uses a grating or prism to disperse the spectral components of a multi-wavelength signal, and then uses a reciprocating or rotating mirror to direct the spectral components, one at a time, into a photodetector. The illustrative embodiment uses a telescope between the grating and the mirror to improve the spectral resolution of the system.
