Abstract: Disclosed herein are various energy conveyance systems that are able to convey energy along different optical paths to non-overlapping regions of a sensor. A system can include an objective optics system that collects and focuses energy, and can further include steering optics that are configured to divert an optical path of at least a portion of the energy that is collected via the objective optics system. The steering optics may cause different portions of energy collected via the objective optics system to be delivered as focused field images to non-overlapping or similar sections of a sensor.

Abstract: An apparatus and method for measuring Raman-type spectra using optical dispersion to convert an optical spectrum into a waveform which can be detected directly in the time domain without the use of a conventional spectrometer. In the example of stimulated Raman spectroscopy, the apparatus and method exposes a sample to a chirped, pulsed probe beam and a Raman pump beam and the resulting Raman spectra is detected by an optical detector in the time domain, and analyzed. Alternatively, the Raman spectra from the probe and pump beams is chirped with a dispersive element prior to detection and analysis. Each probe pulse provides a snapshot of the Raman spectrum that is sampled in time so that neither repetitive waveforms nor static samples are required. Therefore, high speed acquisitions and high throughput assays can be conducted. To facilitate detection, these spectral signals can also be amplified using distributed Raman amplification directly in the dispersive element.

Abstract: Preferred embodiments of the invention provide for methods and systems of 2D spectroscopy using ultrafast, first light and second light beams and a CCD array detector. A cylindrically-focused second light beam interrogates a target that is optically interactive with a frequency-dispersed excitation (first light) pulse, whereupon the second light beam is frequency-dispersed at right angle orientation to its line of focus, so that the horizontal dimension encodes the spatial location of the second light pulse and the first light frequency, while the vertical dimension encodes the second light frequency. Differential spectra of the first and second light pulses result in a 2D frequency-frequency surface equivalent to double-resonance spectroscopy. Because the first light frequency is spatially encoded in the sample, an entire surface can be acquired in a single interaction of the first and second light pulses.

Abstract: A spectroscopic analysis of a sample includes arranging the sample in a resonator cavity for transmitting cavity mode frequencies with a cavity mode frequency spacing, coupling pulsed source light into the resonator cavity, with the source light including source comb frequencies with a source frequency spacing, coupling pulsed transmitted light out of the resonator cavity, and spectrally resolved detecting the transmitted light with a detector device. The cavity mode frequency spacing and the source frequency spacing are detuned relative to each other, so that the transmitted light includes transmitted comb frequencies with a spacing larger than the source frequency spacing. The detecting feature includes collecting spectral distributions of the transmitted light in dependence on relative positions of the cavity mode frequencies and the source comb frequencies. The cavity mode frequencies and the source comb frequencies are varied relative to each other and different transmitted comb frequencies are individually resolved.
