Abstract: Provided is a spectrum measurement apparatus including a light source configured to emit light to a sample; a light detector configured to receive light, which is reflected or scattered from, or transmitted through the sample, and to measure an intensity of the received light, and a processor configured to reconstruct a spectrum of the sample for calibration while adjusting a value of a spectrum reconstruction parameter in response to the light detector receiving the light and measuring the intensity of the received light, and to determine an optimal value of the spectrum reconstruction parameter based on a similarity between the reconstructed spectrum of the sample for calibration and an original spectrum of the sample for calibration.

Abstract: Evaluating a fluid, including transmitting a light beam through the fluid to a detector while oscillating a path length traveled through the fluid by the light beam at a first frequency of oscillation; measuring a time-dependent intensity of incident light at the detector responsive to an interaction of the light beam with the fluid to produce a time-dependent intensity signal; filtering the time-dependent intensity signal to recover a path-dependent signal oscillating at the first frequency and indicative of an absorbance property of the fluid; and estimating a parameter of interest of the fluid using the path-dependent signal. The time-dependent intensity may be indicative of the true absorbance at multiple wavelengths of the fluid or fluids over the maximum path length difference so as to permit quantification of the percentages of each of these fluids. Filtering may include frequency filtering alone or using a phase-sensitive lock-in amplifier.

Abstract: A radiation measuring device for measuring electromagnetic radiation originating from an external source. The radiation measuring device includes, a spectrometer, a pyranometer, a pyrgeometer, a diffuser, and a control unit. The spectrometer and a pyranometer are positioned in a sensor zone of a housing of the radiation measuring device. The spectrometer measures visible shortwave radiation and near-infrared shortwave radiation received at the sensor zone. The pyranometer measures shortwave radiation received at the sensor zone. The pyrgeometer is positioned in another sensor zone of the housing and measures longwave radiation received at the other sensor zone. The control unit receives radiation measurements from the spectrometer, pyranometer, and pyrgeometer. A corrected amount of radiation received at the sensor zones of the radiation measuring device is determined from the received radiation measurements. Other embodiments are described and claimed.

Abstract: Dual laser frequency combs can rapidly measure high resolution linear absorption spectra. However, one-dimensional linear techniques cannot distinguish the sources of resonances in a mixture of different analytes, nor separate inhomogeneous and homogeneous broadening. These limitations are overcome by acquiring high resolution multi-dimensional non-linear coherent spectra with frequency combs.

Abstract: A method for correcting frequency offset in a dual comb spectroscopy system is provided. The method includes causing a first laser (L1) generator to transmit L1 pulses at a repetition rate of a first frequency and causing a second laser (L2) generator to transmit L2 pulses at a repetition rate of a second frequency. The method also includes interrogating a reference material using a combination of the L1 pulses and the L2 pulses and capturing reference cell pulses. The method further includes interrogating a material of interest using the L1 pulses and capturing material of interest pulses. The method includes determining a frequency jitter based on the captured reference cell pulses and the combination of the captured material of interest pulses and the L2 pulses.
