Abstract: A tristimulus colorimeter employs a multiplexed dual slope integrator digital voltmeter wherein unknown and reference light beams are compared by sequentially applying unknown and reference electrical signals representative of the two respective light beams to the non-inverting and inverting inputs, respectively, of the integrator amplifier. Moreover, a compensating circuit provides for compensation of the colorimeter output signals with respect to reflectance error encountered in the optics portion of the colorimeter with such compensation being provided as a function of the light intensity from the colorimeter light source.

Abstract: A spectroradiometer having two detectors and a pair of monochromator channels for measuring the intensity of light emitted from an unknown source. One of the monochromator channels is illuminated with light from a reference source, and a fraction of the resulting monochromatic beam is received by the first detector to produce a reference signal. Another fraction of the monochromatic beam is combined with light from the unknown source by directing the two to opposite sides of a rotating chopper and then alternately through the other monochromator channel to the second detector. The second detector produces successive signals respectively corresponding to the intensity of the light from the unknown source and the intensity of the light from the reference source. The ratio between these signals is multiplicatively combined in an electrical circuit with the reference signal from the first detector, thus providing a measurement of the unknown intensity. In cases in which conventional detectors are employed, certain preferred embodiments of the invention include an additional chopper for the light illuminating the monochromator channels to enable a correction for background or dark signals from the detectors.

Abstract: A fluorescence radiation detector of the Fraunhofer line discriminator type. A sky telescope and an earth telescope each form radiation beams which are directed to a single optical chopper. The chopper sequentially directs each beam through a single Fabry-Perot filter centered at the Fraunhofer line and a single neutral density filter. The chopped segments are recombined to form a beam containing A, B, C, and D portions in time sequence where: A the direct solar intensity within the continuum; B the direct solar intensity inside the selected Fraunhofer line; C the reflected solar intensity inside the selected Fraunhofer line; and D the reflected solar intensity in the continuum. A single photomultiplier tube with a blocking filter in front receives the beam and produces corresponding sequential electrical pulses which are electronically processed to yield fluorescence (p) from the equation

Abstract: A measuring light source includes a hollow body having a diffusely reflective inner surface. Formed in the hollow body are a concave, concave mirror-shaped illumination space, a tubular light shaping space, and a concave, concave mirror-shaped light exit space, which have a shared axis. A light source for generating light is at least partially situated in the illumination space. The light exit space has a light exit. The illumination space and the light exit space with their concave mirror shapes are situated opposite one another and are connected by the tubular light shaping space. A diffusely reflecting reflective disk for reflecting the light, reflected from the inner surface of the hollow body situated in the light exit space, through the light exit to outside the hollow body is situated in the hollow body.

Abstract: Technologies are described for monitoring characteristics of layers of integrated computational elements (ICEs) during fabrication using an in-situ spectrometer operated in step-scan mode in combination with lock-in or time-gated detection. As part of the step-scan mode, a wavelength selecting element of the spectrometer is discretely scanned to provide spectrally different instances of probe-light, such that each of the spectrally different instances of the probe-light is provided for a finite time interval. Additionally, an instance of the probe-light interacted during the finite time interval with the ICE layers includes a modulation that is being detected by the lock-in or time-gated detection over the finite time interval.

Abstract: Two dimensional (2D) optical spectroscopy, wherein the spectrum has an excitation and an emission axis, reveals information formerly hidden in one-dimensional (1D) optical spectroscopy. However, current two dimensional optical spectroscopy systems are complex laboratory arrangements and accordingly limited in deployment. According to embodiments of the invention a monolithic platform providing significantly reduced complexity and increased robustness is provided allowing for “black-box” modules allowing commercial deployment of 2D optical spectroscopy instruments. Additionally, the invention supports high pulse repetition rates as well as one quantum and two quantum measurements under electronic control.
