Fast cooling to deep supersaturation for solvent crystallization seems to have two major components. One involves mainly the thermodynamics or phase equilibrium chemical thermodynamics of deep supe...

Our previous efforts in Hadamard transform Raman imaging in the visible spectral region began with stationary two-dimensional (2D) Hadamard encoding masks and evolved to moving 2D Hadamard encoding masks. We have now advanced to using a spatial light

One observes that the early developments in chemistry depended upon the improvement of the balance. Major milestones in chemistry can be related directly to improvements in balance design, precision, and accuracy. In a similar manner, the past three

Temporal systematic errors result from the use of a stationary Hadamard encoding mask in a Hadamard transform spectrometer when the time between encodements is made too short relative to the mask response time. These errors have been characterized an

A method of predicting point and path-averaged ambient air VOC concentrations is described. This method was developed for the case of a plume generated from a single point source, and is based on the relationship between wind directional frequency an

The effect of a uniform bistable optical transmission defect in the encoding mask on the multiplex efficiency is investigated for solid-state Hadamard transform spectrometry with thermal detection. It is demonstrated that encoding masks which possess

Near-infrared Hadamard transform Raman spectrometry was performed to demonstrate the advantages gained using a recently developed 255 element polymer-dispersed-liquid-crystal (PDLC) optical-shutter-array as a stationary Hadamard encoding mask. Spectr

A digital micromirror device (DMD™) was tested to demonstrate its potential as a multiplexing device for the simultaneous detection of visible electromagnetic radiation. Using a Visual Basic program, four sections of the DMD were illuminated by a l

An adaptive digitally tuned light source is disclosed, in the form of a de-dispersive imaging spectrograph in both the visible and near infrared spectral regions. The devices are capable of illuminating a sample with appropriate energy-weighted spect
