Acoustooptic snapshot PROM: a real-time optical-signal spectrum analyzer
Abstract:
This paper describes a system which performs real-time optical processing of electrical signals. The signals of interest are recorded in a raster format on the Itek PROM (Pockels Readout Optical Modulator), a light addressed electrooptic imaging device. The PROM is then read out with laser light to perform optical Fourier transformation, achieving spectrum analysis in near real time. A technique called acoustooptic snapshot recording is used to generate the required low distortion raster at rf bandwidths.

Inductively Coupled Plasma Atomic Emission Spectroscopy: Instrumentation
There are three main types of inductively coupled plasma atomic emission spectroscopy (ICP-AES) instruments: sequential, simultaneous multichannel, and Fourier transform instruments, with the latter being less commonly used.

If the sampling frequency is below the Nyquist rate, these replicas overlap, preventing the original signal...
Raman Spectroscopy Instrumentation: Overview
The monochromatic laser source, typically using visible or near-infrared radiation, generates a highly focused beam of light. This light interacts with the molecules of the sample, scattering some of the light. Liquid and gaseous samples are usually tested in ordinary glass capillaries, while solids can be analyzed as powders packed in capillaries or as potassium...
