[Application of AOTF in spectral analysis. 4. Enhancing spectral resolution of AOTF atomic emission spectrometer with FSD].

Using Fourier self-deconvolution (FSD) to enhance spectral resolution of AOTF atomic emission spectrometer is described. Choosing the appropriate deconvolution parameters: full width at half maximum (FWHM) and breaking point, the FWHM of the simulated overlapping peaks could be decreased by a factor of 3.5, and the peak height by a factor of 5, but retaining the peak position.

[Application of AOTF in spectral analysis. 2. Application of self-constructed visible AOTF spectrophotometer].

The performances of a self-constructed visible AOTF spectrophotometer are presented. The wavelength calibration of AOTF1 and AOTF2 are performed with a didymium glass using a fourth-order polynomial curve fitting method. The absolute error of the peak position is usually less than 0.

[Application of AOTF in spectral analysis. 1. Hardware and software designs for the self-constructed visible AOTF spectrophotometer].

A self-constructed visible spectrophotometer using an acousto-optic tunable filter(AOTF) as a dispersing element is described. Two different AOTFs (one from The Institute for Silicate (Shanghai, China) and the other from Brimrose(USA)) are tested. The software written with visual C++ and operated on a Window98 platform is an applied program with dual database and multi-windows.
