HDR spectrum
Experimental. Opens a new window (see below) for acquiring high
dynamic range (HDR) spectra.
A sequence of spectra are obtained at
increasing exposure times and combined to form a single high dynamic
range spectrum. The result is qualitative, but can provide information on
spectral purity and ASE (amplified spontaneous emission).
Background images must be obtained before generating HDR spectra. The
first time an HDR spectrum is acquired, a dialogue box will pop up asking
you to block the light into the fibre, and to press OK. A sequence of
background measurements will be acquired and stored.
Single
Generates a single HDR spectrum.
If background data has not been
obtained, you will be prompted to block the light into the fibre so that the
