Abstract
A temporal spectral photometer for use in obtaining spectral and temporal information simultaneously of an ultrafast pulse of luminescent light emitted from a sample upon excitation thereof includes an excitation section and a detection section. The excitation section includes a picosecond laser for exciting the sample to emit luminescent light and imaging optics for imaging the emitted light. The detection section includes a pin hole slit through which light from the imaging optics is admitted, a streak camera tube, an optical system including a grating for forming an image of the pin hole slit on the photocathode of the streak camera tube and at the same time dispersing the light admitted through the pin hole slit into its component wavelengths, a micrometer assembly mechanically coupled to the grating for selectively changing the wavelength region of dispersed light impinging on the photocathode, a video camera, a camera lens system for imaging the output image formed on the phosphor screen of the streak camera tube onto the input end of the video camera, a digital temporal analyzer coupled to the output of the video camera for digitizing and analyzing image information from the video camera and a video monitor coupled to the output of the temporal analyzer for displaying the analyzed data.
