Intensified silicon photodiode array

The performance characteristics of four optoelectronic image detectors (OIDs) are discussed. The detectors discussed are the silicon intensified target vidicon (SIT), the intensified SIT, the intensified silicon photodiode array detector (ISPD), and the self-scanned photodiode array detector. The main objective of the paper is to provide research workers interested in applying OIDs to a particular application with comparative performance information so that the best detector for a particular application may be selected. 

We employ method B to study effects of this type. In this mode, our apparatus yields relative high-resolution fluorescence spectra at different time windows after excitation of the sample by the 355 nm pulse. The spectra are acquired by the upconversion method. The upconverted fluorescence spectrum is recorded simultaneously at all monitored wavelengths by an optical multichannel analyzer. It is constructed from a poly-chromator (HR320 Instruments SA) and an intensified silicon photodiode array detector (Princeton Applied Research Model 1412). The detector is interfaced to our Cromemco computer.

SPD) and draw comparisons to PMT arrays as used in classical pol-ychromators. To a lesser extent, some comparisons are drawn with silicon intensified target vidicons (SIT) and intensified selfcanning photodiode array detectors (ISPD). A similar evaluation of the SPD for spectrophotometry and spectrofluorometry was recently published elsewhere (41). 

The 355-nm pulse is used to excite the sample, and the continuum segments (probe pulses are used to monitor the resulting AA. The probe pulses, after passing through the sample are then focused into a monochromator which has mounted to its output a two dimensional silicon intensified target photodiode array connected to a computer. With the monochromator set at 430 nm, Sundstrom et. al. (24) directly measured the population growth rate of the lowest triplet state of acridine, which when calculated from the data illustrated in Figure 4 is 3 x 10 0 sec l. 

Limited comparisons are also drawn for silicon intensified target vidicons (SIT) and intensified self-scanning photodiode array detectors (ISPD).
