Abstract
A diagnosis apparatus comprises a shutter ( ) disposed between a light source ( ) and a lens ( ) opposed to biological tissue ( ); a multi-channel spectrometer (polychromator) ( ) for detecting a light emitting plume ( ); a photodetector ( ) for detecting a portion of a laser pulse from the light source ( ); an oscilloscope ( ) which monitors an output from the photodetector ( ) to thereby measure a delay time of a gate trigger pulse supplied to a high-speed gate image intensifier ( ); a pulse generator ( ) capable of independently and freely adjusting the delay times of two output pulses in synchronization with the laser pulse; a gate controller ( ) connected to the pulse generator ( ) and the oscilloscope ( ); the high-speed gate image intensifier ( ) intensifying and imaging the output of the multi-channel spectrometer ( ) whose gate is opened by the gate controller ( ) over a period on the order of nanosecond; a CCD camera ( ) capturing an output image from the high-speed gate image intensifier ( ); and a data-processing apparatus comprising a frame image data storage ( A) which inputs spectroscopic image data of one frame from the CCD camera ( ) as a time-series analog signal, and converts the analog signal to a digital signal for transmission to a computer ( ).
