Abstract: PURPOSE: To detect an image as the display of the presence of the polymer on a matrix by impregnating a solid phase having an objective polymer fixed thereto with a liquid phase substrate and exposing a liquid phase chemoluminescent substrate to a phosphor screen. CONSTITUTION: A phosphor screen 16 is excited by the light energy of laser 25. The beam emitted from the laser passes through a collimator lens 26 to be corrected and is deflected by a mirror 27. Next, the beam is gathered on the screen 16 by the lens 28 controlled by a micrometer 29. A translation device 21 bringings about the scanning of the total length surface of the screen by the beam. The energy emitted from the phosphor screen by infrared excitation is deflected to an optical photomultiplier tube 32 to which high voltage power is supplied 33 by a cold mirror 30 through a short-pass filter 31 and, further, the signal from the photomultiplier tube 32 is turned toward an oscilloscope 34 and a voltmeter 35 to be translated to a visible form by a display 36 having a computer 37.
