Abstract

PURPOSE: To establish the detector enabling highly accurate measurement in small size, by detecting the shadow of particles of bram curtain of laser light with CCD sensor.
CONSTITUTION: The detector consists of the laser beam 4, beam expander 5, cylindrical lens 6, and primary dimension charge coupling element(CCD)7, the charge polarization type ink jet unit is located vertical to the beam curtion of laser light, and the shadow of the ink particles 1 is detected with CCD7. For example, the laser light extended with the beam expander 5 consisting of two lenses is made to one line with the cylindrical lens 6 to constitute the laser beam curtain. Further, the ink particles 1 jetted from the head 8 is charged at the charge electrode 9 and deflected at the deflection electrode 10 and further, crosses over the curtion, then the shadow on the apperture of CCd7 is detected to know the position of the particles 1.
