Title: Recognizing device for vehicle number plate
Inventor: SAKAI KENICHI
IPC: G03H1/16
Filed: 1993-12-13
Abstract: PURPOSE:To recognize a number plate at high speed by providing a recognizing means which recognizes the number plate by means of optical pattern matching through the use of a hologram filter based on a photographed image. CONSTITUTION:An input image (b) is made incident to the hologram filter 21 generated by a hologramfilter generation optical system and the correlative operation of the reference image (a) such as Arabic numerals, etc., indicating the vehicle number recorded in the hologram filter 21 with the input image (b). The correlative operation of the reference image (a) with the input image (b) is executed by permitting diffracted light beams which pass through the hologram filter 21 so as to be diffracted to pass through a inverse Fourier transform lens 29. When light to which the inverse Fourier transform is operated coincides with the numerals of the reference image, a part corresponding to the numerals becomes a luminescent point on a correlative result output surface 31. The luminescent point is recognized by an optical detecting element such as CCD, etc., so that the numerals are specified.

IPC: H01L29/78
Filed: 1990-11-21
Abstract: PURPOSE:To simplify alignment at the time of local laser annealing without using a mask by forming an alignment pattern on a base film of a crystallize film and utilizing transmitted light of laser light to perform alignment. CONSTITUTION:A sample 17 with alignment patterns formed on both ends of a crystallized region is set on a stage 16, and two alignment laser beams 10 are applied to the two alignment patterns. Transmitted light from the sample 17 is sensed by a photodetector 12 placed on a back of a substrate.

A signal sensed by the photodetector 12 is calculated by a signal processing circuit 13, and the results are transmitted to a feedback mechanism 14. The feedback mechanism 14 instructs a scanning direction of the stage 16 to a stage controller 15 so that the transmitted light is maximum. This process allows automatic alignment.
