Abstract: PROBLEM TO BE SOLVED: To provide a photon counting device, a photon counting system, and a photon counting method which have high imaging precision and which can decrease the amount of image data accumulated.
SOLUTION: A bright spot center calculating part 22 calculates the center of a bright spot based on brightness data which relates to the alignment of a light receiving element 110 and which shows intensity of brightness. A barycenter information calculating part 23 calculates barycenter information based on the brightness data. A bright spot barycenter calculating part 32 calculates the barycenter of the bright spot using the barycenter information and the information of the center position of the bright spot. As a result, the position of the bright spot of a fluorescent material 4 can be accurately measured thereby increasing the imaging precision. In addition, since only the brightness data, the information of the center position of the bright spot, and the barycenter information need to be stored in a data storage part 31 instead of storing image data at a preliminary step toward showing the bright spot, the amount of image data accumulated can be reduced.

Abstract: PROBLEM TO BE SOLVED: To provide a signal processing circuit which converts an inputted analog signal into a digital signal and can binarize it. SOLUTION: In a binarization period, a reference voltage Vref is set to VBI and the output of a comparator 60 is inputted to a binarized result storage part BINL. The binarized result storage part BINL temporarily stores a binarized signal outputted from the comparator 60 and outputs the stored binarzied signal. In an A/D conversion period, the reference voltage Vref is set to VAD1 or VAD2 and the output of the comparator 60 is inputted to a control part 70. The control part 70 temporarily stores a controlled variable as a digital signal and outputs the stored digital signal.

Abstract: PROBLEM TO BE SOLVED: To provide a person collation device capable of registering a person in a short time. SOLUTION: This person collation device is provided with an image pickup part 50 for picking up the image of the pattern of a prescribed part of the body of a person and obtaining the image for reference at the time of registering the person and picking up the image of the pattern of a prescribed part of a collation object person and obtaining the image for collation at the time of collating the person and an arithmetic processing part 60 for obtaining a similarity degree between the image for the reference and the image for the collation and judging whether or not the collation object person is the registered person based on the similarity degree. The arithmetic processing part 60 obtains the similarity degree by electronically Fourier-transforming the plural images for the reference obtained for the plural persons and the image for the collation, electronically overlapping the Fourier transformed results of the plural images for the reference, electronically multiplying the result of the overlapping and the Fourier transformed result of the image for the collation and then, electronically inversely Fourier-transforming the multiplied result.

Abstract: PROBLEM TO BE SOLVED: To extract the sectional image information of the part existing at the optional depth of a three dimensional object by high space resolving power. SOLUTION: A laser beam whose wave length varies with the passage of time is emitted from a semiconductor laser 24, and branched into a measured object 36 and the side of the whole reflection mirror 34 by a beam splitter 30. The interference light image of a light path length decided by the characteristics of variation of the wave length of a laser beam is formed of the reflection beam of the measured subject 36 and light phase modulated by a phase modulater 32 on the beam splitter 30. After the interference light image is converted into an electric charge distribution through a space light modulating tube 44, light read out from an other laser generating device 48 is irradiated onto the space light modulating tube 44 to read out the interference light image corresponding to the electric charge distribution for photographing it by a video camera 58. The characteristics of variation of the wave length of the laser beam is varied to change the light path length for extracting the sectional image information of the optional part in the direction of depth of the measured object 36.

Abstract: PURPOSE:To obtain the spatial optical modulator which functions to modulate light spatially in parallel and also store it. CONSTITUTION:The spatial optical modulating element formed by laminating a photoconductive layer 3 and a modulating material with a self-threshold function in order is provided between a couple of transparent electrodes 21 and 22, and a variable voltage supply means 6 where an optional voltage value is settable is connected between the couple of transparent electrodes 21 and 22. Thus, the spatial optical modulating element is constituted by using the modulating material with the self-threshold function and a variable voltage is applied between the transparent electrodes 11 and 12, so the threshold level is optionally settable.

Abstract: PURPOSE:To shorten a processing time to continuously output the output by converting an input or feedback signal to an optical image and multiplexing/ expanding and forming the image on the photoelectric surface of a space optical modulating tube and performing the data processing by optical operation. CONSTITUTION:The input from a CPU 351 is written on a space optical modulating tube (T) 301 through pattern presenting devices 361 and 362 and expanding/ multiplexing image forming systems 311 and 312. Shutters S1 and S2 are opened and closed in a prescribed order to perform a prescribed operation through Ts 301, 302 and 303 by a monochromatic light, and the result is inputted to the CPU 351 from a reverse multiplexing image forming system 313. The CPU 351 performs the threshold processing and the feedback processing to complete inscription. Remembrance is performed through the system 312 by a prescribed operation in Ts 301, 302 and 303. Thus, the data processing time is shortened and the output is continuously outputted.
