Abstract: An attachment lens is arranged in a stage subsequent to a scanning lens. After a laser beam is converged by the scanning lens, the laser beam is converted into a parallel beam by the attachment lens. When the scanning lens is displaced in a direction perpendicular to an optical axis of the laser beam, a traveling direction of the laser beam is bent by a predetermined angle immediately after the laser beam passes through the scanning lens. Then, the traveling direction of the laser beam is further bent by a predetermined angle in the same direction by the passage of the laser beam through the attachment lens. Accordingly, a final swing angle of the laser beam outgoing from an outgoing window is increased by a swing angle imparted by the attachment lens compared with the case where the attachment lens is not arranged. One of lens surfaces of the attachment lens is formed in a toroidal surface, which allows the laser beam to have a long outline in a vertical direction.

Abstract: When detecting fluorescence of a bead chip array, reflected light from a bead is detected at the same time, so as to recognize the bead position. The reflected light can be detected in a similar manner for all beads, regardless of the presence or absence of a fluorescent substance. If the positions of all beads are detected, accurate detection can be achieved by quantifying only the fluorescence at the detected positions. The fluorescence wavelength alone is detected by a first detector using a wavelength selection filter. Other wavelengths are detected by a second detector, thereby obtaining the reflected light. Data on the reflected light is processed into an image for obtaining the bead profile, the bead position is recognized by detecting the center position based on the profile, and the fluorescence is quantified based on the bead position.

Abstract: A rifle scope system allows adjustment of the scope while a shooter maintains the shooting posture and the scope sight picture. The scope system comprises an adjustment system comprising an electromechanical mechanism that responds to a signal from a remote controller manipulated by the shooter without having to significantly disturb the shooting posture. The adjustment system allows the shooter to adjust the scope's point of aim to coincide with a bullet's point of impact at a target. Such adjustment can be performed either by the shooter. Alternatively, such adjustment could be performed by a processor configured to adjust the point of aim based on a ballistic parameter associated with the bullet or the shooting environment. The adjustment system allows such processor-determined adjustments to be effected in a quick manner.
