| 20120113409 | RANGE FINDER - A laser range finder includes: a light source emitting light from a linear light-emitting portion with making a divergent angle of the light larger in a transversal direction of the light-emitting portion than in a longitudinal direction thereof; an objective lens projecting the light onto a target object and converging reflection light; a partial reflection member disposed between the light source and the objective lens and having a partial reflection surface composed of a transmitting area transmitting light emitted from the light source and receiving areas reflecting reflection light; and a photodetector detecting the reflection light reflected by the receiving areas; wherein the light source and the partial reflection member are disposed with making the longitudinal direction of the light-emitting portion disposed substantially perpendicular to a longitudinal direction of the transmitting area as seen along an optical axis. | 05-10-2012 |
| 20110109963 | RELAY ZOOM SYSTEM - A relay zoom system includes, in order from an object side, a first lens group having a positive refractive power and a second lens group having a positive refractive power. Furthermore, in the relay zoom system, the first lens group and the second lens group are each made up of at least two positive lenses and one negative lens. The first lens group and the second lens group in the relay zoom system are configured so as to move along an optical axis when magnification is varied from a lower magnification edge state to a higher magnification edge state. | 05-12-2011 |

| 20100290029 | RANGE-FINDING DEVICE - A range-finding device includes: a light emitting unit that continuously emits measurement light to be used for distance measurement toward a measurement target object; a light-receiving unit that receives reflected light reflected by the measurement target object; a calculation unit that repeatedly calculates a distance to the measurement target object over predetermined time intervals by using the reflected light; a display unit at which an update of the distance is displayed each time the distance is calculated by the calculation unit; and a display update control unit that prohibits the update of the distance on display at the display unit and sustains the display of the previously calculated distance at the display unit according to a change in the most recently calculated distance calculated most recently by the calculation unit relative to the previously calculated distance having been calculated previously by the calculation unit. | 11-18-2010 |
| 20090115992 | Distance measuring apparatus - A distance measuring apparatus, which can achieve reduction in cost and size and perform measurement ranging from short-distance to long-distance accurately, includes an unit outputting first pulsed light L | 05-07-2009 |
