摘要： A high precision laser range finder comprises an APC loop for eliminating a timing jitter problem due to different reflections on a target. The APC loop comprises a laser receiver, a peak holding circuit, an integrator and a high voltage generator. The peak holding circuit is connected with the laser receiver for detecting a signal strength outputted from the laser receiver. The high voltage generator provides the laser driver and laser receiver with voltage so as to control the strength of the emitted laser pulse signal of the laser driver and the gain of the avalanche photo-detector. The integrator is used to eliminate the steady error in the APC loop. Furthermore, a time to amplitude converting circuit comprises an AJD converter for obtaining a distance data and then filtering in a microprocessor to increase the measurement accuracy.

摘要： A beam combiner includes a first lens and a second lens coated with specific optical films. The first color light beam enters the first lens via a first incidence surface with an incidence angle of Brewster's angle. The second color light beam enters the first lens via the second incidence surface with an incidence angle of zero degree. The third color light beam enters the second lens via the third incidence surface with an incidence angle of zero degree.

摘要： A heat sink assembly including a heat sink having a plurality of equi-distantly spaced cooling fins. The heat sink body has a depression on one side for receiving a cooling and is fixedly provided above integrated circuits of the electronic product, with a layer of thermal conductive plate disposed therebetween. The heat generated by the integrated circuit elements during operation process is transferred to the cooling fins via the thermal conductive plate. Simultaneously, the cooling fan draws in air, which is discharged, via an air outlet thereof towards the cooling fins to dissipate the heat of the cooling fins. The cooling fan can be disposed directly above the heat sink body to enhance heat dissipation efficiency. A single cooling fan will suffice to achieve good heat dissipating effects, thus reducing manufacturing cost.
