Abstract: The described technology relates to a light detection and ranging (LIDAR) device. The LIDAR device can include a transmission unit configured to emit a first signal, a first lens unit configured to convert the first signal into parallel light, a reflection unit configured to adjust a direction of the converted first signal and a second lens unit configured to enable the first signal to have the same focal plane even when a reflection angle of the reflection unit changes. The LIDAR device can also include a third lens unit configured to convert the first signal passing through the second lens unit into parallel light, a fourth lens unit configured to increase an angle of the first signal passing through the third lens unit and a reception unit configured to receive a second signal reflected by an object after passing through the fourth lens unit.

Abstract: A laser light source shutter system includes a light source, a variable focus optical element to transmit a beam emitted from the light source, a pinhole located on an optical path through which the beam travels from the variable focus optical element, and a controller to control a transmission and blocking of the beam by controlling a focal length of the variable focus optical element to be equal to a distance between the variable focus optical element and the pinhole or to be equal to other distances different from the distance. Therefore, a laser light source shutter free from vibration can be realized electronically with a low cost and a high light-blocking rate using a variable focus optical element such as a variable focus lens and a variable focus mirror.

Abstract: A method and an apparatus for calculating an offset of a Wheatstone bridge type sensor are described. The offset calculation method includes measuring resistances between nodes of a Wheatstone bridge type sensor, calculating an offset of the sensor using the measured resistances and providing information on the calculated offset. Accordingly, the offset of the Wheatstone bridge type sensor can be rapidly and easily calculated independently from the size of a bias current, and ultimately. Furthermore, time required to measure can be reduced and thus a sensor fabrication cost can be reduced, and also, mass production can be enhanced.
