A display apparatus including a volume grating-based combiner is disclosed. The display apparatus includes: an image providing device; and a combiner, wherein the combiner includes a plurality of volume gratings configured to diffract light containing an image, which is emitted from the image providing device, each volume grating has a first surface and a second surface facing each other, and each volume grating is further configured to diffract light incident on the first surface and transmit therethrough light incident on the second surface without diffraction.

Display apparatus including volume grating based combiner

A joint apparatus for a robot includes a housing, a bearing including an inner ring and an outer ring contacting the housing, a rotating member contacting the inner ring of the bearing, and a driving apparatus configured to rotate the rotating member, where the first housing includes a first support region configured to support a front surface of the outer ring and a first fastening region extending rearward from the first support region and on which a first thread is formed, the sounding housing includes a second support region configured to support a rear surface of the outer ring and a second fastening region extending forward from the second support region and on which a second thread is formed, and the second thread is configured to engage the first thread.

Joint apparatus for robot

A vehicle for uneven terrain includes a main frame; a front wheel assembly disposed in front of the main frame with a front wheel; a rear wheel assembly disposed behind the main frame with a rear wheel; a wheelbase adjuster configured to adjust a wheelbase between the front wheel and the rear wheel; a first side wheel assembly disposed on one side of the main frame with a first side wheel; a second side wheel assembly disposed on another side of the main frame with a second side wheel; a front wheel torque transmitter configured to interlock vertical movements of the front wheel and the first side wheel; a rear wheel torque transmitter configured to interlock vertical movements of the rear wheel and the second side wheel; and a stabilizer configured to support the first side wheel assembly and the second side wheel assembly.

Vehicle for uneven terrain

Provided are a laser speckle contrast imaging method, a laser speckle contrast imaging system, and an apparatus which includes the laser speckle contrast imaging system. The laser speckle contrast imaging system includes a laser light source configured to irradiate laser beams toward a subject, the laser beams having a plurality of wavelength bands and different surface transmittances with respect to the subject. An imaging unit is configured to acquire speckle images by capturing images of speckles by using an image sensor, the speckles being formed when the irradiated laser beams are scattered from the subject. A signal processor is configured to convert the acquired speckle images into speckle contrast images and to acquire a compensated speckle contrast image by compensating for a change caused by a movement of the subject.
