摘要： A stereoscopic lens apparatus includes two optical systems disposed in parallel. The two optical systems each include a front group, a reflection unit, and a rear group that are disposed in order from an object side to an image side, and an optical axis interval between the rear groups of the two optical systems is shorter than an optical axis interval between the front groups of the two optical systems due to optical path bending by the reflection unit. The rear groups of the two optical systems each include a movable unit that can be moved. The stereoscopic lens apparatus further includes a holder integrally holding the movable units of the two optical systems, and an actuator configured to drive the holder.

摘要： The present disclosure generally relates to optical systems for surgical procedures, and more particularly, to optical relay systems for visualization systems used during ophthalmic microsurgical procedures. The optical systems described herein provide improved ergonomics for surgeons, as such systems facilitate a low-height microscope camera that enables a surgeon to see over the camera to a display screen or other monitor placed in an ergonomically advantageous position for ophthalmic procedures. Such optical systems also provide improved performance, as the total magnification of the optical head may be split between multiple lens barrels, thereby creating high resolution images that enables surgeons to see ophthalmic anatomies more clearly. Even further, such optical systems proffer improved manufacturability, with reduced weight and manufacturing cost, as the lens barrels may have fixed focal lengths for utilization with digital magnification mechanisms.

摘要： Described are embodiments of methods of obtaining three-dimensional (3D) surface data of an object scene such as an intra-oral cavity. For example, measured surfaces may include the enamel surface of teeth, the dentin substructure of teeth, gum tissue and various dental structures. The methods can also be applied in medical applications and other applications in which 3D measurement data are acquired with maneuverable 3D measurement devices. In certain embodiments, the measurement device is positioned and translated to enable 3D data to be acquired for a backbone 3D data set. Subsequent controlled motion of the measurement device enables additional 3D data to be acquired and accurately joined to the backbone 3D data set.

摘要： A plurality of viewpoint images are acquired and images for three-dimensional image display are generated without causing a reduction in polarization performance. Provided are: a first polarization means which has a first polarization region and a second polarization region that each allows different polarized light to be transmitted therethrough; a second polarization means which is made up of a third polarization region that allows only the transmitted light of either one of the first polarization region or the second polarization region to be transmitted therethrough, and a total transmission region that allows the transmitted light of the first polarization region and the second polarization region to be transmitted therethrough; an imaging element into which the transmitted light of the second polarization means is input; and an image processing unit which executes signal processing for an output signal of the imaging element. The image processing unit generates parallax information in which subject distance is reflected by applying a first viewpoint image that is based on the transmitted light of the total transmission region of the second polarization means, and a second viewpoint image that is based on the transmitted light of the third polarization region of the second polarization means, and generates a left-eye-purpose image and a right-eye-purpose image for three-dimensional image display by means of image conversion processing of the first viewpoint image for which the parallax information is applied.
