The use of laser telemeter leads also to the increase of accuracy which permits continuous measurement and maintenance of the distance between spectral source of emission and spectrometer, with the same telemeter being possible to centre the optical axis
of spectrometer on the maximum spectral emission zone.
Also, if the camera optical axis
is perpendicular to the marker direction, virtual objects are chattered because of problems caused by formula for digital image processing.
instant position of the characteristic point relative to the intersection of the optical axis
of the sensor with the characteristic point plane [x.
Highly reliable sleeve mechanism enables connection of an objective lens unit and prism unit to minimise optical axis
The approach, which makes it possible to consider the current orientation of the optical axis
of mobile telecamera, is proposed in the paper (Murao et al.
We could not place the optical axis
precisely in the center of the Digital ELPH yet we knew we had to find a way to incorporate the ELPH models' key motif without sacrificing the camera's sense of balance," Omino revealed.
The emergent laser beam has to remain parallel to the optical axis
The unit detects and calculates a range and direction of the impulse sound source; slews the camera to align its optical axis
with a direction of the impulse sound; determines whether the impulse sound was a gunshot; records images of the source area; and alerts neighboring units to initiate recording of images.
Beyond this lens there is on the optical axis
focal point D as the common point of the lens K and the objective O1.
These lightweight lenses have external exit pupils and can be used to select arbitrary focal length, match spot size to detector size, align a laser beam to the axis of a lens assembly and accurately collimate light exiting an optical fiber in a parallel direction to the optical axis
The system delivers precise, reliable optical axis
alignment, and it is easy to operate.
This new invention describes a method for uniquely and unambiguously aligning a patient's visual line of sight to the optical axis
of an ophthalmic instrument such as may be used in laser surgery or diagnostics.
