Bare cavity unstable axisymmetric resonators with magnifications that are linear functions of the radial coordinate are investigated. Some properties similar to those of ordinary resonators are found. The geometrical theory predicts modes and eigenvalues in reasonable agreement with physical optics results. ...
Magnification of Unstable ResonatorsFor the analysis of an unstable resonator, its round-trip magnification M is an important parameter. Essentially, it tells how much the transverse position of a beam on a resonator mirror increases within one resonator round trip. For certain common unstable ...
Talking about planets. Some nights (few..) binoviewing has been only a hassle and lost of time. Other nights (also few...) they have offered nicer views than mono. Detail easier and faster to see, higher "apparent" magnification... Maybe it has to do with seeing/transparency, with...
A second flat mirror in the optical path is dichroic to pass visible light from the illuminated sample to the CCD camera. The on-screen captured image magnification is about 50×. The LTB laser control firmware allows attenuation of the output energy in a step-wise manner with 250 steps in...

Said image is formed on the detectors 7-1, 7-2 by objective lenses 6-1, 6-2 of about 1 times magnification via the mirror 5-1, 5-2, whereby the image is detected with good contrast. The longitudinal direction of the detectors 7-1, 7-2 is set in the direction perpendicular to ...
is utilized in conjunction with the spinner, the magnitude of the bow in the image plane will be influenced by the angular magnification properties of the lens. If the lens is of a telephoto design, there will be an increase in bow, whereas, the reverse is true for a wide angle design....
Besides the image magnification issue commented before, the hyperbola eccentricity would produce a significant secondary mirror width, increasing the complexity of the geometry and the shadow losses on the primary field of heliostats. Therefore, this paper proposes the modification of the secondary ...
The introduction of the above values for the abcd matrix in Eq. (13) enables us to obtain Eq. (11). For any transfer matrix, elements A and D describe the lateral magnification while C depicts the focal length, whereas the device’s optical thickness is given by B = L/n, where L ...
37, for each mechanical configuration of the calibration equipment 16, 177, and 226 (e.g. physical position or optical magnification setting), the calibration method is as follows: At step 241, a virtual calibration pattern is projected in the field of view of a desired object. At step 242...
