The proposed technique visualizes displacement of light deflected by ultrasound, and the use of focusing optics enables flexible settings of the virtual screen position and optical magnification.
In one version, the small camera would be built in such a way that you could adjust zoom using different focal ratios for true optical magnification.
Images recorded at high optical magnification show the particles adhering to gas bubbles individually or as aggregates.
However, the efficacy of NBI to identify an MC pattern without optical magnification has not been determined.
The size of the laser spot is approximately 2 μm with × 50 optical magnification of the attached optical microscope.
Apple's current iPhone camera uses digital zoom, but this results in far more degradation of quality versus true optical magnification like those found in DSLR telephoto lenses, and compact cameras with traditional zoom lenses.
Following examination under optical magnification, some areas, on three of the stones, were found to bear minute metal-looking remains of decorative coatings.
The sCMOS camera is coupled to a scintillator for conversion from X-ray to optical, in addition to an oil-immersion lens (Nikon) for 20× optical magnification.
Traditional visual aid devices typically utilise optical magnification to counteract the reduced visual clarity, i.e. blurred vision, by increasing the objects' perceived visual size, which can be useful.
After bracket failure, the enamel surface was examined under optical magnification (×10), and the amount of adhesive remaining on the tooth was recorded using the ARI.
The MTF (Modulation Transfer Function) of the off-axis reflective lens, with optical magnification 100×, F-number 2.5 and field of view 120°, is over 40% at 0.6 lp/mm on the image side, the distortion is less than 2%.
