Sentence examples for focus lengths from inspiring English sources

The phones achieve this by taking a series of images in quick succession at different focus lengths rather than replicating the light field effect captured by a Lytro camera.

To separate the effects of spin diffusion and spin relaxation, the grating decay rate is measured as a function of the grating wave vector q by changing the phase mask with different periods (d = 5, 6, 7, and 8 μm) and/or the second spherical mirror with different focus lengths (f 2 = 15.2 and 30.4 cm). Figure 2a shows the grating decay rate as a function of q 2 for two excitation powers.

Thus the projection lens was designed with focus length of 9.45 mm, F-number of 2.8 and FOV of 72.45°.

where, c f = 1 N c f and r f = 1 N r f represent the actual length of one pixel divided by the focus length.

The channel is the rigid tube of elliptic cross-section having the focus length (c=90mbox{ $mu$m}) and the eccentricity (bar{e}=0.60).

Fringe projection profilometry requires that the projection lens has super short focus length and wide field of view (FOV) as well as large projection area as possible.

The focus length of the graphene-based terahertz lens can be tunable by changing the applied electric field without change the configuration.

The back focus length tuning range is demonstrated from 35 mm to 250 mm and zoom ratio of up to seven without any mechanical moving components.

To extend the usage of the terahertz wave, we present a simple method for variable focus length terahertz wave lens based on graphene.

In this study, a statistical design of experiment (DOE) was used to optimize selected LBW parameters (laser power, welding speed and focus length).

heading angle of the vehicle ϕ v. pitch angle of onboard camera θ. actual length of one pixel divided by the focus length of onboard camera c f and r f.
