The incident angle can also be altered to increase the data base.

A small beam of light that can be varied in width, height, incident angle, orientation and colour, is passed over the eye.

Under these conditions, the intensity of the reflected light is markedly reduced at a specific incident angle, producing a sharp "shadow".

A computer-driven rotary table varies the incident angle of the laser.

Thus unless the incident angle is 90 the field lines will have a break at the boundary of two dielectrics.

The delays are closely related to the incident angle and the geometry of the sensor array.

Given the geometry of the array, the delays or phase differences can be used to estimate the incident angle.

As we performed the analysis we looked at different incident angles.

We looked at incident angles varying from 10 degrees, 13 and 16 degrees, again, trying to bound our analysis.

Refracted X-rays within this range will be reflected depending on the incident angle.
