Once you know the FOV, you can use the following equation.

只要你知悉FOV, 你就能应用下列的方程式.

互联网

FOV: Allows you to customise the amplitude of your field of view.

视场: 让您自选振幅你的视野.

互联网

The selecting rules are mainly position resolution, receiving FOV, sensitivity.

选择依据主要是:位置分辨率, 接收视场角和灵敏度.

互联网

The SIR increased with Fov, flip angle, matrix, angle of slice position.

结果:随着翻转角、视野 、 矩阵 、 层面定位角度的增大,SIR值增大.

In an array laser warning, two adjacent photodiode field - of - views ( FOV ) overlap and form overlapped FOVs.

在阵列式激光报警器中, 相邻两 光电二极管 视场重叠,形成重叠视场.
