M inverted telescope compression ratio on the inclination of the ordinary light. laser modulation laser is the modulation of the laser as a carrier to carry low-frequency signal modulation and external modulation in the laser modulation can be divided into two categories. here mainly to the external modulation. instantaneous light field in the laser modulation mode laser expressions instantaneous light intensity modulated signal is a sinusoidal signal: the laser amplitude modulation of the expression is a typical electro-optical intensity modulation device schematic diagram of a uniaxial electro-optic crystal placed in it by the two cross-polarizers their polarizer pass direction of vibration parallel with the x, y-axis, respectively.Haituo  green laser pointer  company concentrates on project management. 2. set up a time added to the voltage on the electro-optic crystal V, incident to the crystal in the x direction, linearly polarized laser electric vector amplitude is E, then: through the crystal along the fast axis x 'and the slow axis y' electric vector amplitude becomes the difference between the second line of the direction of vibration of polarized light see through the amplitude of the light through vibration direction and the y-axis parallel to the polarizer polarizer draw II of 0? V- part of the curve and light stress on the situation. click at the midpoint in the curve, usually in the modulation of the crystal plus the DC bias Vπ to complete the phase modulation device schematic electric field is applied, the vibration direction of the crystal y 'axis parallel to the light through the length l crystal, the phase increase added on the crystal electric field of sinusoidal modulation of light in the input side of the crystal (z = 0) at the field vector size in the crystal output face (z = l) of the field vector size can be written as in FigureHaituo  green laser pointer  company focuses on the technical service quality of application implementation. (4-23) phase modulation device Schematic diagram of a mechanical deflection vibration of the rotation of the mirror or reflected from a prism or mirror to achieve beam scanning. mechanical deflection mirror or multi-surface reflector rotation or vibration of the mirror to achieve beam scanning. mechanical deflection vibration of the rotation of the mirror or reflected from a prism or mirror to achieve beam scanning 4.5.2 electro-optical deflection of a using Pockels effect in electric field is applied to change the refractive index of the crystal electro-optic crystal, the beam deflection.Haituo  green laser pointer  company implements the project of enterprise administration in full. Pockels effect, an applied electric field changes the refractive index of the crystal so that the beam deflection in the electro-optic crystal. the actual electro-optic crystal deflector consists of two crystal prism (such as prism) of the composition shown in the electro-optic crystal deflector by the two crystal prism, such as the KDP prism of composition, as shown in Figure -24. prism composed, as shown in Figure 4 - shown in two if the laser is perpendicular to a right angle surface reach all parts shown in Figure -24 following the following straight, if the laser is vertical at right angles to the surface to reach all parts shown in Figure 4 - straight, if the laser is vertical at right angles to the surface shines Figure prism.
