FAQs
  • What is the difference between focal length and focal distance of a lense?
    Focal distance refers to the distance from the front of the lens to the beam crossing point (see figure).   To define the focal length, the lens is replaced by a line, AB. The positon of the vertical line is such that the two parallel beams are deflected, as shown in the figure, so that the two beams cross. The distance measured from this line AB to the focal point is referred to as the focal length of the lens. For the case of a thin lens (thickness of the lens/focal length is small), the value of focal length and focal distance are almost the same. For the case of a thick lens, the location of the line AB will be noticeably different from the front of the lens. Hence, the focal length and focal distance will differ.
  • What is the relationship between the velocity component measured and the frequency (Doppler) of the signal?
    The component of velocity that lies in the plane of the beams and normal to the bisector of the two laser beams of a dual-beam system is measured by an LDV system. From the following figure, the component of velocity measured is uy. If 2kappa is the angle between the two beams, the fringe spacing, df for the dual beam LDV system is:df = lambda / (2 sin kappa)where lambda is the wavelength of light.If fD is the Doppler frequency of the signal generated by the passage of a particle with velocity u (see figure) through the measuring volume:fD = uy / df Hence, the frequency of the Doppler signal is proportional to velocity.
