Fabry - Perot Interferometer
CCD Based
Computer interfaced Fabry-Perot interferometer (Model No:HO-ED-INT-10A) is similar to projection type (model no:HO-ED-INT-10), apart from the fact that in this case, the interference pattern is captured by a CCD sensor and displayed on a computer monitor. The advantage of computer interface is that the pattern can be saved for future analysis. In addition, measurements can be taken directly from the monitor by using the software module provided.
In the etalon, distance between partially reflecting mirrors can be precisely varied in microns. One of the beam splitters can be kinematically adjusted for initial settings.
Experiment:
To find the wavelength of monochromatic light
The wavelength of laser is calculated by,
λ = ( 2d / N ) Δ
where ‘d’ is the change in position that occurs for ‘N’ fringes to pass and Δ is the calibration constant of the micrometer
To determine the spacing between the plates of fabry perot etalon from the fringe Pattern
The Spacing of the Etalon is given by,
t = nD2λ / χn2
where n is the order, ‘D ’ is the distance between the etalon and the screen, ‘λ’ is the wavelength of light used.
χn2 = χm+n2 - χm2
χm+n2 is the square of the radius of (m+n)th ring and χm2 that of mth ring.
To find the finesse and free spectral range (FSR) of etalon from the fringe calibration at different cavity thickness
The Free Spectral Range of the Etalon is given by,
FSR = c / 2t,
Where c is the speed of light in air and t is the spacing of the Etalon
The finesse is a measure of the interferometer's ability to resolve closely spaced spectral lines.
The finesse F is defined by the following equation.
F = π √R / ( 1-R )
Where, R is the reflectivity of surfaces
