mx::AO::analysis::pywfsUnmod< realT, iosT > Struct Template Reference

template<typename realT, typename iosT = std::ostream>
struct mx::AO::analysis::pywfsUnmod< realT, iosT >

The unmodulated pyramid wavefront sensor sensitivity function.

Provides the \( \beta_p \) parameter of Guyon, 2005 [9] for the unmodulated PyWFS.

Template Parameters

realT	is the floating point type used for calculations
iosT	is an output stream type with operator << defined (default is std::ostream)

beta_p()

template<typename realT , typename iosT = std::ostream>

virtual realT mx::AO::analysis::pywfsUnmod< realT, iosT >::beta_p ( int  m, int  n, realT  D, realT  d, realT  r0  )

inlinevirtual

Get the photon noise sensitivity at a spatial frequency.

The sensitivity of the unmodulated PyWFS is \( \sqrt{2} \) at all k.

Returns

the sensitivity to photon noise parameter

Parameters

[in]	m	the spatial frequency index for u (not used by this WFS)
[in]	n	the spatial frequency index for v (not used by this WFS)
[in]	D	the telescope diameter (not used by this WFS)
[in]	d	the sub-ap spacing (not used by this WFS)
[in]	r0	Fried's parameter (not used by this WFS)

Reimplemented from mx::AO::analysis::wfs< realT, std::ostream >.

beta_r()

template<typename realT , typename iosT = std::ostream>

virtual realT mx::AO::analysis::pywfsUnmod< realT, iosT >::beta_r ( int  m, int  n, realT  D, realT  d, realT  r0  )

inlinevirtual

Get the read noise sensitivity at a spatial frequency.

Here we assume that beta_r is the same as beta_p.

Returns

the sensitivity to read noise parameter

Parameters

[in]	m	the spatial frequency index for u (not used by this WFS)
[in]	n	the spatial frequency index for v (not used by this WFS)
[in]	D	the telescope diameter (not used by this WFS)
[in]	d	the sub-ap spacing (not used by this WFS)
[in]	r0	Fried's parameter (not used by this WFS)
