DNOIS

Package dnois provides some commonly used or basic functions and classes.

Camera

Camera(optics, sensor)

A basic camera model.

Physics

c	Convert a string or number to a floating point number, if possible.
fdc()	Returns the wavelengths of Fraunhofer's F, d and C lines.
fline([symbol, element, alone, unit])	Alias for fraunhofer_line().
fraunhofer_line([symbol, element, alone, unit])	Returns information about Fraunhofer lines.
k(wl[, n])	Alias for wave_vec().
reflect(incident, normal)	Computes direction of reflective ray given that of incident ray and normal vector:
refract()	Computes direction of refractive ray given that of incident ray, normal vector and refractive indices.
wave_vector(wl[, n])	Computes magnitude of wavelength vector:

Functions

zernike(r, theta, k)	Computes the \(k\)-th term of Zernike polynomials:
zernike_cpd(r, theta, k)	Computes the Cartesian partial derivatives of \(k\)-th term of Zernike polynomials.

Debugging

debug([on])	Switch debugging mode on or off.
debugging()	Returns whether debugging is enabled or not.

Units

convert(value, from_, to[, unit_type])	Convert a quantity with given unit from_ to that with unit to.
get_default(unit_type)	Get global default unit.
set_default(unit_type, unit)	Set global default length unit.
Unit(value[, names, module, qualname, type, ...])	Base class of all units.
Length(value[, names, module, qualname, ...])	Length units.
Angle(value[, names, module, qualname, ...])	Angle units.

Exception classes

ShapeError	Raised when the shape of a tensor is invalid for some functions.
PhysicsError	Raised when some physical assumptions are not met.

Miscellaneous
