PN_88_593.traceMany¶

raytracing.eo.PN_88_593.traceMany(self, inputRays)

This function trace each ray from a group of rays from front edge of element to the back edge. It can be either a list of Ray(), or a Rays() object: the Rays() object is an iterator and can be used like a list.

Parameters:	inputRays (list of object of Ray class) – A List of rays, each object includes two ray. The fisr is the properties of the input ray and the second is the properties of the output ray.
Returns:	rayTrace – List of Ray() (i,e. a raytrace), one for each input ray.
Return type:	object of Ray class

Examples

First, a list of 10 uniformly distributed random ray is generated and then the output of the system for the rays are calculated.

>>> from raytracing import *
>>> # M is an ABCD matrix of a lens (f=10)
>>> M= Matrix(A=1,B=0,C=-1/10,D=1,physicalLength=2,label='Lens')
>>> # inputRays is a group of random rays with uniform distribution at center
>>> nRays = 10
>>> inputRays = RandomUniformRays(yMax=0, maxCount=nRays)
>>> Tr=M.traceMany(inputRays)
>>> #index[0] of the first object in the list is the first input
>>> print('The properties of the first input ray:\n', Tr[0][0])
The properties of the first input ray:
 y =  0.000
theta =  0.153
z = 0.000

>>> #index[1] of the first object in the list is the first output
>>> print('The properties of the first output ray:\n', Tr[0][1])
The properties of the first output ray:
 y =  0.000
theta =  0.153
z = 2.000
