differt.em.length_to_delay

length_to_delay(length, speed=299792458.0)

Compute the delay, in seconds, corresponding to the length.

Parameters:

• length (Float[ArrayLike, '*#batch']) – Input length (in meters).

• speed (Float[ArrayLike, '*#batch']) – Speed (in m/s). Defaults to the speed of light in vacuum.

Return type:

Float[Array, '*batch']

Returns:

The path delay.

Examples

The following example shows how to compute a delay from a length.

>>> from differt.em import c
>>> from differt.em import (
...     length_to_delay,
... )
>>>
>>> length = jnp.array([1.0, 2.0, 4.0])
>>> length_to_delay(length) * c
Array([1., 2., 4.], dtype=float32)
>>> length_to_delay(length, speed=2.0)
Array([0.5, 1. , 2. ], dtype=float32)
