Lentil 0.8.3

Heart-healthy physical optics

Lentil is a Python library for modeling the imaging chain of an optical system. It was originally developed at NASA’s Jet Propulsion Lab by the Wavefront Sensing and Control group (383E) to provide an easy to use framework for simulating point spread functions of segmented aperture telescopes.

Lentil provides classes for representing optical elements with a simple interface for including effects like wavefront error, radiometric properties, and various noise and aberration sources. Lentil also provides numerical methods for performing Fraunhofer (far-field) diffraction calculations. The collection of classes provided by Lentil can be used to simulate imagery for a wide variety of optical systems.

Lentil is still under active development and new features continue to be added. Until Lentil reaches version 1.0, the API is not guaranteed to be stable, but changes breaking backwards compatibility will be noted.
