Numerical Focusing of a Wide Field-of-View Instrument for Monitoring the Planetary Energy Budget. Proceedings 2019, 27, 17.http://hdl.handle.net/10919/93974Wide field-of-view optical instruments based on Ritchey-Crétien telescopes have been proposed to replace narrow field-of-view scanning instruments for Earth radiation budget monitoring applications. A disadvantage of such instruments is that they are subject to significant focal plane distortion. A novel numerical focusing scheme is proposed and demonstrated using a Monte Carlo ray-trace-based simulation of the performance of a candidate instrument. Results are presented which indicate that image recovery error can be significantly reduced using the proposed algorithm.application/pdfenCreative Commons Attribution 4.0 Internationalnumerical focusingRemote sensingEarth radiation budgetMonte Carlo ray-trace methodArticle - Refereed2019-09-23https://doi.org/10.3390/proceedings2019027017
