Abstract: In Today's World, There Is A Need Of Verge Of Significant Transformation In Electrical Power System. The Vehicle-To-Gird (V2G) Concept Optimizes This Transformation. The PEV Typically Has A Higher Capacity Energy Storage System (ESS). Each PEV Stores Approximately 5-40kwh Of Energy. This Energy Can Be Transferred To The Vehicle-To-Grid (V2G), Vehicle-To-Home (V2H) And Vehicle-To-Building (V2B) As Most Of The Time The Vehicle Is Kept In Parking As Idle. Plug In Hybrid Electric Vehicles Have Vast Scope And Capabilities Of Energy Storage. This Feature Of EV Can Be Utilized For Energy Storage Along With Distribute/Sell It During Peak Demand. In [4] The Various Features Of V2G, Its Applications, Advantages Along With Its Challenges To Implement.......

Abstract: The Point Spread Function (PSF) is a fundamental concept in the field of optics, describing the response of an optical system to a point source of light. This study aims to investigate the effects of central circular obscuration on the intensity characteristics of the PSF. The research employs theoretical analysis, to comprehensively explore how the size and position of the obscuration influence the intensity distribution within the PSF. This study also focuses on investigating the impact of central circular obscuration on the FWHM of the PSF.

Keywords: Point Spread Function, PSF intensity, central circular obscuration, optical systems, Full Width at Half Maximum (FWHM), image resolution.
