Abstract: The extragalactic background light (EBL) contains all the radiation emitted by nuclear and accretion processes in stars and compact objects since the epoch of recombination. Measuring the EBL density directly is challenging. However, gamma-ray astronomy provides an alternative approach to indirectly studying the EBL through the observation of gamma-ray absorption in the spectra of distant blazars. The Large High Altitude Air Shower Observatory (LHAASO), with its unique capabilities --- near full duty cycle, wide field of view, and high sensitivity -- is exceptionally well-suited for exploring the EBL, particularly in the near to mid-infrared region (wavelengths of 1 to 100 micrometers). In this presentation, we will discuss the methods we employed for data analysis and share our preliminary findings.
