New Holocoder technology delivers 2.5x more light to image sensors by sorting wavelengths without absorption.
Metalenz has acquired Israeli startup PxE Imaging, gaining access to Holocoder technology. This system replaces the standard Bayer color filter found on traditional digital image sensors. While a Bayer filter absorbs approximately 60% of incoming light to reconstruct color, the Holocoder layer sits on the sensor and bends light rather than absorbing it. This process increases the light delivered to a standard sensor by 2.5x, improving performance in both dark and bright scenes. The technology harnesses light waves to physically decode wavelength and depth simultaneously, allowing a single camera to capture color and depth information in one image. Metalenz plans to integrate these capabilities into its metasurface optics, which are ultra-thin lenses printed like semiconductor wafers. This hardware-based approach aims to provide richer data for AI models and machine vision without the heavy computational demands or information loss associated with software-only image enhancement.
Photographers and mobile content creators may soon see a significant leap in low-light performance as hardware replaces light-absorbing filters. This shift allows for the simultaneous capture of depth and color data without increasing manufacturing complexity or processing power.
