NettetVisit our new website. Linear array sensors consist of a linear array of integrating photosensing pixels which measure incident light over a user-defined exposure time and generate a voltage or digital output which represents the light exposure at each pixel. The sensors are available in a variety of lengths and pixel resolutions. Nettet22. jan. 2024 · A low-cost Photoacoustic Computed Tomography (PACT) system consisting of 16 single-element transducers has been developed. Our design proposes a fast rotating mechanism of 360° rotation around the imaging target, generating comparable images to those produced by large-number-element (e.g., 512, 1024, etc.) …
