Hamamatsu Photonics, a global leader in photonics technology, has successfully designed and developed a new near-infrared area image sensor by leveraging its unique circuit design technology. This groundbreaking sensor offers remarkable features, including enhanced speed and a significantly widened dynamic range, doubling the capabilities when compared to existing products designed for hyperspectral cameras.
Referred to as the G16564-0808T, this innovative sensor is crafted from a combination of indium (In), gallium (Ga), and arsenic (As) materials. Users are granted the flexibility to select their desired signal read-out wavelength, making it an exceptionally versatile solution for a broad spectrum of applications, encompassing the imaging and measurement of objects with diverse material compositions and dimensions. This extends to fields such as plastic recycling, and quality control in the pharmaceutical and food industries, which includes plant-based alternatives.
Main Features
- Up to two times increase in readout speed and dynamic range: The electrical signal readout speed has been increased up to about 2 times by using a decoder circuit in the readout circuit. The dynamic range was also improved up to about 2 times by using a depression-type signal processing circuit that lowers the threshold voltage to improve electrical current flow.
- Multi-line readout: A multi-line readout function was added to the circuit to read signals at specific light wavelengths. The readout speed can be boosted even further by focusing the readout on just near-infrared wavelengths that are easily reflected by the target object for screening.
