ams OSRAM TMF8820, TMF8821, and TMF8828 Multizone Time-of-Flight (ToF) Sensors come in a single modular package with associated vertical-cavity surface-emitting laser (VCSEL). These direct-time-of-flight (dToF) devices are built using a single-photon avalanche diode (SPAD) array, time-to-digital converter (TDC), and histogram technology. The sensors feature an associated vertical-cavity surface-emitting laser (VCSEL), while the high-quality lens on the SPAD supports a dynamically adjustable field of view up to 63°. The highly versatile sensors enable the detection of the target area in multiple zones with extremely precise measurement results. The sensors can also detect multiple objects per zone, allowing automated robots to gain additional sensory awareness and provide early alerts to potential obstacles.
The ams OSRAM TMF8820, TMF8821, and TMF8828 Sensors perform all raw data processing on-chip, and the devices report both distance information and confidence values through an I2C interface. Housed in a single compact modular package, the sensors support a range of demanding applications, including laser detect autofocus for mobile phone cameras, object detection and collision avoidance, presence detection, and light curtain applications for industrial safety designs.
