The TMF8821 is a direct time-of-flight (dToF) sensor in a single modular package with associated VCSEL. The dToF device is based on SPAD, TDC and histogram technology and achieves 5000 mm detection range. Due to its lens on the SPAD, it supports 3x3, 4x4 and 3x6 multizone output data and a wide, dynamically adjustable, field of view. A multi-lens-array (MLA) inside the package above the VCSEL widens up the FoI (field of illumination). All processing of the raw data is performed on-chip and the TMF8821 provides distance information together with confidence values on its I2C interface.

The TMF8801 is a true direct time-of-flight (ToF) sensor system in a single modular package which offers highly accurate depth accuracy detection through a sub-nanosecond light pulse and an antialiasing “stop-watch” method to measure round-trip time of pulse. It provides single zone detection of an object irrespective of the color, reflectivity and texture of the object. The single module with VCSEL emitter offers high dynamic range and detection sensing measurements from 2 – 250 cm distances. The device utilizes highly sensitive SPAD detection with fast compact time-to digital converters to make highly accurate distance measurements within ±5% and is capable of operation in dark environments and in the presence of sunlight. A built-in histogram is featured to detect cover glass and reports an object distances operating with the highest SNR while compensating for dirt and smudges contaminants on a products cover glass to produce artifact free measurement. The histogram delivers dynamic cover glass calibration and crosstalk compensation and background light noise is minimized through on-chip sunlight rejection filters. Data output is through a 1.8V I²C fast-mode communications interface and an integrated micro controller is featured with all algorithms included on-chip with no need for external optics.

2.2 MP NIR enhanced global shutter image sensor designed for 2D and 3D consumer and industrial machine vision applications. Due to its small size, configurability and high sensitivity both in visual as well as NIR, the Mira220 is well suited for 2D and 3D applications, which include Active Stereo Vision, Structured Light Vision for Robotics and AR/VR. 

BELAGO1.1 is a proprietary infrared dot-pattern illuminator for stereoscopic imaging and structured light platforms with eye-safety feature. It produces a focus-free, high-contrast dot pattern that algorithms can use to address low-texture situations and achieve high-accuracy depth maps. An additional benefit of the dot pattern is a reduction of the computational load required to perform the depth calculation.The BELAGO1.1 dot-pattern illuminator is provided in a miniature package that is compatible with standard lead-free reflow processes. As such, it can be successfully used onboard of a great variety of 3D sensing platforms, from mobile to IoT to robotics, both for stereoscopic imaging and structured light. BELAGO1.1 emitters project 5k dots, focus-free, in a random pattern at 940nm.

The TMD3725 features advanced proximity measurement, color sense (RGBC+IR), and digital ambient light sensing (ALS). The package has been designed to accommodate a “single hole” aperture approach. The slim module incorporates an IR LED and factory calibrated LED driver. The proximity detection feature provides object detection (e.g. mobile device screen to user’s ear) by photodiode detection of reflected IR energy (sourced by the integrated LED). Detect/release events are interrupt driven, and occur when proximity result crosses upper and/or lower threshold settings. The proximity engine features offset adjustment registers to compensate for unwanted IR energy reflection at the sensor. Proximity results are further improved by automatic ambient light subtraction. The ALS detection feature provides photopic light intensity data. The color photodiodes have UV and IR blocking filters and converts photodiode current into dedicated integrating data converters producing 16-bit data. This digital output can be interfaced with a microprocessor where illuminance and color temperature can be calculated to control a displays backlight and chromaticity.
