3D TOF sensors contribute to touchless machinery operation and labor-saving autonomous robots

Distance image sensors S15452/S15453/S15454-01WT

Touchless operation of machinery for hygiene management, measurement tools for ensuring social distance, and labor-saving autonomous robots are becoming more common in everyday life. This trend has attracted attention to the sensor technology that makes such technologies possible.

The distance image sensor is designed to measure the distance to an object by an indirect TOF (time-of-flight) method. It can be used for people/object detection and shape recognition in various situations requiring touchless (non-contact) or labor-saving technology.

We have recently added three back-thinned sensors (64 pixels, 256 pixels, and 96 × 72 pixels) to our lineup.

We plan to further expand our sensor lineup and release module products that integrate a light source (pulsed laser diode), optical system, and integrated circuits (ASIC).

Module product / Custom product

We are planning to commercialize a distance image sensor module with a built-in back-thinned distance image sensor.

We can also provide custom products that meet customers’ requests. We accept a wide range of requests, from changes to the specifications of standard products to entirely new designs.

In addition to our own light transmitting and receiving devices, we possess various technologies including optical design, circuit design, assembly, software, and more. By combining these technologies, we can offer modules that maximize device performance.
