Rohm Laserdiode for Gesture and Depth recognition RLD8 and RLD9 Series

In recent years motion sensing has garnered increased attention, with motion sensor modules integrated into gaming devices for gesture control, providing a new type of user interface. For example, optical modules using infrared laser diodes and infrared LEDs are being increasingly adopted as input devices in PCs and portable equipment.
The RLD8 and RLD9 series of laser diodes, designed for use as light sources for “structured Light” and infrared projector with MEMS. The series of Patterns/pixels are projected upon an object, the deformation of pattern is detected by camera/sensors and used to calculate depth/surface information ( 3D motion sensor)

Infrared high power laser diodes are expected to be adopted in a wide variety of applications, including motion sensors. These lasers emit high-power infrared radiation and detect infrared rays reflected by an object through a receiving block, making it possible to detect the motion and position of an object with a high degree of accuracy.
