What is LiDAR





Currently, to ensure safe and comfortable driving, the development of ADAS (Advanced Driving Assistance System) is progressing. This function grasps information about the vehicle's surroundings using sensors, cameras, and radars installed throughout the vehicle and assists the driver in driving. Some functions have already been adopted in vehicles.

One of the sensing technologies of ADAS is LiDAR, which uses laser light to judge and measure the distance between an object and its shape. This technology can measure the distance and shape of people and objects in three dimensions with high accuracy, so there are high expectations for realizing full-scale autonomous driving technology level 3 and above using LiDAR technology.


There are various types of LiDAR, such as a mechanical rotation type equipped with a motor that detects 360° in all directions, a solid-state type that is miniaturized by eliminating the motor drive unit, and a MEMS type that uses an electromagnetic MEMS mirror.

Each method has advantages and disadvantages, but the mechanical rotation type is adopted in many vehicles due to its high performance and reliability.

Our proposal for LiDAR

The gel-like material "αGEL (Alpha GEL)" developed independently by Taica, which we handle, has excellent shock absorption and various excellent performance, such as vibration prevention, vibration control, heat dissipation, optical bonding, waterproofing, and dustproofing.




The high shock absorption property can solve the effects of vibration and micro-vibration caused by the miniaturization of modules, and the high heat dissipation property protects semiconductors that are easily affected by high heat from heat and can also be used as a heat dissipation measure for IC chips that generate a lot of heat. In addition, because it is a durable and long-lasting material, it eliminates the hassle of frequent maintenance and replacement like acrylic and rubber products.

By using it as a shock-absorbing material for laser light sources and light-receiving devices, it is possible to compensate for and improve the coherence that limits the performance of LiDAR. Similarly, by using it to dissipate heat from laser light sources, it is possible to reduce the impact of heat on the laser wavelength and light output.
