SensoHub has been developing a time delayed integration (TDI) sensor since 2018 and was working on applying them on satellites, the company CEO said on Friday.

TDI is an image sensor that increases light absorption in timed intervals. It is a charged couple device (CCD) which lost out against CMOS in image sensors in the consumer space.

SensoHub has developed a CCD, CMOS hybrid sensor and has been supplying them to Vieworks for image sensors used in camera modules for industrial applications.

SensoHub CEO Nam Jung-hyun said during the Advanced Semiconductor Safety Innovation Conference (ASSIC) 2024 conference, hosted by TheElec and QRT, that its industrial TDI sensor were used in inspection equipment in chip and display productions.

This experience has allowed it to secure technology that allows its TDI sensors to have fast response times, Nam said.

Based on this technology, SensoHub has been developing a TDI sensor aimed at space applications with upped reliability since 2018, the CEO said.

These sensors are aimed at small satellites that rotate low orbit with relatively less radiation exposure.

SensoHub has verified the image sensor with the Korea Aerospace Research institute and the technology was completely domestically made, Nam stressed. 

The company was part of a project that aims to shoot a satellite up into space in 2025 that uses these sensors. These sensors use organic materials but SensoHub was also developing sensors that use inorganic materials, the CEO also said.
