We are developing a new wide-field mosaic CMOS camera, Tomo-e Gozen, for the 105-cm Kiso Schmidt Telescope at Kiso Observatory, the University of Tokyo. Tomo-e Gozen is composed of four individual camera modules, each of which has 21 CMOS image sensors. Equipped with the 84 CMOS image sensors in total, Tomo-e Gozen is able to monitor a sky of about 20 sq-degree at up to 2 Hz. The limiting magnitude for stars is about 18.5 mag. Frame rates faster than 2 Hz are available by narrowing the field of view. Tomo-e Gozen is expected to show high performances in detecting tiny space debris and deriving the motion of space debris. The development of the first camera module Q1 was completed in February, 2018. In the experimental observations, the camera was successfully operated with the 21 CMOS image sensors. Currently, a high-cadence wide-area survey is in operation. We'll present some observations of near earth asteroids and artificial objects with Tomo-e Gozen, and discuss possible contributions of Tomo-e Gozen to the surveillance and tracking of space debris.
