Exhibit Report: chikumoto Laboratory Participates in EXPO 2025 TEAM EXPO Pavilion

We are pleased to report that the chikumoto Laboratory of the Institute of Laser Engineering, Osaka University exhibited a booth and gave a stage presentation at the TEAM EXPO Pavilion of the Osaka Kansai Expo (EXPO 2025), held on May 18, 2025, at Yumeshima.

This exhibition was part of the TEAM EXPO Co-Creation Challenge, under the theme:
“Creating a Super-Smart Future Society That Is Safe and Inspiring Through Aerial Displays and Visual Effects.”
The team participated under the name “Tsukumoto Laboratory, Institute of Laser Engineering, Osaka University,” and the presentation took place at Unit TE1, an outdoor exhibition space facing the courtyard of the Future Life Village pavilion cluster.

The booth featured a 32-inch monitor embedded in a custom-designed cardboard fixture, which played a video introducing the project theme. In addition, the team conducted three types of laser-based aerial display demonstrations, using a beam-scanning laser projector, an aerial screen, and a drone.

A key highlight was a demonstration in which a single projector displayed images on multiple screens arranged in a row, showcasing the focus-free capability of the beam-scanning projection method, which enables flexible image projection without the need for refocusing.

The team also demonstrated 3D imaging using LiDAR, employing the same visible-light laser source used in the projector. The exhibit proposed the integration of projectors and LiDAR into future IoT lighting stations, maximizing the potential of laser-based aerial displays and the versatility of visible-light laser scanning technologies.
