 note = {正方形の卓を囲んで 4 人で作業を行う際，空中像を各ユーザに割り当てることで実物体のみでは実現しえない作業環境を構築できる．しかし，空中像を結像する素子である再帰透過光学素子を卓面として卓を囲む四方向全てに空中像を表示した場合，迷光と呼ばれる不要な光が目立ってしまい，空中像の鑑賞が妨げられるという問題がある．本研究では偏光板と視界制御フィルムを用いることによって迷光を抑制し，卓を囲む 4 人のユーザが両面空中像を鑑賞できる光学系を提案する．迷光の一つである透過光を効果的に低減する複数の素子について，低減の様子を比較した．さらに，提案光学系の設計の際に考慮する必要があるパラメータとその制約を求めた．, When four users work together around a square table, distributing mid-air images to each of them can build a new working environment which cannot be realized only with real objects. However, there is a problem that bright stray light confuses mid-air images and interferes with the user’s experience if dual Slit Mirror Arrays (dual SMAs), which are one of the devices of forming mid-air images, are used as a table’s surface and display mid-air images in four directions around them. This paper proposes an optical system that displays dual-sided mid-air images to each of four users with less stray light by placing polarizers and view control films (VCFs). We examined the films to be used in our system by showing how stray light is suppressed. In addition, we showed constraints that we need to take into account when implementing our system.},
