摘要: 本論文中,我們研究一頭戴顯示器,其工作範圍涵蓋可見光波段與紅外 光波段。由於可見光與紅外光的波長相差甚大,產生了相當大的色差問題, 為了克服此色差問題, 我們將整個系統都使用了反射鏡。除此之外, 我們 使用了自由曲面來克服球差與慧差等像差, 降低系統鏡片數。這些自由曲 面鏡的功能是將微顯示器所產生的內容, 放大後投射至人眼。當使用0.61 吋的微顯示器時,將產生對角線方向的視角30 度,當出瞳大小為8 釐米時, 產生出的f/#為3.75。本系統的適眼距為15 釐米。
It is a challenge to design a head-mounted display (HMD) that covers both visible and infrared rays. Since the HMD system covers such a broad spectral band, large color aberrations will be induced. In order to eliminate these large aberrations, a mirror system is adopted that will create a no color aberration system. We also use two freeform mirrors (FFMs) to reduce residual aberrations such as spherical aberrations and coma. The FFMs serve as the near-eye viewing optics that magnifies the image which is displayed through a microdisplay. Based on a 0.61 in. microdisplay, the HMD system demonstrates a diagonal field of view (FOV) of 30 degree and an f/# of 3.75, with an exit pupil diameter of 8 mm and eye clearance of 15mm.
