<p>An ovulatory phase deciding device and a portable wireless communication terminal using the device are provided to realize the crystal of user as an image from light reflected by the user's secretion crystal, thereby being particularly useful for a female user. A wave guide(110) consists of an upper side(110a) exposed to a user, a lower side(110b) opposing the upper side, and the first and second sides(111,112) opposing each other as being positioned between the upper and lower sides. A light source(120) emits light to the first side of the wave guide. A lens system(130) and an image sensor(140) form the user's secretion crystal as an image from light reflected by the user's secretion crystal on the upper side of the wave guide.</p> |
