可攜式多頻段刺激光及紅外線照明之瞳孔偵測裝置

Abstract

本發明提供一種可攜式多頻段刺激光及紅外線照明之瞳孔偵測裝置，包含至少一瞳孔偵測模組以偵測一使用者的瞳孔變化，每一瞳孔偵測模組包括：一照明光源，其係發出非可見光；一刺激光源，其係發出可見光；至少一分光元件，對應照明光源、刺激光源及使用者之一眼睛，在分光元件、照明光源及眼睛之間形成一第一光路徑，在分光元件、刺激光源及眼睛之間形成一第二光路徑；一透鏡，對應分光元件，接收分光元件送出之非可見光並形成眼睛的成像；以及一成像元件，接收透鏡上之眼睛的成像。 The present invention provides a portable pupil detecting device of multi-band stimulating light and infrared ray’s illumination, which comprises at least a pupil detecting module for detecting variation of a user’s pupil. Each pupil detecting module comprises an illuminated light source for radiating visible light; a stimulated light source for radiating invisible light; at least a beamsplitter corresponding to the illuminated light source, the stimulated light source and a user’s eye, forming a first optical path between the beamsplitter, illuminated light source and the eye and a second optical path between the beamsplitter, stimulated light source and the eye; a lens corresponding to the beamsplitter, receiving invisible light from the beamsplitter and forming an imaging of the eye; and an imaging element for receiving the imaging from the lens.
