- We propose an optical system employing a compound parabolic concentrator for near infrared spectroscope in noninvasive blood components testing. A truncated two-stage compound parabolic concentrator system is designed, which consists of a normal first-stage compound parabolic concentrator and a truncated second-stage compound parabolic concentrator. Using advanced ray tracing technique, the optical efficiencies of truncated two-stage compound parabolic concentrator system, ellipsoidal mirror system and non-optical-focusing mirror system are calculated to be 25.4%, 22.4% and 4.0%, respectively. Furthermore, the total length of truncated two-stage compound parabolic concentrator is only about 68 mm while the ellipsoidal mirror is 110 mm. It indicates that the truncated two-stage compound parabolic concentrator system enhances the ability of concentrating human diffuse transmission light, and it is a benefit to improve signal-to-noise ratio of noninvasive biochemical analysis system efficiently. Due to the advantage of small size, it tends to achieve a miniature instrument.
