摘要： An image display apparatus is capable of recycling the “OFF” state light to increase the image brightness and contrast. The image display apparatus includes a light source, a spatial light modulator, a total internal reflection (TIR) prism, a projection lens set, and a reflector. The spatial light modulator selectively modulates a light beam from the light source to a first path to form a first path light beam or to a second path to form a second path light beam. The TIR prism disposed between the light source and the spatial light modulator is configured to allow the light beam to travel therethrough in a first direction and to be incident on the spatial light modulator. The projection lens set disposed between the modulator and a screen is configured to project the first path light beam to form an image on a screen. The reflector is configured to reflect the second path light beam to form a reflected light beam that is incident on the TIR prism in a second direction as a recaptured light beam. The recaptured light beam is then incident on the spatial light modulator in the first direction.

摘要： A projection system comprises a light source module and a light-guiding assembly. The light source module comprises a reflecting cover and a light source disposed in the reflecting cover to form a first beam with a first f-number. The light-guiding assembly comprises a body with an incident end and a lens disposed on the incident end. The first beam passes through the lens disposed on the incident end to form a second beam with a second f-number. The second f-number of the second beam is different from the first f-number of the first beam.

摘要： Measurement system and methods for measuring oxygenated hemoglobin saturation level are provided. Light is transmitted to test blood and a reference mirror. The reference mirror provides a first reflected light beam, and backscattered light from different depths of the test blood generates a second reflected light beam. An interfered light signal is generated by light interference of the first and second reflected light beams. According to the interfered light signal, a first light decay constant for a first light wavelength range and a second light decay constant for a second light wavelength range are obtained according to the interfered light signal. A decay ratio of the first light decay constant to the second light decay constant is obtained. Oxygenated hemoglobin saturation level of the test blood is obtained according to the decay ratio.
