High-speed terahertz reflection three-dimensional imaging for nondestructive evaluation.
We demonstrate high-speed terahertz (THz) reflection three-dimensional (3D) imaging based on electronically controlled optical sampling (ECOPS). ECOPS enables scanning of an axial range of 9 mm in free space at 1 kHz. It takes 80 s to scan a transverse range of 100 mm × 100 mm along a zigzag trajectory that consists of 200 lines using translation stages. To show applicability of the imaging sys...
متن کاملHigh-speed three-dimensional imaging of the pulmonary alveoli
Investigating the structure and function of pulmonary alveoli in vivo is crucial for understanding the normal and diseased lung. In particular, understanding the three-dimensional geometry and relationship of the terminal alveoli to their neighboring alveoli, alveolar ducts and acini during respiration would be a major advance. However, the lung is an inherently difficult organ to image in vivo...
متن کاملHigh-speed terahertz reflection three-dimensional imaging using beam steering.
High-speed terahertz (THz) reflection three-dimensional (3D) imaging is demonstrated using electronically-controlled optical sampling (ECOPS) and beam steering. ECOPS measurement is used for scanning an axial range of 7.8 mm in free space at 1 kHz scan rate while a transverse range of 100 × 100 mm(2) is scanned using beam steering instead of moving an imaging target. Telecentric f-θ lenses with...
متن کاملHigh-speed AFM imaging.
Proteins are dynamic in nature and function at the single molecule level. To achieve a straightforward and in-depth understanding of their underlying functional mechanism, we need to directly observe protein molecules at work at high resolution, without the use of protein-attached markers. To realize such objectives, high-speed atomic force microscopy (HS-AFM) has been developed and recently it...
متن کاملCompressive high-speed stereo imaging.
A compressive high-speed stereo imaging system is reported. The system is capable of reconstructing 3D videos at a frame rate 10 times higher than the sampling rate of the imaging sensors. An asymmetric configuration of stereo imaging system has been implemented by including a high-speed spatial modulator in one of the binocular views, and leaving the other view unchanged. We have developed a t...
