Figure 2
From: Non-invasive 3D and 360° optical imaging of micro-particles
Particle imaging with a low-cost assembly for enhanced contrast and surface definition. Images in this figure do not constitute a focus-stack, and are snapshots cropped from larger field of view images (1.7 × 1.42 mm2). (a and b) Taurine crystals (360 and 850 µm, respectively). (c) Thin L-glutamic acid crystals (130 µm). (d) Taurine crystals (150 µm) viewed with cross polarizer films. (e) Strontium aluminate phosphorescent particles (80 µm). (f) Phosphorescent crystal of [Ru(bpy)3]Cl2 (440 µm). (a–d) were in white backlight in Fig. 1, middle, while (e–f) were taken in the dark using UV in Fig. 1, right, on a glass slide.
