(a) A schematic of DIH imaging system with specific application to Drosophila. (b) DIH fly observatory setup with He-Ne laser, spatial filter, collimation lens, fly arena (marked by box) with environmental control chamber (with pipe connected to humidifier) and the CMOS camera. (c) Fly arena loaded with Drosophila and fly food in food trays on the right wall with 10 mm scale bar. Current system would allow simultaneous recording of control and experimental flies. (d) Camera view of the arena, an inset of a magnified holographic image of a fly marked on the front wall and a 2 mm scale bar.
