I want to illuminate a scene (small space) using LED to capture photographs or videos of some tiny objects inside the space. But am not sure if I should use a Laser LED, or simple LED or power LED. The volume (space) that needs illumination is about 125 cm^3. The walls will be painted white in matt finish to maximise illumination under minimised shining effect. Instead of of using a camera I may want to detect an object as an obstacle in front of the beam of light emitted by the diode. Which diode shall suite the most ?
Dear @ NandKishor,
welcome!
Laser are concentrated light beams with high coherency. It is not used to illuminate areas. To illuminate areas and volumes you use power LEDS they are intended for such applications. For photography and video may be the best type of light sources for small volumes is to use white power LEDS.
Best wishes
in this case there is no point to go for laser diodes which are monochromatic..just take some commercially available LED based "headlights"or illumination lights..
Often, is similar cases, telecentric illumination instead of 'white matt' might be more efficient e.g. https://www.edmundoptics.eu/knowledge-center/application-notes/imaging/telecentric-illumination-why-you-need-it-in-machine-vision-applications/
