Hi uCrew,
I’m getting quotes to add lasers to various spinning disks or line-scan systems we are considering and I’m realizing I don’t really understand why we need lasers for a spinning disk set-up (or necessarily for a line-scanner). If we have powerful polychromatic LED light sources (e.g. 500 mW/‘color’) and we only need about 100 mW of laser power, why couldn’t we use the LED in these applications (assuming coupling to an optical fiber)? I’m realizing I don’t know as much as I thought I did about the importance of coherent light, focal spots, etc. for these types of imaging, and using LEDs would potentially save 10-20k.
Thanks!
