Standoff Ultra-Compact μ-Raman Sensor for Human Research

Objectives:
- Inspect and identify the normal and abnormal cells, tissues, and biofluids (e.g., urine, serum, etc.) using a 532 nm pulsed laser within target distances of several centimeters (6 to 20 cm) and a line shaped laser spot-size 10 µm width by 5 mm height that would be suitable for astronauts’ health monitoring in space.

Goals:
- The goals of this research study are:
- Solve some of the limitations of traditional micro-Raman systems (e.g., requires dark condition, sample collection, and slow)
- build an instrument with pulsed-time gated Raman technology, operates in daylight, doesn’t require sample collection, and faster detection
- Reduce the size and weight of the instrument
- eliminate a high power laser and a large collection optics/telescope with a short working distance of several centimeters.
