Abstract: Exemplary embodiments of a system for detecting biological objects are provided. In this regard, an exempliieary embodiment of such a system includes a light source, a sensor proximate to and disposed at an angle from the light source, a covering material disposed above the sensor, a photodetector proximate to the sensor and disposed at an angle relative to the light source, a non-light transmitting partition disposed between the light source and the photodetector, the partition configured to isolate the photodetector from the light source, and a non-light transmitting housing encasing the light source, sensor, and photodetector.

Abstract: Biological measurement and detection systems are disclosed, and methods for using the device. One exemplary system is configured to measure the intensity of light reflected from a sensor after a biological or non-living object is disposed in proximity to or remotely from the sensor. One exemplary method of using the biological detection system demonstrates the influence of living, biological objects (e.g., man's palm, laboratory animals, apple, etc.) on the system's indications of light intensity. The disclosed devices and methods can be used for a non-contact evaluation of a functional state of biological objects.
