Abstract
Systems and methods for identifying optical filters within a surgical imaging device are provided. A system comprises a set of one or more light sources and a set of one or more image sensors of the surgical imaging device. The set of one or more light sources emits a set of one or more emission light pulses. The set of one or more image sensors detects reflection light of the one or more light pulses. The system determines, based at least in part on the detected reflection light, an identity of an optical filter of the surgical imaging device, wherein the optical filter is disposed in an optical collection path of the surgical imaging device.
Claims25
A system for identifying optical filters within a surgical imaging device, comprising:
- a set of one or more light sources;
- a set of one or more image sensors of the surgical imaging device;
- one or more processors;
- and
- memory storing instructions configured to be executed by the one or more processors to cause the system to:
- emit, by the set of one or more light sources, a set of emission light pulses, wherein emitting the set of emission light pulses comprises emitting a predetermined time-series of the emission light pulses selected to differentiate between a predetermined set of optical filters, wherein one or more of the emission light pulses have different characteristic wavelengths from one another;
- detect, by the set of one or more image sensors, reflection light of the one or more light pulses;
- and
- determine, based at least in part on the detected reflection light, an identity of an optical filter of the surgical imaging device, wherein the optical filter is disposed in an optical collection path of the surgical imaging device.
A non-transitory computer-readable storage medium storing instructions for identifying optical filters within a surgical imaging device, the instructions configured to be executed by one or more processors of system comprising a set of one or more light sources and a set of one or more image sensors of the surgical imaging device, to cause the system to:
- emit, by the set of one or more light sources, a set of emission light pulses, wherein emitting the set of emission light pulses comprises emitting a predetermined time-series of the emission light pulses selected to differentiate between a predetermined set of optical filters, wherein one or more of the emission light pulses have different characteristic wavelengths from one another;
- detect, by the set of one or more image sensors, reflection light of the one or more light pulses;
- and
- determine, based at least in part on the detected reflection light, an identity of an optical filter of the surgical imaging device, wherein the optical filter is disposed in an optical collection path of the surgical imaging device.
A method for identifying optical filters within a surgical imaging device, the method performed by a system comprising a set of one or more light sources, a set of one or more image sensors of the surgical imaging device, and one or more processors, the method comprising:
- emitting, by the set of one or more light sources, a set of emission light pulses, wherein emitting the set of emission light pulses comprises emitting a predetermined time-series of the emission light pulses selected to differentiate between a predetermined set of optical filters, wherein one or more of the emission light pulses have different characteristic wavelengths from one another;
- detecting, by the set of one or more image sensors, reflection light of the one or more light pulses;
- and
- determining, based at least in part on the detected reflection light, an identity of an optical filter of the surgical imaging device, wherein the optical filter is disposed in an optical collection path of the surgical imaging device.
